Mulu National Park – Caves & Pinnacles

Day 1:   (-/-/-)
Upon arrival at Mulu airport, you will be transferred to your accommodation.
In the early afternoon, venture on a guided tour of the impressive Deer Cave and the Lang’s Cave. A wooden plank-walk leads from the National Park headquarters to the cave entrance (approximately 1 hour walk).
The Lang’s Cave is the smallest of the 4 show caves of Mulu, but boasts some of the most beautiful stalactites and stalagmites. Just a few hundred metres away you will find the entrance to the Deer Cave, the longest cave passage in the world. The main chamber is 174 meters wide and 122 meters high. Follow a winding path deeper into the dark cave passage (don’t forget your torch light!) to reach the “Garden of Eden”, where a hole on the cave ceiling let’s in sunlight and a jungle grew inside the cave. It truly deserves its name! It is also in Deer Cave that you will see the famous rock formation resembling the profile of Abraham Lincoln.
After the cave exploration, you will wait for the impressive exodus of bats. Weather-permitting, you may witness millions of bats leaving the cave just before sun sets in order to hunt for food.
Walk back to the headquarters, accompanied by the calls of hundreds of creatures that spring to life as night falls.
Choice of accommodation: National Park Chalet or Mulu Marriott Resort & Spa

Day 2:   (B/L/D)
After breakfast, embark on a boat ride up the Melinau river to the Wind Cave and Clearwater Cave. Along the way you will stop at a Penan village. Formerly nomadic people, some Penans have settled here, looking for a less strenuous way of living and trying to adapt to the changing world of modern days. Visit the handicraft market, to see the products of the skilled craftsmanship of the Penan.
Further upriver you will reach the Wind Cave. Explore the beautiful cave chambers with its spectacular rock formations and try to find out how this cave got its name.
A 10 minutes’ walk along a wooden walkway will lead you to a nice natural pool. From here you need to climb 200 steps to reach the entrance of the Clearwater Cave, which is Asia’s longest cave with a subterranean river system. And as the name suggests, the water is crystal-clear. A wooden walkway leads you deeper inside the cave. The size of this cave will make you feel like a dwarf, although you actually just get to see a tiny part of the real dimension of this breathtaking cave system.
Back at the natural pool outside the cave you will have a simple picnic lunch. If you wish you may take a cooling dip in the fresh water before you continue the boat ride to Long Litut (1-2 hours > depending on water level). Here is the starting point of the 8 km trek through the rain forest to Camp 5.
After a simple dinner, retire for the night in the dormitory-like accommodation of the camp.

Day 3:   (B/L/D)
After an early breakfast, get into your trekking footgear with proper grip and start your climb of Mount Api. Although the length of the trail is only 2.4 km, you will cover 1,200 metres of altitude! Therefore a good physical condition and high level of stamina is required! The last part of the trail is almost vertical, with ropes and aluminium ladders strategically positioned to help with the climb. After this tough challenge you will be rewarded with stunning views of the Pinnacles, a series of 45 meter high, razor-sharp limestone spikes that tower majestically above the surrounding forest. Recover some of your energy with a simple picnic lunch before you climb back down to Camp 5, where the river in front of the camp will invite you to cool off after this great adventure.
Dinner and overnight at Camp 5.

Day 4:   (B/-/-)
After a simple breakfast, return to the National Park headquarters (expected time of arrival around noon) via the same route as on day 2. Transfer to Mulu airport for your departure flight or to your accommodation for extension stay.


– If the water level in Melinau river is low, certain sections of the river will require passengers to get out of the boat and the boat has to be pushed. Therefore it is recommended to wear trekking sandals or shoes that may get wet.

– The Pinnacle trail is regarded as an extreme climb (not a trek) on a natural route. Man-made assistance comes in the form of vertical steel ladders bolted into the rock faces and ropes. If you suffer from vertigo or fear of heights this is not for you. Also this tour requires a high level of fitness and good health condition!
– This tour is not suitable for children below 16 years of age!
– Domestic flights to and from Mulu are not included. You may find further information and book flights
