Gunung Mulu National Park

Gunung Mulu National Park, near Miri, Sarawak is a UNESCO World Heritage Site that is famous for its extensive  caves systems and most spectacular caves in the World. However only 4 caves are open to public and it can only be visited with the presence of a licensed park guide.

Getting there

The National Park can be reached either by air (multiple flights from Miri) or by boat (ten hour river trip from Miri). To save some time, we decided on flying from Kuching, plus it was actually not that expensive to fly with AirAsia and MASWings.

We flew from KL to Miri (AirAsia) then onwards to Mulu with MASWings. Total journey time was approx half day including transit time.


There are two options: (1) affordable rooms at the National Park HQ or (2) slightly more upmarket (ie high class) rooms at Royal Mulu Resort. Naturally we choose the more affordable room at the Park HQ. The room rate also include breakfast which is handy.

The rooms are very clean and near to the start of the trekking path, which is convenient. I would highly recommend sleeping at the Park HQ.

Be mindful that there is no other accommodation available besides these 2 options. Therefore do plan ahead.


When we arrived at the National Park, we have to register and check-in at the Park HQ. We were also given briefing on various kind of activities we can participate during our stay. To help us decide and plan, we were given the ‘Mulu Discovery Planner’.

The planner shows the various walking path, caving trips (time and cost) and it also allow us to record our choice of activities by the day. This is what we did in our 3 days stay:

  • The Mulu Canopy Skywalk – the longest tree-based walkway in the World (480 metres).
  • Deer & Langs Caves – Spectacular display of stalactites, stalagmites, helictites, shawls and rimstone pools. Deer cave is the biggest show cave at Mulu and has the largest cave passage in the world. It’s a 3km walk along the timber plank from the Park HQ to get to the caves. After visiting the caves, we waited at the Bat Observatory for the famour ‘Bat Exodus’. Any time between 1640 and 1800, millions of bats stream from the cave in a long floating ribbons. It’s am amazing sight.
  • Clearwater Cave & Cave of the Winds – We have to take a boat ride  and climb lots of steep steps to get to the entrance of both caves. From the entrance of the Cave of the Winds, you can feel the cooling winds as you walk through. Water used to flow through these caves, esp for Clearwater Cave which used to have a river flowing through 150km of cave passages in this cave system. At the end of the trip, we were given a few mins to swim in the river water.
  • The Night Shift – Discovering the forest by night. We walked for about 2 hours and saw a lot of night insects and animals.
