Mount Mulu National Park

Mount Mulu National Park is located within the nature reserves of Sarawak, Malaysia, in the fourth and fifth divisions of Borneo in the northern part of Sarawak, near the border with Brunei, covering an area of approximately 53,000 hectares. The park's Mount Mulu stands at 2,377 meters above sea level, making it the second highest peak in East Malaysia. It was designated as a national park in 1975.

The park boasts 344 square kilometers of pristine tropical rainforest; limestone mountain ranges cut through the landscape, with rivers and streams carving out spectacular gorges, karst towers, and cliffs. It is home to the world’s largest cave system, including more than 20 caves, the largest of which has an entrance 2,000 meters wide, 1,000 meters long, and 250 meters high, with a volume of 10–13 million cubic meters, and features a dazzling array of limestone formations. Over 2,000 plant species, 60 mammal species, 200+ bird species, 20+ lizard species, 5,000+ beetle species, and 600 moth species have been identified in Mount Mulu National Park, making it one of the most biologically rich areas in Southeast Asia. Research on the park’s natural environment and the socio-economic patterns of its indigenous peoples began in the 1970s, and in 2000 it was inscribed on the UNESCO World Natural Heritage List.
