Trinity Site - All You Need to Know BEFORE You Go (2024)

Trinity Site: What you need to know before you go

how to visit the trinity site

WHITE SANDS MISSILE RANGE — At precisely 5:29:45 a.m. on July 16, 1945, a tremendous explosion in the New Mexico desert signaled the beginning of the end of World War II.

The explosion was the world's first atomic bomb and as part of the Manhattan Project, it had been tested at the Trinity Site, now known as the north end of White Sands Missile Range.

Today Trinity Site is open to the public at 8 a.m. but closes promptly at 3:30 p.m.

According to White Sands Missile Range, the atomic bomb released 19 kilotons of power, instantly vaporizing the tower it was on and turning the surrounding asphalt and sand into green glass. The shock of the bomb broke windows 120 miles away and was felt by many as far away as 160 miles.

Success of the test meant an atomic bomb using plutonium could be used by the United States military in Japan during World War II.

Tour the Trinity Site

Touring the Trinity Site is free but it's only opened to the public twice a year, on the first Saturday in April and October. Thousands of visitors enter the site from either the Stallion Range Gate or the Tularosa Gate.

Entering the site from the Tularosa Gate entails joining your vehicle in a caravan at Tularosa High School football field parking lot, 1305 Eight St., in Tularosa. This caravan enters the site at 8 a.m. and is led by military police. From the Tularosa Gate, it's a 75-mile drive to the site and there are no gas stations on the route or at the site.

Everyone 18 and older must show a valid driver's license , pass port or DoD issued identification. All vehicles are subject to search and should be carrying proof of insurance and current registration papers. No weapons of any kind are allowed on the installation.

Entering the site from the Stallion Range Gate is a 17-mile trip and visitors are allowed to drive in and out of the site unescorted from 8 a.m. to 2 p.m. The Stallion Range Gate is located five miles south of U.S. Highway 380 and the turnoff is 12 miles east of San Antonio and 53 miles west of Carrizozo. 

Both roads are paved and marked. The site closes promptly at 3:30 p.m.

At the site, visitors can take a quarter-mile walk to ground zero where a small obelisk marks the exact spot where the bomb was exploded. Historical photos are mounted on the fence surrounding the area. Visitors also can ride a missile range shuttle bus two miles to the Schmidt/McDonald ranch house. The ranch house is where the scientists assembled the plutonium core of the bomb.

Tularosa Basin Downwinders

The Tularosa Basin Downwinders believe the Trinity test disturbed the genetics of residents in surrounding communities, leaving a cluster of cancer and illness in the those who witnessed the atomic bomb, and their descendants. For 13 years, the Downwinders have collected data, met with New Mexico's U.S. senators and continued fighting for inclusion in the Radiation Exposure Compensation Act (RECA).

Semiannually when the Trinity Site opens to the public, the Downwinders host peaceful demonstrations at the Stallion Range and Tularosa Gates, informing visitors about their cause.

The Downwinders have been invited twice to testify in front of Congress during hearings for RECA amendments but both times the hearings have been postponed. The Downwinders were recently given word that the hearings might be rescheduled for this summer and are preparing to travel to Washington, D.C. 

Last month, the Downwinders hosted a town hall in Carrizozo and listened to residents who were just 33 miles from the Trinity Site when the atomic bomb was tested.

Trinity Site Offers a Rare Chance to Visit Ground Zero of the World’s First Atomic Bomb Explosion

The detonation site is only open to civilians twice a year

Jennifer Nalewicki

Travel Correspondent

Detonation 1

July 16, 1945 was a day that changed the world forever. At 5:29 a.m. Mountain War Time, just minutes before sunrise, the night sky above central New Mexico was illuminated in a brilliant fireball of white light as the U.S. military tested the world’s first atomic bomb . Called Trinity Site and located on the grounds of the White Sands Missile Range about 70 miles west of Alamogordo, the site is typically off limits to civilians—but on October 7, visitors can experience it firsthand during its biannual open house.

Held on the first Saturday of every April and October, the open house is the only opportunity the public has to access the missile range, which normally serves as an active site for the U.S. Army to test out new weaponry. During the open house, visitors can see ground zero, where the plutonium-based A-bomb was detonated more than 70 years ago as part of the Manhattan Project . The open house also includes a visit to the McDonald Ranch House, a 1913 adobe home built by Frank Schmidt, a German immigrant, and where the device’s plutonium core was assembled.

Today, a monolith marks ground zero along with what’s left of the footing of a 100-foot tower that military personnel used during the detonation. Also on view: photos taken during the explosion, and the leftover bomb casing from “ Fat Man .”

how to visit the trinity site

“Most of the tower was vaporized during the explosion,” Drew Hamilton, a public information and community relations specialist for White Sands Missile Range, tells Smithsonian.com. “Since the explosion, much of the surrounding area has more or less returned to the way it would naturally be. There are no bushes growing around ground zero, but it’s because we regularly mow it. If we didn’t, it would look like the rest of the landscape.”

