Mulu Caves: Everything You Need To Know [2024]

Located inside the Gunung Mulu World Heritage Area, the Mulu Caves boast an extensive network of caves renowned for their size, complexity and geological formations such as stalactites, stalagmites, and limestone pinnacles. These formations have been sculpted over millions of years and are a sight to behold.

They are unique and fairly straightforward to visit tucked away on the island of Borneo in the state of Sarawak.

There is a whole range of Mulu Caves from Show Caves (caves that can be visited easily without special training or equipment) to Adventure Caves (which are more adventurous to visit). There’s the Deer Cave which has the longest cave passage open to the public or the Sarawak Chamber which is the largest cave chamber in the world.

All up, it’s an amazing place to visit.

In this guide, I share a full Mulu Caves review based on my experiences visiting the Mulu Cave Sarawak Malaysia. It has everything you need to know about visiting these caves including Mulu Caves facts, Mulu Caves tour package options, ticket prices and how to get to Mulu Caves Sarawak. I also share detailed information about the main caves.

You can also read my full guide to visiting Gunung Mulu National Park here . This gives you everything you need to know about this area in addition to the Mulu Caves in Sarawak. There are other things to do in this area too and it has your accommodation options and more.

Mulu Caves 2024

The history of the Sarawak Mulu Caves starts about 5 million years ago when the first caves started to form here. Sideways movements of the Earth lead to the formation of side-by-side limestone and sandstone mountains.

Add in millions of years of heavy rain and this flowing water cut out the huge cave complex that you can visit at Sarawak Caves Mulu. In fact, this is still continuing today with caves shaping and shifting as time goes by.

The exploration and scientific research of the Mulu Caves began in the 19th century. In 1858, the British adventurer Spenser St. John explored some caves in the area, but it was not until the mid-20th century that more systematic expeditions were conducted.

Expeditions in the 1920s, 1930s and 1960s lead to more caves being discovered as well as documentation of the unique flora and fauna inhabiting the area.

In 1974, the Gunung Mulu National Park (also called Mulu Caves National Park Sarawak) was established, encompassing the Mulu Caves and the surrounding rainforest. The park was designated a UNESCO World Heritage Site in 2000, recognising its outstanding universal value and ecological importance.

Over the years, numerous scientific expeditions and studies have been conducted within the Mulu Caves. These investigations have contributed to our understanding of cave geology, speleology (the study of caves) and the ecology of the rainforest ecosystem.

The Gunung Mulu Caves have also attracted attention from adventure seekers and cave enthusiasts. The challenging terrain and the allure of exploring vast cave systems have drawn explorers and cavers from around the world. Adventurous expeditions have pushed the boundaries of cave exploration, mapping new passages and documenting their geological formations.

Although you don’t have to be adventurous to come here to enjoy and learn about the caves. Today, it’s never been easier to visit with a range of Show Caves and tours to make it extra easy and interesting. The tours to visit are also very reasonably priced.

The Malaysia Mulu Caves also continue to be a hub for scientific research and conservation efforts. The park authorities work closely with local communities to preserve the cultural and natural heritage of the area while allowing visitors to experience the unique wonders of the caves and the surrounding rainforest.

The Caves are deep in the rainforest, and it does take some trekking, boating and effort to get to them. However, things are made as straightforward as possible so you can visit the Show Caves which are the caves that don’t take any special training or equipment to visit.

Directly below, I share more information about the individual caves including how to get to them from inside the Mulu Caves National Park Malaysia. Below this is more information about the location of the national park, Mulu Cave tour package information and other practical information you’ll need for your trip.

The first four caves described are the most popular (and for good reason). I highly recommend you book tours for these. Note that all caves can only be visited with a guide.

Make sure you wear great shoes as paths can be slippery. Also take a raincoat, water, torch and a snack for longer tours.

Mulu Deer Cave

Deer Cave is the biggest show cave at Mulu Caves in Malaysia and also has the largest cave passage in the world. It’s over two kilometres long and 174 metres high. It was formed by a fast flowing river that used to come through here.

Deer Cave is located in the Southern Hills area of the park and is a 3.8 kilometre walk from park headquarters on wooden planks which were in great condition when I visited with most looking like they were recently replaced. The walk itself is easy and relatively flat. There are some inclines and declines – but nothing that noticeable.

