Accessible through a short flight from the city of Miri, the Gunung Mulu National Park earns its UNESCO World Heritage laurels through its biodiversity.
This 52,684-hectare slice of karst (limestone) tropical forest astounds on multiple levels—some 295km of explored caves, including the largest known cave chamber in the world; over 3,500 plant species, including the rare and extremely pungent Rafflesia; and the soaring Gunung Mulu mountain that gives the park its name.
Villages along the rivers house the Berawan and Penan peoples, who settled here eons ago for the rich hunting and now serve as hosts to visitors. Travelers to Mulu can visit their villages in Long Terawan and Long Iman to browse through the handicraft markets or try their hands at firing the traditional blowpipes.
