Mulu National Park is justifiably famous for its limestone karst formations and some of the most spectacular caves on earth. Listed as a World Heritage Site in 2000, the park is dominated by three mountains - Mulu, Api and Benarat - and covers 52,000 hectares of primary rainforest. Four “show caves” can be visited as day trips from park HQ and are accessed by jungle trails, plank walkways or pathways through the caves.
The park’s biodiversity is as impressive as its caves with Mulu containing 15 different types of forest and thousands of species of ferns, fungi, mosses and flowering plants. Mulu is also home to a wide variety of mammals, reptiles, birds, amphibians, fish and insects. In addition to the show caves there are a number of jungle trails and adventure treks available including Gunung Mulu Summit Trek, Pinnacles climb of Gunung Api and the Headhunters’ Trail.