With your guide, you are able to walk about 800 metres inside the cave and get to see many sights including Adam and Eve shower heads which are ceiling spouts that water flows through. However, the part that is really amazing and enjoyable about walking through this cave is how big it is. It’s huge!

On the tour, you follow a path through to the passage to the Garden of Eden at the end. There are plenty of viewpoints where you get great views of the cave.

The path is boardwalk, metal paths and stairs. It is slippery at time, although nothing too terrible and there is plenty of guano around (bat poo). It smells disgusting and you’ll get some great views of the guano as well!

This is because the cave is also home to 2.5-3.5 million bats that cling to the roof.

You are able to walk until the Garden of Eden which is a point where the ceiling collapsed, and you can see out into the rainforest. It’s very pretty. You can also here running water here.

Tours then turn around and head back out. The way our guide did this is that he went last and we could take our time walking out. This was great as I felt like I had the cave to myself at times – amazing! Especially since it was a busy day when I was here.

Tours to Deer Cave include Lang Cave as well which is where you’ll walk to next. It’s right next door. Some tours also do the caves in reverse order.

After you visit the two caves, the tour ends and you can watch the bat exodus on the way back to headquarters. This is the name given to when the bats that live in Deer Cave exit the cave in twirling clouds of bats. There is a special Mulu Caves bats observatory to watch this from.

This observatory is a short walk from the cave. There are toilets here as well as a small stall selling drinks and snacks.

The bats can exodus anytime from 4pm with about 5:30pm being common. It’s an amazing sight! Unfortunately, there is no guarantee that they will come out. It’s especially unlikely in heavy rain but it was clear and beautiful weather when I was here, and they did not come out either.

This is about 3 kilometres from headquarters so you’ll most probably walk back in the dark. Make sure you have a torch.

Tours depart around 2pm to visit this cave and they take about 3 hours plus time taken to watch the bat exodus and get back to headquarters. The walk to the caves is about an hour with the guide pointing out flora and fauna along the way. I found I only took about 30 minutes to walk back.

Lang Cave Mulu

Lang Cave is smaller than Deer Cave with cool stalagmites, stalactites, rimstone pools and limestone shawls.

This cave was formed by standing water eroding the limestone rather than a river and it’s interesting seeing the differences.

Where Deer Cave was BIG, Lang Cave is intricate with lots of details to check out and enjoy.

This is a path through the cave which does a loop at one point and there are some stairs. It’s an easy walk though, and I did not find it slippery. Our guide pointed out various features as we went through.

Again, we were able to walk out at our own pace and really take it in.

This cave is visited as part of the Deer Cave tour described above.

Wind Cave is named after the cool winds that blow through here. You’ll feel it when you hit the narrow part of the walk. There are some impressive chambers here such as the King’s Chamber which is filled with stalagmites and columns. There are lots of intricate details and formations to check out. It’s quite amazing actually and perhaps my favourite cave.

It reminded me of Lang Cave (which I had seen the day before), but on a much bigger scale. Lang was maybe slightly prettier though and I felt like I was closer to the formations in that smaller cave.

There is also Sky Garden which is where a sinkhole in the roof of the cave allows light in. This light has allowed plants to grow on the walls of the cave, It’s very pretty.

This cave was also formed by a river running through it and our guide pointed out how you could tell and also described the differences in how caves are formed if it’s a slow flowing river versus a fast one.

Wind Cave and Clearwater Cave (coming up next) are visited together as part of a tour leaving around 9am and taking up to four hours. These caves are located in the Gunung Api section of the park.

To get to them requires a scenic longboat ride up the Melinau river. It’s also possible to hike 4 kilometres instead, but the boat ride is very enjoyable. The scenery is amazing and it’s nice and cool. I loved it.

On the way, you get to stop at a Penan longhouse and market at Batu Bungan. At the (tiny) market, you can buy Penan (the local indigenous tribe) handicrafts (woven baskets and mats and jewellery). I read beforehand that this wasn’t open on Sundays, but I went on a Sunday and it was open.

However, I saw no sign of a longhouse to visit or any blow dart demonstrations which I had also read about here. My guess is that this may not have come back since the pandemic.

