Gunung Mulu National Park near Miri, Sarawak, Malaysian Borneo, is encompasses of incredible caves and karsts formations in a mountainous equatorial rainforest setting.
Mulu is a very inaccessible area; the only practical way of getting to and from it is by air, mainly from Miri airport. It is possible to travel to the area by riverboat, but it requires a chartered long boat for the last part - and the whole trip by river would take around 12 hours to complete from Miri, while the flight takes only 30 minutes. Two companies offer the flights which are MAS and Hornbill Skyways.
I only have the chance to explore the Deer Cave, Wind Cave, and Clearwater Cave which exposes parts of a long underground river going through the park.
Our first day was a canopy walks from Park Headquarters through a plank walk leads through forest to Dear Cave and Lang’s Cave.
Our second day was exploration by Long Boat to Wind Cave and Clearwater Cave and later to a waterfall as our last journey.
