It takes a lot of geological ducks to line up neatly in a row and stay there for a few million years to create a cave. All over Sarawak, home to one of the oldest rainforests in the world, those ducks have lined up numerous times as many of the most spectacular caves in the world were discovered and continue to be discovered right here.
Many of those already discovered are now ready for you to explore. But a word of warning, not all of these breathtaking, stunning subterranean caverns are easily accessible, but that just makes the most beautiful caves in the world all the more alluring.

Sarawak is a big state and the tropical weather can make travel to certain parts of the state challenging and exciting. And with so many outstanding caves, it can be difficult to decide which ones to visit first and in which order.
So, while each cave has its own unique beauty and each is incomparable to another, this post will help you appreciate the beauty of Mother Nature’s masterpieces in Sarawak while visiting at least some of them while you are in Kuching or Miri.
1. Sireh Cave, Serian
Located about 70km South of Kuching, Sireh Cave or Gua Sireh is a true hidden gem with its stunning rock paintings believed to be about 20,000 years old, large chambers and caved parts with clean underground water.

A trip to Gua Sireh can be made within a day. However, it isn’t an easy hike as there are some wooden steps and narrow passageways that one needs to get through. It is recommended to take a tour from Kuching where you can arrange to be picked up at your hotel. You can book tours to Gua Sireh here.
Upon arriving at Bantang Village, your journey continues on foot up a flight of wooden stairs that lead you up to the cave entrance. This is where you will be greeted with cave paintings estimated to be 20 millennia old and peculiar cave residents such as Cave Racer Snake, bats, insects and catfish.

The interior of the cave has some unique yet stunning shapes that are warm-toned swirls and curves decorated for effect. Believed to be one of the earliest human settlements, archaeological materials such as pottery shreds, animal bones and food debris from the Stone Age, New Stone Age, and the Iron Age, have also been recovered inside Gua Sireh.

It takes approximately 4 hours to tour the cave and remember to bring a change of gear when visiting Gua Sireh as the tour takes you through to the neighbouring Broken Jar Cave that requires you to walk through a pool of water.
2. Deer Cave, Gunung Mulu National Park

This UNESCO World Heritage site is home to millions of bats. It is said that between 2 to 3 million of them reside in here! The Deer Cave, which is probably Sarawak’s most famous cave, is located at Gunung Mulu National Park, about 90 minutes flying time from Kuching, or a 30-minute flight from Miri.
Deer Cave was only discovered in 1979 by British caver Andy Eavis whilst helping Malaysia better understand and appreciate the potential of the newly established Gunung Mulu National Park.
Deer Cave is the largest cave passage in the world. The entrance is so enormous-nearly 500 feet high- that the sun reaches deep inside and fresh air flows through the caves, allowing a peculiar, awe-inspiring habitat to exist.
As you walk through the cave, you’ll see millions of dark patches on the walls. Those are bats resting so try not to disturb them!

As the day ends and after you’ve explored Deer Cave, stick around for one of the most spectacular phenomena you’ll ever see.
The Deer Cave bat exodus happens every day at dusk. Millions of bats leave the cave to search for food. It’s an awe-inspiring event.
Nestled in the lush wilderness of Borneo, Gunung Mulu National Park is accessible by river and road but we recommend light plane. MasWings, a subsidiary of Malaysia Airlines, provides direct flights to Gunung Mulu National Park from Miri, Kuching, and Kota Kinabalu.
Upon arrival at Mulu Airport, book guided tours here or here. Most of the tours are all-inclusive and provide airport transfers. Accommodation is varied so do your research!
One other point, local communities who have lived off the land for thousands of years and respect and appreciate what it has provided them, have been trained as tour guides and will escort you throughout your visit to the caves. Make sure you pick their brains about the caves and ask about their beliefs!

3. Clearwater Cave, Gunung Mulu National Park
When you visit Gunung Mulu National Park, you will find a unique environment that stimulates all the senses. One of the many gems of this Park is the Clearwater Cave that is the 8th longest cave in the world at 227 km and the largest interconnected cave system in the world. No wonder it is a UNESCO World Heritage site!

The Clearwater Cave system contains an underground river and a plethora of unique rock formations. The amazing thing about these caves is that their true size is still unknown and even now, is still being explored.

Visiting Clearwater Cave in Sarawak is a real adventure that begins with the journey. There are two ways of getting to Clearwater cave.
From the park HQ, you can either trek the gentle 4km nature trail that takes approximately one and a half hours, or you can experience a long boat along the Melinau River with a stop at Wind Cave.

The Wind Cave features ancient, undisturbed stalactites and stalagmites that have, over hundreds of thousands of years, reached each other to create long structures known as pillars or columns. Once you’ve explored the Wind Cave, you can walk to Clearwater Cave in about 5 minutes.
When booking your tour for Gunung Mulu National Park, a visit to the Clearwater Cave and Wind Cave should be included as it is one of the must-visit sites at the park. If it isn’t, ask your agent to include it.
4. Sarawak Chamber, Gunung Mulu National Park
If you are into adventure caving, you must check out the Sarawak Chamber, one of the planet’s largest enclosed areas, natural or manmade. It is so huge, that it has enough space to house 8 jumbo jets in a row!

Getting to the Sarawak Chamber from the park HQ requires a full day of challenging adventure caving but some say that it is truly a once in a lifetime experience. The whole circuit takes about 10-15 hours which entails a 3-hour hike to Good Luck cave and then an 800m hike through a river channel to the Sarawak Chamber.

There are guided tours available to this magnificent chamber and you can find more information on the tours both here and here.
Before we move on from the Mulu Caves complex, if you seek even more adventure, you can attempt to hike the pinnacles of Mount Mulu. The hike is reportedly the most challenging hike in Malaysia (yes, even tougher than Mt. Kinabalu!) and requires a high level of fitness so make sure you train before you get here!
5. Niah Caves, Niah National Park
Located a mere 90kms south of Miri, the Niah caves are home to 65,000-year-old artefacts and cave paintings. It’s no wonder they are on track to be the next UNESCO World Heritage site. If that happens as expected, there will be a massive increase in visitors so you might want to get there soon, before the crowds!

The site is also home to the oldest human remains found in Southeast Asia which indicate the caves were inhabited at least 65 millennia ago. You can check out fascinating artefacts including prehistoric utensils and turtle shells that will be on display at the Niah Archaeological Museum from January 2020.
Most importantly, the park is a major source of income to the local tribes people who also earn a living collecting edible birds nests built by Swiftlets high in the cave walls. The sustainably collected birds’ nests are prized by Chinese gourmets around the world and are exported under a supervised environment.

Getting to Niah Caves is easier than Mulu National Park as it is accessible by road. The journey by bus from either Miri or Bintulu takes approximately 2 hours so you can easily make a day trip out of it.
If you’d rather join a tour, there are guided tours from both Miri and Bintulu and you can get more information on these tours from here and here.

No visit to Sarawak is complete without visiting her outstanding natural caverns. Whether you are a hardcore spelunker, an open-minded adventurer or an inquisitive visitor, Sarawak’s caves will provide memories and stories forever.