After the market, we hopped back in the boat and then headed to Wind Cave.

It’s an uphill walk on a wooden pathway to Wind Cave. It’s not steps, but an inclined path with wooden panels on top of the path to stop it being slippery. It’s fairly short and not that hard.

Inside the cave is wooden boardwalk as well as a concrete path and steps. One part if quite narrow, but the good part is that there is some cool air in here.

After we explored this cave, we were back on the boat and heading to Clearwater Cave.

Mulu Clearwater Cave

Clearwater Cave is named after the crystal clear river that runs over 200 kilometres through this cave system. It’s one of the biggest cave systems in the world at 220 kilometres.

You only get to see a small part on this tour (although it is possible to see more for experienced cavers). The cavern you get to walk through is HUGE! And the roar of the river is clearly heard as it rushes through making this cave even bigger.

That’s part of what makes this cave interesting – that you can see how the river is shaping it.

It also has many unique rock formations, stalagmites and more. I was glad I went here last as it was a good combination of features I had seen in the previous caves. It was BIG (but didn’t feel as big as the huge passage in Deer Cave) and had interesting formations as well.

It was a great Show Cave to finish with.

Clearwater Cave is visited on the same tour as Wind Cave as described above.

After you arrive by boat at this cave, there is a rest area. Our tour stopped here for about 20 minutes before continuing. I booked this tour through the National Park Headquarters, but there were many tours here from private operators that had meals set up at this rest area. It would be a fabulous place for lunch and I was a little jealous.

Next to this rest area is a swimming area in a natural lagoon with water from the cave. You can swim after the cave visit. There are also toilets here.

To get to the cave takes 200+ steps. It is quite a sweaty climb, but it’s worth it. I found it was over quicker than I thought it would be.

The walk through the cave is the trickiest one, but it’s not really that tricky. There’s boardwalk, steps with a rope to help pull yourself up and a bridge over the rushing river below. It’s an interesting cave with plenty to see.

After the 200+ steps back down to the rest area, it’s time for an amazing swim. The water is cold, but after a minute, I loved it. It felt great on my (incredibly hot and sweaty) body. I am not really a sweaty person but it was humid on these cave visits and the water was the perfect way to cool down.

It’s surrounded by the rainforest as well and the whole area is stunning. I can’t recommend a swim here enough. I wish I had time to come back and have another swim!

Then it’s a boat ride back to Park Headquarters.

Lagang Cave Mulu/Fastlane

The final Show Cave you can visit is Lagang on the Fastlane tour. This visit is more intimate than the others with groups of six only allowed in at a time. This keeps things darker and makes for a more interesting experience.

Lagang Cave is famous for its stalactites, stalagmites and intricate formations. It also has large passages and walkways that take you from the bottom to the top of the cave.

Most of the tour is by torchlight and you can see the unique fauna and flora that call this cave home including blue racer snakes, swiflets, bats and large cave insects.

The Fastlane tour departs around 2pm and lasts for two and a half hours. To get here involves a short boat ride and a 15-20 minute walk through the rainforest and up steps to the entrance. There’s then a 1.5 kilometre walk through the cave.

If you are an experienced caver, there are also more adventurous tours of this cave.

Adventure Caves

Experienced cavers will find plenty to do at Mulu Caves Malaysia. There are beginner, intermediate and advanced experiences, and they can all book out so book in advance. Most are full day trips but some are half day or overnight.

There are options in the Clearwater Cave and Lagang Cave described above or you can explore Racer Cave or Sarawak Chamber which is an overnight adventure.

You can find more details on adventure Mulu Caves Sarawak tours here .

Where Is Mulu Caves Sarawak Malaysia?

Address: Gunung Mulu National Park, Miri, Sarawak

Mulu Caves are in the Gunung Mulu World Heritage Area close to the Mulu Airport.

Flying is the most realistic way of getting here with daily flights from Kuching, Kota Kinabalu and Miri to Mulu Caves on MASwings, a regional operator for Malaysia Airlines. I flew from Kuching to Mulu and then on to Miri afterwards and it was very straightforward.

From the Airport, it’s a quick transfer or 15-20 minute walk to Park Headquarters where all tours to the Mulu Cave Malaysia start.