Visitors may also come across crumb-size pieces of Trinitite, a rock-like byproduct leftover from the explosion known for its glassy texture and deep green hue. (Since White Sands is a national monument, however, visitors are prohibited from removing anything from the site.)

how to visit the trinity site

And while Trinity Site has been cleaned up since the atom bomb detonation, its  radiation levels  remain above that of naturally occurring background levels. To put this into perspective, Hamilton gives the following example:

“Radiation is everywhere, it’s a naturally occurring phenomenon,” he says. “But it’s a little bit higher [at Trinity Site as compared to] the surrounding territory. During a one-hour visit, you’ll be exposed to approximately half a millirem of radiation. In comparison, during a flight aboard a commercial airliner from New York City to Los Angeles, you’ll be exposed to 2 millirems. You’ll get the same exposure from the Trinity Site as you would if you ate eight bananas, which, because of their potassium content, are naturally radioactive.”

This year’s Trinity Site open house will take place from 8 a.m. to 2 p.m. on October 7. Admission is free and reservations are not required. Pets are allowed and must be leashed. To reach Trinity Site, take exit 139 off Interstate 25 to State Highway 380 and drive east 12 miles to Stallion Gate. Make sure to bring a valid ID to show at security checkpoints. Drivers should be prepared to provide proof of insurance.

Trinity site.

US DEPARTMENT OF ENERGY

Trinity Site is located on White Sands Missile Range and is closed to the public. Twice a year, the US Army hosts a Trinity Site Open House when the public may visit Trinity Site. 

On July 16, 1945, the atomic age began. Manhattan Project scientists detonated the first atomic device, known as “the Gadget,” at 5:29 am Mountain War Time at the Trinity Site in the Jornada del Muerto desert of New Mexico.  

For the Project Trinity test, the bomb was placed atop a 100-foot (30.48 m) tall steel tower that was designated Zero. Ground Zero was at the foot of the tower. Equipment, instruments, and observation points were established at varying distances from Ground Zero. The wooden observation shelters were protected by concrete and earthen barricades, and the nearest observation point was 5.7 miles (9.17 km) from Ground Zero. 

An incredible flash of light illuminated the sky as air temperatures rose to over 9,000oF (4982oC). Within seconds, witnesses saw the first mushroom cloud ever created by atomic weaponry. To most observers—watching through dark glasses—the brilliance of the light from the explosion overshadowed the shock wave and sound that arrived some seconds later. A multi-colored cloud surged 38,000 feet (11.58 km) into the air within seven minutes. Where the tower once stood was a crater one-half mile (804 m) across and 8 feet (2.43 m) deep. Sand in the crater was fused by the intense heat into a glass-like solid, the color of green jade. This material was given the name trinitite. The explosion point was named Trinity Site. 

Although no information on the test was released until after the atomic bombings of Japan on August 6 and 9, 1945, the flash of light and shock wave made a vivid impression over an area with a radius of at least 160 miles (257.49 km). Kenneth Bainbridge, director of the Trinity Test, called it “a foul and awesome display.” Despite months of speculation and wondering over what would happen, “the atom bomb did not fit into any pre-conceptions possessed by anybody,” according to future Los Alamos National Lab director Norris Bradbury. After three years of directing the project’s scientists and much anxious chain smoking at the Trinity Site, Robert Oppenheimer simply said to his brother, “it worked.”    

After the explosion, Trinity Site was encircled with more than a mile (1.6 km) of chain-link fencing. Signs were posted to warn people of radioactivity. By 1953, much of the radioactivity had subsided, and the first Trinity Site open house was held in September of that year. 

In 1965, Army officials erected a monument on Ground Zero. In 1975, the National Park Service designated Trinity Site as a National Historic Landmark. The landmark includes base camp, where the scientists and support group lived; the McDonald ranch house, where the plutonium core was assembled; as well as Ground Zero.

Trinity Site Open House Guide (New Mexico)

Over the years of turning out content for this blog, I’ve visited a lot of historical sites but I’ve never visited a site quite like the Trinity Site in New Mexico.

It’s an ultra-remote site barely ever open to the public and it’s home to one of the most pivotal moments in mankind’s history.

If you have any type of interest in the atomic era, this is a bucket-list worthy destination for sure.

In this article, I’ll tell you everything you need to know about visiting the Trinity Site’s open house.

Table of Contents

What is the Trinity Site?

The Trinity Site is where the first nuclear bomb exploded on July 16, 1945 at 5:29 AM mountain war time. Two days out of the year there is an open house that allows the public to visit the site along with other related sites like the McDonald Ranch House.

How to visit the Trinity Site

It is free to visit the Trinity Site but you can only visit the site two days out of the yea r, which is usually the first Saturday of April and October. However, sometimes they do change the dates around a little bit.

There are three main ways that you can visit the Trinity Site.

Alamogordo Caravan

One way to experience the Trinity Site is to take part in the Alamogordo Caravan.

Line up for the caravan begins at 7:00am at the Tularosa High School Athletic Field parking lot and the tour will enter the missile range through the Tularosa Gate at 8:00am and arrive at Trinity Site around 10am.

It is only open to the first 125 vehicles that show up. 

The journey is 85 miles one-way to Trinity Site.

Stallion Gate

The other way to experience the Trinity Site (which is the way that we did it) is to simply arrive at the Stallion Gate. This gate is located on the north side of the missile range on U.S. highway 380, 12 miles east of San Antonio, NM.

The Stallion Gate Hours are from 8:00 a.m. to 2:00 p.m. and the Trinity Site closes promptly at 3:30 p.m

Once you show up at the military testing site, you’re not allowed to take any photos until you arrive inside the Trinity site so keep that in mind.

