Gunung Mulu National Park in Baram District of Miri in Sarawak is a UNESCO World Heritage Site that encompasses caves and karst formations in a mountainous equatorial rainforest setting. The park is famous for its caves and the expeditions that have been mounted to explore them and their surrounding rainforest, most notably the Royal Geographical Society Expedition of 1977–1978, which saw over 100 scientists in the field for 15 months. This initiated a series of over 20 expeditions now drawn together as the Mulu Caves Project.
The national park is named after Mount Mulu, the second highest mountain in Sarawak. It covers an area of 52,864 hectares. Gunung Mulu National Park is famous for its limestone karst formations. Features include enormous caves, vast cave networks, rock pinnacles, cliffs and gorges. Mount Mulu is a sandstone mountain rising to 2,376 m (7,795 ft). There are four “show caves” namely the Deer, Lang, Clearwater and Wind caves.
Gunung Mulu National Park has the largest known natural chamber or room – Sarawak Chamber, found in Gua Nasib Bagus. It is 2,300 feet (700 m) long, 1,300 feet (396 m) wide and at least 230 feet (70 m) high. It has been said that the chamber is so big that it could accommodate about 40 Boeing 747s, without overlapping their wings. The nearby Deer Cave is one of the largest single cave passages in the world.
Mulu National Park can be reached either by a 30-minute MasWing ATR-72 flight from Miri, a 90-minute MasWing ATR-72 flight from Kuching, or an 8-hour boat ride from Marudi town.