You can find more details on how to get to Mulu in my full guide here.

Mulu Caves Ticket Prices

You don’t pay for the caves individually and instead pay for tours which include visiting the caves. Prices are correct at time of publishing.

The tour to Deer and Lang Caves costs RM35.

The tour to Wind and Clearwater Caves costs RM67.

The Fastlane tour to Lagang Cave costs RM65.

You also need to pay for the Mulu World Heritage 5 day pass. If you stay in the World Heritage Area for more than five calendar days, you’ll need a second pass.

Currently, this costs RM30 for foreign adults and RM10 for kids 6 – 18 years old. Malaysians pay half the price.

Mulu Caves Package

Mulu Caves is not somewhere you visit on a day trip. You need to stay at least overnight or, ideally, at least a couple of nights. There is plenty to see and do around the Mulu Cave National Park in addition to the caves.

While you could just show up and try to organise everything, this is a tiny place. There are only so many beds you can stay in and tours you can do and there are more seats on flights coming into Mulu than there are tours and beds. Especially during peak times from June to September and in Malaysian school holidays, you should book everything in advance.

Thankfully, it is not hard to book Mulu Caves packages. You can google a local travel agent in Malaysia who can book it all for you or you can book direct with the Mulu Caves tour operator here .

I booked direct online before I went and it was all very smooth.

You can also read our guide to Mulu accommodation here.

Best Time To Visit Mulu Caves In Sarawak

The Mulu Caves best time to go is in the dry season from June to September. However, this coincides with the peak season so that can also make it trickier to visit then. This time period as well as Malaysian school holidays are peak times to visit so book a minimum three months in advance then.

Book all your cave tours as well because they can sell out and there is no way to go inside the Mulu Caves in Borneo without one of these tours.

This is a rainforest though, and it can rain at any time. Afternoons are particularly likely to be wet at any time of year, so it’s not a big deal to visit at other times.

Final Words

The Gunung Mulu National Park Caves are amazing and I highly recommend you visit them and at least try to get to the four main show caves.

They are each unique and beautiful in their own way and the setting in the ancient rainforest helps take the whole experience to another level.

I also recommend visiting Deer and Lang Caves on the first day and Clearwater and Wind Caves second. The latter are the better ones, in my opinion, and it’s nice to keep seeing better and better ones.

I absolutely loved spending a few days here exploring nature and the Mulu Caves Borneo.

Overview of Location

Sarawak, the largest state in Malaysia, is located on the island of Borneo, and it is there that Mulu National Park resides. Because of its extraordinary biological value, Mulu has been designated as a UNESCO World Heritage Site. 

Mulu National Park has an impressive 52,000 hectares of unspoiled tropical rainforest, home to a wide variety of flora and wildlife. At 2,376 metres tall, Gunung Mulu towers over the surrounding landscape, which features deeply carved canyons, wild long winding rivers, limestone pinnacles jutting into the sky, and towering vegetation that sweeps down onto a remarkable concentration of caves, revealing a geological history spanning over 1.5 million years. You may find fascinating information everywhere. 

Geomorphic and structural features provide scientists, naturalists, and tourists with stunning landscapes, breathtaking beauty, and a deeper knowledge of Earth's past. There are over 17 vegetation zones displaying around 3,500 species of vascular plants. 

More about Camp 5 and the Mulu Pinnacles

From the thicket of plants that surround them, a succession of 45-meter-tall, razor-sharp limestone spikes emerge. It's like a postcard from the past brought into the present day, with the rocks eroded into sharp spears by water over millennia and poking up through the canopy of the nearby jungle like arrows.  Seeing the Pinnacles is worth the effort, although it is one of the most difficult hikes in the park. You may reach the Mulu Pinnacles by taking a longboat journey down the Melinau River, then hiking for 9 kilometres to Camp 5, and continuing on the steep ascent of 2.4 kilometres up the Pinnacle Summit Trek.   Due to safety reasons, the National Park has set a total of 4 checkpoints to the Pinnacle Viewpoint Summit. At each checkpoint, there is a cut-off time. At any of the checkpoints, if you miss the cut-off time, you will not be able to continue your climb. 