It’s about a 30 minute drive from the Stallion Gate to the parking lot for the Trinity Site.

At the Stallion Gate, you’ll go through a security checkpoint where every passenger 18 years and older will need to show an ID and declare that they are not bringing in weapons or any illegal items. (It only takes a few seconds to get through.)

Once you arrive at the parking area, military personnel will direct you to your specific parking spot.

Book a tour

You can also book a tour to get you there.

For example, the New Mexico Museum of Space History offers a package deal where you can get a bus ride to and from the site, some snacks, and access to the museum.

We checked out the museum and thought that it was a pretty well done space museum. They also have a small exhibit on Trinitite which was cool to see.

Where to stay

You might consider staying in Albuquerque, New Mexico, or in Alamogordo which is where we stayed because we decided to explore the New Mexico Museum of Space History and White Sands National Park the next day.

If you’re headed to Albuquerque, be sure to check out The National Museum of Nuclear Science & History and consider adding Los Alamos as an additional stop.

Los Alamos was the headquarters for the Manhattan Project and they still have a couple of museums you can check out like the  Los Alamos History Museum  and the Bradbury Science Museum .

Trinity Site history

To fully grasp and appreciate the history of the Trinity Site it helps to understand how it fits into the overall efforts of creating the atomic bomb.

The history of the atomic bomb begins in Berlin, Germany when in 1938, scientists discovered how to split the nucleus of the uranium atom (fission).

This discovery came close to the beginning of World War II when Adolf Hitler invaded Poland in September 1939.

The breakthrough in fission created serious worry that the Nazis would get their hands on a nuclear weapon which would obviously not be ideal to say the least.

Concerned Hungarian physicists helped write a letter to President Roosevelt (FDR), signed by none other than Albert Einstein, to warn the US about the prospect of an “extremely powerful” Nazi atomic bomb.

how to visit the trinity site

After that, it didn’t take long for FDR to authorize a top-secret project to begin researching the atomic bomb.

The initiative went through a few name changes but ended up as the: Office of Scientific Research and Development (OSRD).

Things took off after the bombing of Pearl Harbor on December 7, 1941 when the US found itself involved in World War II with a formal declaration of war on both Japan and Germany.

President Roosevelt authorized the Manhattan Project on December 28, 1942 and on the 18th floor of 270 Broadway in New York City, the Manhattan Project began.

General Leslie Groves was appointed to lead the Manhattan Project after just just finishing the completion of the Pentagon.

Groves went on to recruit Robert Oppenheimer, an instructor at the University of California at Berkeley and a bit of an odd selection given his lack of managerial experience and associations to communism via family members.

But he proved to be an ideal candidate and an excellent recruiter of scientific talent.

how to visit the trinity site

The Manhattan project sought to create atomic bombs from two substances: uranium and plutonium.

For uranium, they were focused on acquiring U-235 and they built a huge complex and town in Oak Ridge, Tennessee to accommodate 30,000 workers .

For Plutonium, the Hanford Engineer Works produced plutonium at a site along the Columbia River in Washington state.

They also needed a place to develop and test the bombs.

They wanted somewhere secret and remote but still appealing enough to attract renowned scientists all over the world so they went with Los Alamos, New Mexico.

On January 1, 1943, the Los Alamos Laboratory — known as Project Y — was formally established .

And a few months later , the University of California signed a contract with the United States Army Corps of Engineers to operate the secret laboratory.

They once again built an entire city just for the purpose of the Manhattan Project and hundreds of people would arrive to the city with no clear idea as to what they were actually building.

(Pretty much only scientific personnel had an idea of what they were doing.)

Questions were highly discouraged and on paper the city didn’t actually exist.

Many experiments were done as the teams collaborated to construct the bombs and waiting for the nuclear material to arrive. At some point, though, it became clear that the plutonium bomb was going to be an issue.

The issue was that creating an explosion with plutonium was a much more complicated process.

The scientist had to create an entirely different type of mechanism to initiate the chain reaction and that’s when they came up with implosion.

The implosion-type nuclear weapon , “held a core of subcritical plutonium which would reach criticality when high explosives surrounding the core detonated causing the core to compress instantly.”

The creation of this new type of work and was so challenging that it required bringing in a lot more scientists. Unfortunately, when bringing in more talent at least one Russian spy made his way into the team.

The team would ultimately make progress but unexpected challenges arose in April 1945 and the work was interrupted when FDR died in office.

Shockingly, the Vice President Harry Truman did not even know about the Manhattan Project when he took office!

A month later, on May 7, 1945, Germany would surrender but the war was still going strong in the Pacific Theater and an atomic weapon was being considered for use against the Empire of Japan.

The allies had battered the Empire of Japan’s military down to a shadow of what it had been before but casualties were still running very high.

But before any bombs would be dropped, some testing needed to be done.

Testing at the Trinity Site

Back in September 1944, around the time nuclear material was arriving, New Mexico’s Alamogordo Bombing and Gunnery Range (aka the Trinity Site) had been selected as the the test location .

It was located about 210 miles south of Los Alamos, and in November 1944 construction of the base camp began.

All of the components of the uranium atomic bomb had been tested giving scientists the mathematical certainty they needed to know that the bomb would work.

But because the plutonium bomb was more complex they needed a test run to ensure that it would work.

