Gunung Mulu National Park
Lying just below the equator in Borneo’s Sarawak state, Gunung Mulu National Park covers 30 square kilometres of tropical rainforest. Although the jungle is home to a vast range of plant life and birdlife, it is the UNESCO listed limestone caves that extend beneath the forest that are the real draw for many visitors.
Accessible only by plane, Gunung Mulu National Park, named after the second highest mountain in Sarawak, Mount Mulu, is a UNESCO World Heritage Site. One of the most isolated national parks in Borneo, those who make the journey are rewarded with record-breaking cave systems and spectacular karst formations in a mountainous equatorial rainforest setting.
The underground caverns of Mulu are the biggest on earth, revealing a mystical subterranean world of stalactites and stalagmites, and crystal-clear swimming holes. Equally as spectacular are the otherworldly Pinnacles - vast shards of limestone that soar upwards through the undergrowth, from the sides of Gunung Api (or “fire mountain”). One of Mulu’s crowning glories is a visit to Lang’s Cave and Deer Cave at sunset to witness the daily exodus of bats spiralling into the sky in search of good. Other popular caves include Clearwater Cave, Asia’s longest cave measuring around 100 kilometres in length and the Wind Cave, both reached by a leisurely boat journey along the Melinau River.
Although the cave themselves support their own unique ecosystem, the five million year old jungles of Gunung Mulu National Park is home for an array of wildlife, including gibbons, bats, frogs and birdlife which can be spotted on a number of trekking trails in the park. More adventurous visitors may choose to climb the towering Mount Gunung which dominates the landscape, or perhaps try a more challenging trek to view the Pinnacles, a series of 45-metre-high limestone spikes.