The Cut-Off Times for Each Checkpoint for The Mulu Pinnacles Hike are as below: 

During the first 400m climb to the summit, make sure that you get to the first checkpoint within 60 minutes, then reach the next 1.2km within 30 minutes, 60 minutes to reach the next 2km and 45 minutes to the Pinnacles viewpoint. If you are unable to reach the checkpoint within any of the cut-off times, you will not be permitted to continue your climb due to safety reasons. 

Camp 5 may be found in the vicinity of the Melinau Gorge, which divides Gunung Benarat and Gunung Api. The camp offers dorm-style sleeping quarters with shared kitchen and bathroom amenities. After making the journey from Long Berar, cool up with a dip in the crystal-clear Melinau River in front of Camp 5. 

More About the Mulu Show Caves

The sheer beauty and originality of the four exhibition caves in Mulu are representative of everything that makes Mulu National Park a fascinating and valuable World Heritage Site. It is possible for tourists visiting Mulu to explore the cave system without prior caving or spelunking expertise. Deer Cave and Lang's Cave can be reached via a boardwalk through the forest, while Clearwater Cave and Wind Cave can be reached via a longboat ride up the Melinau River or a 4-km nature route. 

All of the exhibition caves are easily accessible through elevated boardwalks and well-lit walkways, and may be explored in a day excursion from the park headquarters. Stalactite and stalagmite formations at Lang's Cave, for example, are illuminated by carefully placed lights in the display caverns. 

Sample Itinerary

Arrival / deer & lang's caves / bat exodus.

Guests arriving at Mulu Airport will be transferred to either Mulu Marriott Resort & Spa or Mulu National Park for check-in. In the late afternoon, meet your local guide and travel together to explore Deer Cave and Lang's Cave before enjoying a break on the bat exodus platform and watching the bats emerge from the cave entrance. Then, return to your stay and enjoy free time at your own leisure. You may wish to explore the park's several unguided trails!

Lunch / Dinner Mulu Park HQ Longhouse / Mulu Marriott

Check Out / Batu Bungan / Wind & Clearwater Caves / Kuala Litut / Camp 5

After breakfast, check out and start your journey by longboat to Batu Bungan – Penan Settlement, then to Clearwater Cave and Wind Cave. 

First, marvel at the stunning cave formations while feeling the cool air blow through the cave at Cave of the Winds. 

Next up, Clearwater Cave has a massive entrance, so be prepared to climb some very high stairs to reach it. The local tour guide will go over the cave procedure before you enter the cave. Take a refreshing dip in the cave’s cool stream and soak in the glow of the stalactites and stalagmites that line the cave’s interior.

For lunch, the group will have a nice picnic in the clearing near the entrance to Clearwater Cave. 

Finally, go back on the motorised longboat that will transport you up the Melinau River to Kuala Litut. The boat will need to be pushed over the rocks if the water level is too low for it to float. The 9-kilometre trek from Kuala Litut to Base Camp 5 takes around two to three hours and covers reasonably level forest terrain. After a restful night at Base Camp 5, enjoy a hearty meal prepared by your local guide. 

Breakfast / Lunch / Dinner Base Camp 5

Camp 5 / Gunung Api / Pinnacles / Camp 5

Have a hearty breakfast before you start your hike to the Pinnacle Summit at approximately six in the morning. From Camp 5 to the Pinnacles lookout, you'll gain around 1,200 metres in elevation while only travelling 2.4 kilometres. The path ascends precipitously into a moss forest after descending through a lowland dipterocarp forest. Little trees remain, and moss grows on almost everything else. The trail is littered with sharp pieces of limestone, so hikers should make sure to always be cautious. 

Due to the difficulty of the trail's final stretch, 15 aluminum ladders and a rope portion have been strategically placed along the path. The ascent is likely to take you four or five hours. 

Check out / Kuala Litut / Mulu National Park / Mulu Airport

Prepare to depart Base Camp 5 after breakfast. To get back to where you started, you'll hike nine kilometres to Kuala Litut and then take a longboat ride down the Melinau River and back to the National Park. 

Transfer to Mulu Airport and prepare for your departure.

3D2N Mulu Caves - A Unesco World Heritage

Tour program.

DAY 1 Arrival at Mulu airport and transfer to Mulu Marriott Resort & Spa or Mulu National Park. Proceed to the National Park Headquarters for registration and lunch at the Park's canteen.

