Gunung Mulu National Park

Gunung Mulu National Park is a UNESCO World Heritage wilderness in Sarawak, famed for vast cave systems, razor limestone pinnacles, and unbroken rainforest. Deer Cave, Clearwater Cave, and the Pinnacles trek reveal geology shaped over millions of years, while evening bat flights from cave mouths are an unforgettable natural spectacle. The park stands among Borneo’s most celebrated conservation landscapes. Visit for guided cave walks, canopy and jungle trails, and a sense of deep time in living forest. It rewards travellers who want more than a quick photo stop—proper wilderness with world-class karst scenery and rare biodiversity. Plan time, permits, and local guides; Mulu is best savoured slowly.
