Mulu

Mulu generally refers to Gunung Mulu National Park, a protected area in Sarawak, Malaysia on the island of Borneo. The park lies in the Miri Division and covers roughly 52,000 hectares, preserving a dramatic karst limestone landscape set within tropical rainforest.

Geography and features include towering limestone karst formations, the Gunung Mulu massif, and a landscape shaped by ancient limestone cliffs and caves. The park is renowned for its cave networks and for the Pinnacles, a jagged line of limestone spires that rise above the forest and are reachable by a multi-hour trek.

Caves and cave systems are among the park’s most notable features. Gunung Mulu National Park hosts extensive cave complexes, including the Clearwater Cave system, Deer Cave, Lang Cave, and Wind Cave. Deer Cave is famous for its enormous bat colony, while Sarawak Chamber within the park is one of the largest known cave chambers by area, illustrating the size and complexity of the underground networks.

History and status: The area was designated Gunung Mulu National Park in 1974 and was inscribed as a UNESCO World Heritage Site in 2000 in recognition of its extraordinary karst landscapes, cave systems, and biodiversity. The site highlights the scientific and ecological significance of the region and its relatively intact tropical rainforest.

Access and conservation: The park is administered by the Sarawak Parks Corporation. Conservation efforts focus on protecting cave ecosystems and rainforest habitats, while tourism is supported by guided treks, wildlife experiences, and access via Mulu Airport for visitors seeking to explore the park’s natural wonders.