After lunch, you will take an approximately 45 minutes' walk along a wooden plank path through riverine and lowland limestone forest leading to Lang's Cave. Explore this beautiful cave with its stunning stalagmites and stalactites, followed by the Deer Cave with the largest cave passage in the world. This cave also houses an estimated 2 million bats, so be prepared for the stinging smell of guano.

After the exploration of these two amazing caves, you will proceed to the bat observatory platform. If weather permits you will witness the bats emerging from the cave in spiraling black streams.

Walk back to the Park's Headquarters the same way and return to your accommodation.

Overnight at Mulu Marriott Resort & Spa, Deluxe Room or Mulu National Park, ROH. (L)

DAY 2 After breakfast, you will embark on a 30-40 minutes boat ride (depending on water level). During a short stop at a Penan settlement, you can learn about their formerly nomadic lifestyle and visit a small handicraft market.

Then proceed by boat to Wind Cave. Climb up a few stairs to the cave entrance. Inside the cave you will sometimes feel a slight breeze, which gave this cave its name. You will also find the beautiful King's chamber with its astonishing rock calcite formations. After exploration of this cave, take a 10 minutes' walk to the Clearwater Spring, where you will take a short break.

In order to reach the entrance of Clearwater Cave, you need to climb 200 steps. Inside the cave many more steps await you. But it is worth it, as this cave is probably the most impressive amongst all, with a system of cave passages of more than 100 km length.

A simple picnic lunch will be served at the Clearwater Spring, after which you may enjoy a swim in the cool clear water of the Clearwater Spring.

Return to your accommodation. The afternoon is free at your own leisure to enjoy the beautiful natural environment or to sign up for one of the many other activities (not included in the package) offered by the National Park, such as a canopy walk, a trek to a waterfall or a night walk. There is also a short and easy botanical loop trail for you to venture on, with interesting information boards about the amazing flora of Mulu National Park. If you were not lucky to see the bats the evening before or simply want to witness the natural spectacle one more time, you may also walk on your own to the bat observatory to try your luck again.

Overnight at Mulu Marriott Resort & Spa, Deluxe Room or Mulu National Park, ROH. (B/L)

While some are inaccessible to tourists, many of the world’s most famous caves contain distinct rock formations, underground bodies of water, and other fascinating highlights, making them major attractions for locals and visitors alike. It’s humbling to think that there are some caves large enough to house New York City's epic skyscrapers and entire city blocks within them. Here are the largest caves in the world and where tourists can find them.

Kazumura Cave, Hawaii

• This is the longest and deepest lava tube in the world.

For anyone in Hawaii, the Kazumura Cave is one not to miss. Here lies the lava tube, which has been surveyed at 40.7 miles long and 3,614 feet deep, making it the longest and deepest lava tube in the world. The Kazumura Cave in Hawaii is located on the island of Hawaiʻi on the eastern slope of Kīlauea and is one of the more recently active in the area. Tourists are unable to go inside the cave as it is an active volcanic site, but there are tours in the surrounding area. After all, Hawaii is filled with stunning scenery (volcanoes and beyond), so this is a hidden gem.

Fingal's Cave, Scotland

• This cave is known for its impressive acoustics.

Another massive cave worth exploring is Fingal's Cave in Scotland. This cave is not only on the uninhabited island of Staffa, in the Inner Hebrides of Scotland, but is also known for its natural acoustics. Many tourists will venture to the cave to scream, sing, and hear the vast echoes of afar. Fingal's Cave is accessible by boat, making it a nice sight for those willing to get on the water. Moreover, this cave's length varies between 227 feet (69 meters) and 270 feet (82 meters), and its arched roof is said to reach between 66 feet (20 meters) and 72 feet (22 meters) above the sea.

During low tide, guests have the best access to Fingal's Cave.

Clearwater Cave System, Malaysia

• This cave system runs 30+ miles and exists in a UNESCO World Heritage Site.

Situated in Miri, Sarawak, Malaysia, the limestone Clearwater Cave System consists of a series of interconnected caves rather than just a single one. Clearwater - on its own - has been mapped to just above 30 miles; however, Clearwater Cave System is more than just its longest member. Discovered in the late 1970s, the cave system exists within Gunung Mulu National Park, which is a UNESCO World Heritage Site .

