Mulu National Park is an UNESCO World Heritage Site listed in year 2000. Mulu’s limestone karst and isolated mountain peaks are home to numerous rare and endemic plants and animals. Whether you are looking for a tranquil escape in the rainforest of Borneo, the physical challenge of trekking summits and climbing through expansive cave systems or perhaps somewhere in between, Mulu will tantalize your senses and leave you wanting to discover more.
Deer & Lang Caves
- A 3km almost flat walk on raised plank walks takes you to the Bat observatory (45 minutes to 1 hour).
- Walk another 500m to reach one of the world’s largest cave passages, home to more than 3 million Wrinkle Lipped bats. A large number of swiftlets also roost in Deer Cave where the high cave ceilings (more than 100m in some places) provide a safe haven against predators.
- Enjoy the sheer size of this limestone passage, an ancient riverbed, and see the force of water carving the scalloped walls.
- Once you reach the green oasis of Garden of Eden you have walked 800m inside Deer Cave. Enjoy the unique shower head formations of Adam and Eve’s showers spouting columns of water 30m to the riverbed below.
- Returning almost the same way, but with views from different angles, you will visit Lang Cave with wonderful limestone shawls, stalagmites and stalactites. Bats are easier to see in this smaller cave and you will be very close to the shimmering webs of thread worm larvae, another miniscule wonder of Mulu caves.
- The tour is timed to coincide with the bat exodus which could start any time from after 17:00.
- To walk to Deer cave to witness the Bat exodus is a FREE excursion, BUT you cannot enter Deer or Lang cave without payment beforehand and a guide (as is the normal procedure). Expect to be back at HQ by 18:30 to 19:00, should the bats fly.
- A small kiosk at the Bat Observatory sells drinks and snacks until 17:30. PLEASE BRING YOUR EMPTY TINS/PACKAGING BACK WITH YOU TO HQ as per World Heritage prescription.
- Toilets and designated smoking area available.
Clearwater & Wind Caves
- Cruise up the Melinau river in a longboat and visit a Penan longhouse & market at Batu Bungan (market not open on Sundays).
- 2nd stop at Cave of the Winds where you have to negotiate a long ramp and a few stairs.
- 3rd stop Clearwater where the subterranean river emerges from the cliff face. Take 200 stairs to enter the cave to marvel at the Monophilia Pendula endemic to Mulu. Clearwater is one of the biggest cave systems in the world, measuring over 220km in length.
- Swimming inside the cave is not permitted, however a cool down in the natural crystal-clear waters at the picnic deck is a must. Float with the fish and enjoy the rainforest around you.
- The Park tour does NOT include any food & beverage, feel free to bring your own.
- PLEASE BRING YOUR EMPTY TINS/PACKAGING BACK WITH YOU TO HQ as per World Heritage prescription.
