Getting There and Around in Mulu Caves
Part of the Mulu Caves travel guide — see every topic in All Mulu Caves Guides.
Gunung Mulu National Park has no road connection. Access is by air to the park's own small airstrip, served by turboprop aircraft from Miri, Kota Kinabalu and Kuching, or by a multi-day river and overland journey that almost nobody takes. That single fact shapes everything about a Mulu trip: the flights are small and limited, baggage allowances are tight, cancellations happen in bad weather, and once you are there everything is walked or reached by longboat.
Flying in
MASwings and connecting services operate turboprop flights to Mulu from Miri, with connections from Kota Kinabalu and Kuching. Flights are short — around thirty minutes from Miri — and capacity is limited, so book well ahead, particularly in the peak months. Baggage allowances on the small aircraft are strictly enforced and lower than on jets. Weather cancellations occur and there is no alternative when they do, which is a strong argument for building a buffer day before any onward international connection.
The river route
Mulu can be reached overland and by river from Miri via Kuala Baram, Marudi and Long Terawan by express boat and longboat, taking a full day or more depending on water levels and connections, and it is genuinely uncertain in low water. Very few visitors do it. The Headhunters' Trail, which runs between Camp 5 in the park and Limbang via a portage and a longboat down the Terikan river, is the other overland option and is done as a guided three-to-four-day trek in either direction.
Inside the park
Everything within the park is on foot or by longboat. Park headquarters, the accommodation and the airstrip are within walking distance of each other. Deer and Lang caves are a three-kilometre boardwalk. Clearwater and Wind caves are a longboat up the Melinau river. Camp 5, for the Pinnacles, is a longboat plus a walk. Boat costs are charged per boat and shared, so joining others matters. There are no vehicles and no roads beyond the airstrip apron.
Practicalities
Book flights, accommodation and every activity together and well in advance — cave tours, the skywalk and the Pinnacles all have caps and all fill. Bring cash: there is no ATM in the park and card facilities are limited. There is a small shop with basics and no pharmacy. Pack for constant rain and constant humidity, and pack light because of the baggage limits. And note that Sarawak has its own immigration control, so arriving from peninsular Malaysia involves a passport check.