In the Clearwater Cave System, people will find an underground river, as well as a plethora of unique rock formations. Containing an exceptionally large passage, the Clearwater Cave System is one of the longest of its kind in Southeast Asia and serves as a major tourist attraction. The amazing thing about caves is that nobody knows their true size. Clearwater is still being explored to this very day.

Hölloch Cave, Switzerland

• This is one of the biggest caves in the world that tourists can enter.

Tourists can enter the Hölloch, one of the biggest caves in the world. This enormous underground marvel is 124.5 miles long and impressively deep at 3079.3 feet. The Hölloch is a natural wonder not to be missed, with its striking limestone structures and subterranean waterways.

Lechuguilla Cave, New Mexico

• Located within the Carlsbad Caverns National Park.

Lechuguilla Cave is located within Carlsbad Caverns National Park in New Mexico . A limestone and gypsum cave spanning more than 138 miles , Lechguilla is full of interesting mineral formations that have attracted the interest of geologists around the world. While discovered in the 1950s, approximately three decades would pass before Colorado would permit the cave to be explored further. Since the decade of hair metal, explorers have investigated Lechuguilla Cave while marveling at its beauty.

Wind Cave, South Dakota

• This is one of the oldest National Park cave attractions in the United States.

Wind Cave National Park is one of the oldest of its kind in the United States. Another cave that’s classified as a “maze cave” due to its convoluted structure and many underground passages, Wind Cave's density is staggering, even compared to other caves on this list. Those visiting the cave should also take some time to explore the national park in which it resides.

Wind Cave National Park is brimming with picturesque views and serves as a protective habitat for the local wildlife.

Shuanghedong Cave Network, China

• This is the longest cave network in China and the continent of Asia.

The Shuanghedong Cave Network is the longest cave in China and Asia , situated in Guizhou. Running for more than 150 miles, the network was discovered in 1987 and is a fine example of underground ecosystems. There are at least three rivers in the lower levels of the cave, as well as a number of waterfalls.

Within these bodies of water live creatures such as fish and salamanders. Since its discovery in the late 1980s, various expeditions have been carried out in an attempt to map the passages and discover the cave's secrets.

Optymistychna Cave, Ukraine

• Ukraine boasts the longest gypsum cave in the world.

Earning the crown for the longest gypsum cave, Optymistychna Cave in Ukraine extends for over 161 miles and is divided into 10 different areas. These are based on the various passage structures and gypsum varieties found within. Optymistychna Cave, located in Korolivka, Ukraine, is widely known as a maze cave due to the fact that it is extremely elaborate and a little complicated to navigate.

Visitors should be prepared for a lot of mud, especially in the depths of the cave.

Sistema Ox Bel Ha, Mexico

• This cave runs within a 30-mile radius of Mexico's other largest cave system.

Mexico’s Sistema Ox Bel Ha is located within a 30-mile radius of the country’s other largest cave system, Sistema Dos Ojos. Discovered in 1996 and spanning over 160 miles , Ox Bel Ha is thought to have begun forming approximately 18,000 years ago. The name Ox Bel Ha comes from the Yucatec Maya language and translates to “Three Paths of Water” in English.

Since its formation, Ox Bel Ha has become flooded due to the effects of global warming. Today, the system is valued as one of the prominent sources of freshwater in the region.

Mulu Caves, Borneo

• These caves are home to the Sarawak and Deer Chambers and hundreds of bats.

Home to the Sarawak and Deer Chambers, Mulu Caves houses hundreds of bats and one of the world's most impressive and largest cave formations. Some of the most stunning cave formations may be seen at the Mulu Caves, situated in the Gunung Mulu National Park on the island of Borneo (home to some of the biggest cave systems in the world) .

The Deer Chamber is one of the biggest underground tunnels on Earth, while the Sarawak Chamber, with a surface size of 1.66 million square feet, is the largest cave overall. Tourists may take guided excursions to explore their maze-like pathways.

Sistema Dos Ojos, Mexico

• This cave network runs for over 200 miles and is connected to other underwater caves.