The plutonium bomb set to be tested at the Trinity Site was known as “Gadget.”

how to visit the trinity site

The core of the bomb consisted of a grapefruit-sized ball of plutonium and was delivered to the McDonald Ranch House on July 11, 1945 and the bomb was assembled on July 13, 1945.

The bomb, a large 6-foot sphere covered with wires and patched up with tape, was then hoisted up a 100-foot steel tower for the test.

how to visit the trinity site

At the time, none of the scientists truly knew what was going to happen. In fact, many thought the bomb would be a dud.

On the day of the test, the weather did not cooperate at first and the team postponed the test until the skies cleared up a little bit.

Then at 5:29:45 a.m. Mountain War Time on July 16, 1945, first atomic bomb was tested .

After the bomb exploded, clouds of bright reds and purples filled the sky up to 40,000 feet high. People said they felt the warmth of the sun.

Local newspapers were told that an ammunition depot had exploded which had resulted in the spectacular display but those at the site knew the truth: humankind had entered the atomic age.

how to visit the trinity site

The Trinity site

Ground zero.

Ground Zero is about a quarter mile away from the parking lot so you have to walk a little bit to get there.

trinity site

Once you arrive, you’ll see a monument towering in the middle.

Erected in 1965, The Trinity Monument is a lava-rock obelisk about 12 feet (3.7 m) high that marks the explosion’s hypocenter.

Crowds gather around the monument pretty quickly so you might need to exercise some patience to get a photo.

trinity site monument

Right next to the obelisk, you can find the remains of the 100 foot steel tower that hoisted Gadget.

trinity site steel tower remnants

Along the perimeter of Ground Zero, you’ll find photos hanging from the fence that will give you some insight into everything going on at the time of the test. It’s best to start from right to left when viewing these.

There’s a structure that covers some of the original soil from the test but sand and dust got in and covered up the original soil so the viewing window has been closed.

trinity site

There’s also a bomb casing that I believe was going to be used for future atomic bombs. It’s almost identical to the casing used for the fat man bomb which was dropped on Nagasaki.

trinity site monument fatman bomb casing

Trinitite is a radioactive green glass-like substance that covered the depressed area where the explosion took place after the test.

There’s different explanations as to how the trinitite was formed.

The simple and long-held explanation is that the heat simply heated the sand until it became glass.

One hypothesis is that the explosion brought pieces of sand and rock into the fireball and liquefied the pieces which eventually fell down like rain into the crater and hardened.

I’m not sure which explanation might be more accurate but I think it’s safe to say that it had a lot to do with the heat from the explosion.

trinity site trinitite

Most of the trinity it is light green but other pieces are slightly different colors. Some are black and others look slightly red and that’s because those contain elements that were vaporized during the test.

For example, the black pieces contain elements from the steel tower and the red pieces contain elements from the copper in the wires.

If you stroll around Ground Zero and look closely at the ground it won’t be very difficult to find pieces of trinitite.

They possess background levels of radiation and you are okay to touch them but probably not a good idea to do something stupid with them like swallow them. It’s also a federal crime to remove them from the property.

You’ll also want to stop by the trinitite fueling station. Here, you can get a close look at trinitite and also use a geiger counter to detect the radiation levels of the trinitite.

trinity site trinitite

McDonald Ranch House

The McDonald Ranch House is where they assembled the bomb on July 13, 1945. Built in 1913 by Franz Schmidt, a German immigrant and acquired by the McDonald family in the 1930s, the ranch was eventually taken over by the government in 1942.

In order to get there, you need to head to the bus stop which is located right by the parking lot. It’s only about a 5 to 10 minute bus ride to get to the ranch house. Keep in mind that dogs are not allowed on the bus unless they are service animals.

how to visit the trinity site

When you arrive, you can simply wander through the McDonald Ranch House at your own pace. There should be somebody inside that can help answer any questions you might have and who can show you around.

They also had a table with photographs set out in front so you can learn a little bit more about the structure.

McDonald Ranch House

The northeast room was designated the assembly room where they had work benches and tables.

McDonald Ranch House Assembly room

To keep all of the sand and dust from ruining the instruments, they covered the windows and walls with plastic. In fact, you can still see some of the nails that were used to seal up the windows.

McDonald Ranch House Assembly room door

As mentioned above, the plutonium core was delivered to the ranch house on July 11, 1945 and it was assembled on July 13, 1945.

The explosion occurred only 2 miles (3.2 km) away and it blew most of the home’s windows out but did not significantly damage the structure.

Instead, it was the years of rain water leaking through the roof that was responsible for the deterioration.

In 1984 it was restored by the National Park Service to appear as it did on July 12, 1945

Near the main parking lot you’ll see Jumbo which is a large structure which was once the heaviest object to ever be transported by rail.

The 25-foot jumbo container was initially going to be used to contain the plutonium with its 14 inch thick walls in the event of a botched explosion.

However, after they realized that they would have plenty of plutonium for additional bombs they didn’t need to use jumbo for the explosion.

So they hoisted it from a tower about 800 yards away from ground zero and while that tower would be vaporized during the explosion, jumbo would remain intact.

While they did not use it for this explosion, it was used on April 16, 1946, when an Army ordnance team detonated eight 500 lb bombs in the bottom of the steel container.

trinity site jumbo

Food and souvenirs

You’ll also be able to find food and souvenirs at the Trinity site.

