One of UNESCO’s World Heritage Sites in Malaysia, the Mulu National Park, with its karst formations in its mountainous equatorial rainforest setting, is the most studied area of tropical karst in the world.

 

Cited as an outstanding example of the world’s geological history, the national park boasts one of the longest chains of caves in the world, as well as being the home for the Sarawak Chamber – the largest natural underground chamber that is huge enough to fit a total of 40 Boeing 747 airplanes!

With the abundance of tropical rainforest in the area, sandstone pinnacles and limestones are able to form through the chain of mountains and caves – consisting of Mount Api, Mount Benerat, Mount Buda, and the dominating Mount Mulu. One of the most well-known sites of the National Park is the Melinau Limestone Formation, portraying its remarkable concentration of caves, a subterranean of huge chambers, and massive flowing underground rivers. Meanwhile, the Garden of Eden showcases one of the world’s finest karst collapse, with its blade-like , sharp pinnacles of limestone; located at Mount Api.