Located in Tulum, Quintana Roo, Mexico, Sistema Dos Ojos was discovered in 1987 and has hooked the interest of explorers ever since. Running for over 200 miles , this limestone cave is connected to the underwater cave of Sistema Sac Atun.

According to Largest.org , Sistema Dos Ojos is considered a prime archeological site. Archaeologists have discovered information within this cave system that has led to many discoveries about a number of cultures. After the channel connecting Sistema Dos Ojos with Sistema Sac Atun was discovered, this cave system became known as the largest underwater cave in existence.

Sac Actun, Mexico

• This is the largest cave system in Mexico.

The greatest cave system in Mexico is an underwater one, and new parts of it are constantly being found and investigated. Sac Actun is one of the world's largest underwater cave systems; it presently extends over 228 miles as new caverns are found.

Mammoth Cave, Kentucky

• Mammoth Cave is not fully understood or mapped yet.

It’s unknown how far Mammoth Cave actually extends, but to date, it has been recorded that the underground system stretched at least 365 miles . New caves in the network are constantly being discovered, so there’s no telling just how expansive the system really is - some believe it could be the biggest cave in the world, given that nobody knows its true size yet.

Humans have been exploring Mammoth Cave for over 4,000 years, and today, it’s still a major tourist attraction in Kentucky. A particularly stunning cave, it hosts a variety of stalactite formations. These were created through water that leaked through the limestone ceiling of the cave over the millennia.

People can visit Mammoth Cave National Park and see the cave for real .

Miao Room Cave, China

• This cave is only reachable via its underground stream.

The Miao Room is undoubtedly one of the largest caverns in the world. This chamber, 380,700,000 cu ft in volume , is only reachable via its underground stream. These measurements were discovered during a laser-mapping trip that was supported by the National Geographic Society, and they were then presented at the national caving conference in the UK.

Son Doong Cave, Vietnam

• The Son Doong Cave is one of the largest in the world, forcing guests to drop 260 feet to enter.

With caverns large enough to house a 40-story skyscraper, the recently discovered Son Doong Cave in Vietnam is the largest cave in the world and forces visitors to descend 260 feet just to enter its perimeters. Son Doong was discovered in 1991 by a man named Ho Khanh, who was living in the nearby jungle.

The first expedition to the cave was led by the British Cave Research Association in 2009. They found that Son Doong is more than 400 million years old . For those wanting to visit, Oxalis Adventures is the only company to run tours into the Son Doong Caves . Overall, this beast dwarfs many of the other largest caverns in the world, so it's a must-see for any cave enthusiast looking for their next adventure.

The entrance of the cave is 150 m wide and 120 m high. Nowhere in this massive cave is the roof less than 90 m high.

The stalactites and stalagmites inside this cave are representative of the very best limestone formations in the park. After viewing the two caves, proceed to the Bat Observatory outside Deer Cave. Most evenings at sundown, a spectacular exodus of about 2 million of bats can be observed as they leave the cave in search of food.

Moscow Metro

The Moscow Metro Tour is included in most guided tours’ itineraries. Opened in 1935, under Stalin’s regime, the metro was not only meant to solve transport problems, but also was hailed as “a people’s palace”. Every station you will see during your Moscow metro tour looks like a palace room. There are bright paintings, mosaics, stained glass, bronze statues… Our Moscow metro tour includes the most impressive stations best architects and designers worked at - Ploshchad Revolutsii, Mayakovskaya, Komsomolskaya, Kievskaya, Novoslobodskaya and some others.

What is the kremlin in russia?

The guide will not only help you navigate the metro, but will also provide you with fascinating background tales for the images you see and a history of each station.

And there some stories to be told during the Moscow metro tour! The deepest station - Park Pobedy - is 84 metres under the ground with the world longest escalator of 140 meters. Parts of the so-called Metro-2, a secret strategic system of underground tunnels, was used for its construction.

During the Second World War the metro itself became a strategic asset: it was turned into the city's biggest bomb-shelter and one of the stations even became a library. 217 children were born here in 1941-1942! The metro is the most effective means of transport in the capital.

There are almost 200 stations 196 at the moment and trains run every 90 seconds! The guide of your Moscow metro tour can explain to you how to buy tickets and find your way if you plan to get around by yourself.
