Gunung Mulu National Park, Sarawak (2000)

A World of Caves, Peaks, and Rainforests

Gunung Mulu National Park, located in Sarawak, Malaysian Borneo, is a UNESCO World Heritage Site renowned for its breathtaking natural beauty and incredible geological significance. Covering approximately 52,864 hectares, the park features one of the world’s most remarkable karst landscapes, housing vast cave systems and unique limestone formations.

Visitors are awed by the Sarawak Chamber, one of the largest known underground chambers in the world, and Deer Cave, famous for its immense size and the dramatic daily flight of millions of bats at dusk. Another iconic sight is the Pinnacles of Gunung Api — razor-sharp limestone spires rising from the lush rainforest, offering a challenging but unforgettable trekking experience.

Gunung Mulu’s ecosystems are rich and diverse, ranging from lowland rainforests to montane forests, supporting a wide variety of flora and fauna, many of which are found nowhere else on Earth. The park not only captivates adventurers and nature lovers but also serves as a significant site for scientific research and conservation.