Souvenirs range from about $3 to $20 and they have a lot of the typical stuff like magnets, stickers, patches, and T-shirts.

how to visit the trinity site

As for food, they’ll have breakfast burritos, hamburgers, hotdogs, and some other snacks. I believe the registers should take credit cards but I would bring cash just in case.

how to visit the trinity site

Also, they do have bathrooms which are a little bit of a walk from the parking lot.

Visiting the Trinity Site is not very easy because it is only open two days out of the year and it’s basically in the middle of nowhere.

But it is still absolutely worth planning out a visit because it’s hard to find a location that compares to the Trinity Site in terms of its importance to the history of mankind.

The Trinity Test Site Is Open One More Time This Year. You Might Not Get In.

Plaque on the obelisk that marks ground zero at the Trinity Site

The Army said the only day for tourists to visit the Trinity nuclear test site in New Mexico this year could be packed amid the massive popularity of the blockbuster movie "Oppenheimer."

White Sands Missile Range, where the U.S. detonated the world's first nuclear weapon known as "the Gadget" on July 16, 1945, as part of the Manhattan Project, is open to the public only twice a year. The development effort, led by theoretical physicist Robert Oppenheimer, was spurred to outpace Nazi Germany's pursuit of its own weapons of mass destruction.

The next date for tourists to visit the site is Oct. 21, and then again on April 6, 2024. For the rest of the year, the site is used for non-nuclear Department of Defense weapon and radar tests. Usually on each of the two days the site is open to the public every year, the Army sees some 3,000 visitors but expects 5,000 in October. Visitation is first come, first served.

"Due to the release of the movie 'Oppenheimer' in July, we are expecting a larger than normal crowd," a message from the Army said. "You may experience wait times of up to two hours getting onto the site. If you are not one of the first 5,000 visitors, you might not get through the gate prior to its closure at 2 p.m."

Army officials consider the site safe for visitation . Radiation levels are above normal levels in the surrounding area but far below the exposure in an X-ray or CT scan. One hour at ground zero is roughly equivalent to a long commercial flight across the U.S.

The tour is free, though a service spokesperson told Military.com that the missile range cannot accommodate anyone who cannot walk a half mile round-trip on a dirt trail.

The Trinity site is in a desolate location in the middle of the desert 130 miles south of Albuquerque, New Mexico. The main attraction is a roughly 12-foot-tall obelisk commemorating the detonation in what was a monumental scientific achievement. The development of much more powerful atomic weapons also marked a dark turn for modern warfare by introducing the potential to create instant destruction on a scale that had been unimaginable before.

The test blast was witnessed from as far as 200 miles away and broke windows as far as 160 miles away as the mushroom cloud reached more than 50,000 feet into the atmosphere . Because the bomb was detonated on top of a tall tower, the crater was only about four feet deep and 240 feet in diameter. The heat from the blast was 14,000 degrees Fahrenheit. It melted the desert sand, turning it into a glass-like substance.

The Trinity bomb was completed after the German surrender. But the U.S. was still planning a massive invasion of mainland Japan, in which fatalities were expected to dwarf the rest of the war, including the invasion of Nazi-occupied France.

As many as 400,000 to 800,000 American troops were expected to be killed in the invasion, more than the entire war up to that point. Some five to 10 million Japanese were expected to die as the Imperial government was imploring its citizens to fight to the end, including the use of suicide bombings.

President Harry Truman authorized the only use of nuclear weapons in combat in August 1945 after Japan declined to surrender.

A U.S. B-29 Superfortress bomber dropped the atomic bomb nicknamed "Little Boy" on the city of Hiroshima on Aug. 6, 1945. As Imperial Japan clung to its war effort and again did not surrender, Truman used another bomb -- named "Fat Man" -- three days later on Nagasaki.

Together, the bombs killed between 129,000 and 226,000 people.

The last time the U.S. tested a nuclear weapon was in 1992.

Trinity Site plaque

To reach the spot where the nuclear age was born and human history swung, turn off of Route 380 at Stallion Gate on the northern edge of the US Army’s White Sands Missile Range, not far from the tiny desert town of Socorro, New Mexico. Drive through the flat, dry, empty scrub the Spanish called Jornada del Muerto, or the Journey of Death, ringed at the horizon by the Sierra Oscura, the Dark Mountains.

After 17 miles or so you’ll reach a vast parking lot that stands largely empty much of the year. Walk past a mangled 200-ton steel tube called Jumbo, and stand before a stone obelisk mined from nearby volcanic rock. The words on the plaque will tell you where you are: Trinity Site — where the world’s first nuclear device was exploded on July 16, 1945 .

Trinity has largely faded from the public consciousness, overshadowed first by the horror of the atomic bombings of Hiroshima and Nagasaki, and later altogether as the fear of the bomb itself began to recede in the post-Cold War era. After World War II, the Interior Department tried to create a national monument at Trinity Site, but its efforts were continually frustrated by the military, which wanted to retain White Sands to test its growing inventory of missiles away from the public.

In truth, Americans have never known what to think about Trinity, simultaneously the greatest of technical and scientific achievements, the culmination of the Manhattan Project, and the birthplace of the first weapon of mass destruction, where the means to kill millions was tried and tested. It wasn’t until 1975 that Trinity Site was finally declared a National Historic Landmark — a few ranks down from a National Historical Park — and even now it remains largely closed to visitors, save for two Saturdays a year in April and October.

