Visit Mulu National Park, Borneo

Under the national park’s blanket of jungle can be found the world’s largest limestone cave system, dominated by the towering Gunung Mulu.

The area is so isolated that it is accessible only by light aircraft and, once in the park, exploration is on foot or by boat.

Cave systems

A highlight is to follow the labyrinthine passages of Clearwater Cave, perhaps swimming in its pellucid waters, or to visit Lang Cave or Deer Cave at dusk to witness the bats emerging in their shadowy hordes.

Wildlife of Mulu National Park

The park has been estimated to be at least five million years old and, with its soaring peaks and dense forest, it seems to defy time. The forest itself may seem peaceful, but the silence is often broken by the sounds of the gibbons, cicada, hornbills, bats and frogs, while in the steamy heat you can almost hear the creaking, as 8,000 species of plants and trees edge their way to a distant sky.
