Gunung Mulu National Park: Caves and Pinnacles
Contents
Gunung Mulu National Park in Sarawak is a UNESCO-listed karst landscape with a vast cave network beneath 52,864 hectares of protected area. Sarawak Chamber is 600 metres long, 415 metres wide and 80 metres high, Deer Cave is the largest known cave passage, and the Clearwater Cave System is the longest cave in Asia at 110 kilometres of mapped passages.[1] Read UNESCO's property description.
Choose a cave visit or a longer trek
For a guided day trip, join the Deer and Lang Caves tour: a 9-kilometre outing that takes about three hours plus time for the bat exodus, with daily departures at 14:00 or 14:30 from park headquarters. It costs MYR 35 per person, including the guide fee.[2] See the Deer and Lang visitor details.
A flat boardwalk of about 3 kilometres leads to the bat observatory in roughly 45 minutes.[2] You cannot enter Deer or Lang Cave without paying beforehand and going with a guide. The bat exodus can start any time after 17:00, depending on the bats.[2] Compare the show-cave options.
The Pinnacles are a bigger commitment. It is a three-day, two-night guided trip: a boat from headquarters, a 9-kilometre walk to Camp 5, then a 2.4-kilometre climb that gains 1,200 metres, with vertical steel ladders bolted into the rock and ropes. The price is MYR 465 per person, including guide, boat and camp fees. The tour starts at 09:15 from headquarters, needs advance booking and runs with a minimum of three people. The climb is not suitable for children aged 16 and under.[3] See the Pinnacles itinerary and booking conditions.

A stay of fewer than five days costs the same, and after five calendar days you need a second ticket. Tours and activities cost extra.[4] Additional charges apply from 1 February 2026: MYR 20 for each visitor accompanied by a freelance guide or tour operator, MYR 10 for Camp 5 visitors, and MYR 15 for Summit and Headhunters Trail visitors.[4] See the park's planning and fee page.
Heavy rain can occasionally cancel flights, so keep your itinerary flexible, especially for onward connections.[4] Book accommodation and guides in advance.[4] There is no ATM in Mulu, so bring enough Malaysian ringgit in cash.[4]