You can expect crowds to grow this fall, because the Trinity test is the hinge of Christopher Nolan’s hit biopic Oppenheimer , on the man behind the Manhattan Project. But what does it feel like to stand at the spot of Ground Zero, the site where, as Matt Damon’s General Leslie Groves says in the film: “the most important fucking thing to ever happen in the history of the world” actually happened?

The day the sun rose twice

I had a chance to visit Trinity Site myself in the spring of 2018, when I was researching my book End Times: A Brief Guide to the End of the World . I’m not sure what I expected as I broiled under the New Mexico sun. A moment of existential clarity? Some monument that represents the enormity of what happened here, the moment and the place where human beings demonstrated that they would now have the power to destroy themselves?

But save for a two-inch chunk of concrete left from the original tower, and the bits of glassy green called trinitite that were liquified in the blast before falling to the earth as hardened shards, there’s little indication at Trinity Site today of what occurred more than 70 years ago. And even the more immediate aftermath left some of the witnesses underwhelmed. A few weeks after the test, Gen. Groves, the director of the Manhattan Project and Oppenheimer’s boss, was driven out to the site on an observation trip. A Manhattan Project physicist remembered Groves looking at the crater left by the first atomic bomb and remarking : “Is that all?”

But no one who witnessed the day the sun rose twice ever forgot the experience, a fact ably captured in Nolan’s magisterial recreation of the event. The day of my visit to Trinity, frame-by-frame photos of the moments after the bomb’s detonation were arranged against the fence. Here’s how I described it in my book:

At 0.006 seconds there is a bubble of perfect light, as if the dawn itself had blossomed suddenly out of the desert ground. The heat of the blast is thousands of times hotter than the surface of the sun, and the light in that single moment was a dozen times brighter. At 0.025 seconds, the bubble head keeps rising, while a fringe of fire spreads across the ground… At 0.053 seconds, that perfect bubble begins to lose its clarity, becoming diffused and unfocused, as if overwhelmed by its own energy, while the inferno at the surface expands, gouging out the earth below. At this point every living thing within a radius of a mile is dead, or will be soon. At 0.10 seconds, the blast looks like nothing less than a halo on the head of some Renaissance painting of Christ, as the exposure itself begins to degrade. The atomic heat has made the air grow luminous, as the force of the shock wave expands outward, shredding the matter in its path. Everything is ravaged, everything is burned. And at 15 seconds after detonation comes the familiar image of the mushroom cloud, what the art historian John O’Brian called “the logo of logos of the 20th century” ... That mushroom cloud — like nothing seen on Earth before — is the result of intense heat at the heart of the blast, causing the air to rise in a column, before it spreads out in a mushroom’s cap.

In their definitive biography American Prometheus , the source material for Nolan’s film, Kai Bird and Martin J. Sherwin wrote that no one can know what flashed through the physicist’s mind as he beheld the thing that he, more than any other person, had willed into being. Oppenheimer’s brother Frank remembered that, “I think we just said, ‘It worked.’”

More than his words, it was Oppenheimer’s countenance in the aftermath that was telling, another moment Nolan captures perfectly. The Manhattan Project physicist Isidor Isaac Rabi recalled it this way: “I’ll never forget his walk. I’ll never forget the way he stepped out of the car…his walk was like High Noon …this kind of strut. He had done it.”

Yet the site of Trinity itself today contains nothing of this triumphalism, just as it has nothing to say about the tens of thousands of people who would be killed in a few short weeks by the descendants of that original bomb.

Was it a scientific victory? An unmitigated horror? All a visitor to Trinity has is their thoughts, a bare plaque, and the silent, endless desert that surrounds them.

Where the ending began

How should we remember Oppenheimer and Trinity? Far better than we do now. Despite Bird and Sherwin’s biography, which won the Pulitzer Prize in 2006, and Richard Rhodes’s equally great 1986 book The Making of the Atomic Bomb , which features Oppenheimer as a central character, both he and the test itself have received far less than their due. Oppenheimer wasn’t a president or a general, and while an excellent theoretical physicist, he was not among the 20-some scientists connected to the Manhattan Project who had already won or would go on to win a Nobel Prize.

And yet without Oppenheimer’s ability to motivate and corral fractious scientific egos, and the sheer drive that was a product of what Groves called his “overweening ambition,” the Manhattan Project would likely never have succeeded. And Trinity was the proof of that success. Nolan’s film goes a long way toward correcting that score.

But Oppenheimer’s success contained within it the seeds of its own destruction — something Oppenheimer himself, a lifelong student of Hindu thought, might have appreciated. At the end of the film, Oppenheimer is seen visiting Albert Einstein on the peaceful, leafy campus of the Institute for Advanced Study at Princeton, far removed from Trinity’s bare desert. Oppenheimer reminds the older scientist of an earlier conversation, when Manhattan Project physicists worried that a nuclear bomb might inadvertently ignite the atmosphere .

“When I came to you with those calculations, we thought we might start a chain reaction that might destroy the entire world,” Oppenheimer says.

“What of it?” Einstein replies.

“I believe we did,” Oppenheimer says.

What is Trinity Site? It is the place where those calculations were proven in nuclear fire, the Ground Zero where one possible end for us all began.

