Gunung Mulu is Sarawak's first UNESCO World Heritage Site and one of the few big-name parks in Asia where the entry fee is almost an afterthought. A Malaysian pays RM15 for a pass that lasts five days. The money goes on the guided tours, which you cannot skip because the caves are closed to anyone without a park guide, and on getting there, because there is no road.

Everything below comes from mulupark.com, the official site of Borsarmulu Park Management Sdn Bhd, which runs the park, read on 22 September 2026. The tour prices are per person and include the guide, and where stated the boat. They are the same for Malaysians and foreigners; only the park pass has a MyKad rate.

How to choose what to book

Think of Mulu's activities in three tiers.

  • The show caves and walks (RM35 to RM70) are mostly on plankwalks or lit paths and need only reasonable fitness. Deer and Lang Caves, Clearwater and Wind Caves, Fastlane, the Canopy Walk and the Night Walk sit here. Almost everyone does the first three.
  • Adventure caving (RM160 to RM258) means helmets, headlamps and unlit passages. Lagang and Racer are intermediate, for age 12 and up; Clearwater Connection is advanced, for 16 and up, and requires proof of previous wild-cave experience.
  • The multi-day climbs (RM465 and RM660) are the Pinnacles and the Summit of Gunung Mulu itself. Both need a minimum group of three, advance booking and real fitness.

Two things to know before booking anything. The park's cancellation policy is strict: a 50% fee applies to any tour you cancel within 24 hours of departure, and there is no refund once you have left the Park Office, whether the tour stops early for fitness, water levels, sickness or any other reason. And from June to September the park asks visitors to book guides and rooms in advance, because once they are full it cannot help.

What a trip actually costs

A Malaysian couple on a classic three-night trip, doing Deer and Lang, Clearwater and Winds, the Canopy Walk and the Night Walk: RM30 in park passes and RM390 in tours, RM420 in all. Add three nights in a Rainforest Lodge room at the park headquarters (RM370 a night for two) and the total is RM1,530, before flights and food.

The same couple on a budget, two nights in the park's 14-bed hostel at RM80 a bed, doing only Deer and Lang and Clearwater and Winds: RM30 in passes, RM210 in tours and RM320 in beds, RM560 before flights. The bat exodus costs nothing either way.

A foreign couple on the classic trip pays RM60 for passes, so RM1,560, plus RM10 a room a night in Tourism Tax, which the park adds for foreign guests.

Getting there, and the things that catch people out

Mulu can realistically only be reached by air. The park's own page lists daily flights from Miri (30 minutes), Kuching (1 hour 20 minutes) and Kota Kinabalu (55 minutes), and sends you to AirBorneo for the current schedule. Heavy rain occasionally cancels flights, so the park advises a flexible itinerary, especially on the way out. Do not book a tight connection home.

The park's own list is blunt: no banks, no pharmacy, no shopping centres. Bring enough cash for tours booked at headquarters, the park's café and the snack kiosk at the bat observatory. Filming or flying a drone, even for personal use, needs a separate permit from the Sarawak Forestry Corporation in Kuching.

The conservation fees introduced on 1 February 2026 apply on top of everything else: RM20 a visitor for anyone accompanied by a freelance guide or tour operator, an extra RM10 sustainability fee for every visitor to Camp 5, and RM15 for the Summit and Headhunters Trail.

How to pick

With one full day, do Clearwater and Winds in the morning and Deer and Lang in the afternoon, timed so you are at the observatory when the bats leave. With two, add the Canopy Walk at 7am and the Night Walk. Only commit to the Pinnacles if you are genuinely fit and comfortable on ladders at height: the park calls it an extreme climb, not a trek, and says most injuries happen to people who underestimated it.