How to Visit Trinity Site: A Journey Through History

This site may contain affiliate links. We may receive a commission for purchases made through these links.

The Trinity Site is the location where, on July 16, 1945, the first nuclear bomb in history was detonated. Thanks to Christopher Nolan’s film, “ Oppenheimer ,” the site has gained renewed and significant attention in public opinion worldwide.

If you’re wondering whether it’s possible to visit, the answer is yes, but several aspects must be considered. Let’s then explore everything there is to know about the Trinity Site.

Why to visit Trinity Site

Trinity site: a monument within the largest military installation in the united states, pricing and operational hours: details about admission fees, operating hours, and more, what you must know: understand the nuances of visiting trinity site, is trinity site still radioactive, where to stay in the area, about trinity site.

trinity site new mexico

The Trinity Site is located within the military boundaries of the White Sands Missile Range . It derives its name from the test that led to the explosion of the first atomic bomb, which also resulted in the creation of trinitite , a glassy material that formed in the crater created by the atomic explosion due to the heat emitted. These fragments still have low levels of radioactivity and can be handled for a limited time without causing harm to one’s health.

In 2018, almost all of the remaining debris at the site was collected and buried, and now it is strictly prohibited by law to collect them. During your visit to the site, you will notice many signs reminding visitors of this prohibition.

However, during public openings of the Trinity Site, pieces of trinitite that were recovered in previous years by collectors and enthusiasts may be on display.

Exploring the Trinity Site offers a unique and profound opportunity to step back in history . Visiting the site is not just about witnessing the location of a significant scientific achievement; it’s about understanding the impact this event had on the world, marking the end of World War II and starting in the atomic age.

It’s a journey that offers insight into the complexities of human ingenuity and its consequences, making it a must-visit for those interested in history, science, and the broader implications of human actions.

Very likely, before entering the military base, you may encounter a group of people with protest signs . These are the so-called Downwinders who lived in New Mexico. Unlike those residing in other states, they were not evacuated before the explosion and were excluded from federal compensations provided to those who experienced health issues due to exposure to nuclear radiation after various tests.

Let’s then explore what there is to see at the Trinity Site.

Ground Zero

trinity site cosa vedere

This is the location where Gadget, the first nuclear bomb, was detonated . You will have to walk for just under 1600 feet along a road bordered on both sides by a metal fence to reach this spot from the parking area where you leave your car.

Upon reaching Ground Zero, don’t expect to enter a crater. Instead, you will find a stretch of arid land with a central obelisk made of volcanic rock bearing a commemorative plaque. Along the fence, you’ll also see a series of historical photos.

You can also observe the casing of the Fat-Man bomb that was dropped on Nagasaki.

McDonald Ranch House

McDonald Ranch House

If you prefer, a shuttle service is available that will take you to the McDonald Ranch House, which is the location where the plutonium core of the Gadget bomb, later detonated at the Trinity Site, was assembled.

The house was originally constructed in adobe in 1913 by Franz Schmidt, a German immigrant who settled in this area of New Mexico. It was later purchased in the 1930s by the McDonald family. However, in 1942, when the U.S. Army took possession of the land for aerial bombing testing, the McDonald family was forced to abandon their home, receiving a compensation of $60,000.

The atomic bomb explosion, which occurred just over 1.8 miles away, did not damage the structure but only shattered the windows. Nonetheless, in 1984, a decision was made to restore the house to address damages caused by weathering and abandonment, aiming to closely resemble its original appearance in 1945.

Near the house, you can see the remains of water tanks that were used as a pool during a hot summer in 1945, as depicted in a historical photo on display.

Located within the expansive White Sands Missile Range , the largest military installation in the United States, the Trinity Site holds a unique position in both history and geography.

This significant location is set against the backdrop of a vast testing ground for missile technology , encompassing a diverse landscape that has played a crucial role in defense and research developments since 1945. The range itself, stretching across the deserts of New Mexico, offers a glimpse into the nation’s military prowess and technological advancements.

To gain a deeper understanding of the history of this area, I invite you to read our in-depth feature on the White Sands Missile Range Museum .

Visiting Trinity Site

Unfortunately, visiting this area in person is quite complicated as it can only be done twice a year .

Yes, you understood correctly. You can participate in a tour of the Trinity Site only on the first Saturday of April and the fourth Saturday of October . The dates are not fixed and can change from year to year. For example, the upcoming tour is scheduled for April 6, 2024. For this reason, I recommend checking the official U.S. Army page for the most accurate information.

There are two access options to the area: one through Stallion Gate , located along Highway 380, and the other using the Alamogordo Caravan organized by the Alamogordo Chamber of Commerce.

  • Alamogordo Caravan : This is a caravan of vehicles (limited to a maximum of 125) led by military police, departing at 10:00 AM from the Tularosa High School Athletic Field parking lot. You can start lining up from 8:00 AM. To participate, you need to have a photo ID such as a passport, show your rental agreement, ensure your vehicle has a full tank of gas, and have a spare tire. Once the caravan starts, it will enter the military base through the Tularosa Gate , and no stops will be allowed along the route.
  • Alternatively, you can access through Stallion Gate from 8:00 AM to 2:00 PM by presenting a photo ID like a passport. There is no reservation system, so your chance to visit the Trinity Site depends on your arrival time and the number of people present. Be prepared to wait for a few hours before entry due to both the significant influx of people and the necessary checks at the entrance (keep in mind that you are entering the boundaries of an active military base).

It is not allowed to take photos or videos along the route inside the military base, but you can take photos and videos only once you arrive at the Trinity Site.

Given the unique nature of the site we are visiting, it’s possible that over time, the hours and access procedures may change. For this reason, I always recommend checking the official website for the latest information.

In addition to personal visits, there are other ways to tour the Trinity Site, namely through private tours that require booking and have associated costs. Here are the main options:

  • The City of Socorro Transportation Department offers a shuttle service departing from the Socorro Transportation Office at 201 Church Street at 8:00 AM, with a return at 12:00 PM, at a cost of $2 per person. More information is available on the official website .
  • The New Mexico Museum of Space History organizes a guided tour to the Trinity Site at a cost of $125 per person, which includes breakfast, lunch, and a museum visit upon return. More information is available on the official website .

Despite the historical radiation release, today’s visitors can be reassured by the fact that radiation levels at the site have diminished to the point where they’re considered safe for brief visits. The comparison of radiation exposure from spending an hour at the site to everyday activities— like taking a cross-country flight —puts into perspective the minimal risk involved.

Visitors are reminded not to collect Trinitite , the glassy substance created by the bomb’s detonation, as it remains radioactive. Furthermore, as mentioned earlier, it is strictly prohibited to do so.

Certainly, staying within the White Sands Missile Range is not an option, but if you wish to remain in the vicinity, I recommend looking for accommodation in the major towns surrounding the military area. Among the most notable are:

  • Alamogordo : You can find all available hotels at this link .
  • Las Cruces : Explore all available hotels at this link .
  • Truth or Consequences : Discover all available hotels at this link .

NBA star Dennis Rodman has an Olympian as a daughter

Dennis Rodman /  Trinity Rodman

NBA legend Dennis Rodman isn't the only athlete in his family.

His soccer-playing daughter, Trinity Rodman , will be kicking it in Paris, France, this summer with the U.S. women's national team .

Trinity is a forward, which is a star-making spot on the USWNT. The position has made Megan Rapinoe  and  Alex Morgan global stars. She was only 18 when she was the No. 2 overall pick in the draft, which at the time was the record for the youngest NWSL player ever drafted.

After joining the Washington Spirit soccer team in 2021, Trinity was named the NWSL Rookie of the Year. In 2022, she was nominated for the Ballon d’Or Féminin in 2022, recognizing the best players in women’s soccer around the world. In 2023, she became the youngest player in NWSL history to record 10 assists and 10 goals in a regular season career and the youngest player in Spirit history to make 50 appearances with the team.

“She’s an all-out competitor,” former Spirit head coach Kris Ward told  ESPN . “Her ability to withstand pressure and close contact with the opponent and her desire to help her team succeed — she’s a change-the-game player. There hasn’t been anyone like her before.”Though Trinity appears to be a bit more subdued than her flamboyant father, she still has that distinctive Rodman flair.

Rodman, who was estranged for years from his own father, has spoken about wanting to be a better dad to his three children.

“The only major, major demon I have right now is trying to convince myself that I am a good dad,” he  told ESPN  in 2019. “It’s very hard for me to try to break out of that cycle.”

Keep reading to learn more about Dennis Rodman’s three children.

Alexis Rodman

Dennis Rodman and his first wife, Annie Bakes, were only married for 82 days, but the pair welcomed daughter Alexis Rodman into the world on September 28, 1988.

Alexis married Robert Bunfill in 2014 and gave birth to a son named Vincent, making Dennis a grandfather.

He expressed his joy on a post on X in 2017, writing, "Wow, congrats to my daughter Alexis and her husband for the birth of their 1st baby: Vincent! I can’t believe I’m a Grandfather!"

Dennis “D.J.” Rodman Jr.

Dennis was married briefly to second wife, model Carmen Electra, before having a son and a daughter with his third wife, Michelle Moyer.

Dennis "D.J." Rodman Jr. was born on April 25, 2001, and he has been following his dad to the basketball court.

DJ Rodman #10 of the USC Trojans

D.J. has been playing college basketball, first at Washington State University and then at the University of Southern California.

According to his team website , D.J., a graduate student, is a 6-foot 6-inch, 225 pound forward "who is a tough defender and top-notch three-point shooter."  

Like his famous father, D.J. has been repping some popular brands .

Trinity Rodman

Born on May 20, 2002, Trinity is close in age to D.J., and their bond seems to be a strong one.

In this Instagram video, Trinity said, "One of my favorite things to do is watch my brother compete. Seeing him on the court is the best thing ever."

She went on to say about watching her brother play, "It's an emotional roller coaster for me, but I think I'm definitely his biggest hype woman. I'm cheering. I'll yell at the refs, even."

Her bond with her father doesn't seem to be as close.

When Dennis surprised his daughter by attending one of her games with the Washington Spirit, she wrote in an Instagram post , "My dad doesn’t play a big role in my life at all and most people don’t know that, we don’t see eye to eye on many things. I go months if not years without his presence or communication. Being in spotlights has been hard for us, him and me. We don’t have the best relationship, but at the end of the day he’s human I’m human… he’s my dad, and I’m his little girl and that will never change."
