Sarawak's Bako National Park and Mulu Caves

This activity trip takes in the highlights of Sarawak’s wildlife and stunning natural landscapes. See the sights of cultural Kuching, see semi-wild orangutans in the Semenggoh Rehabilitation centre and set off kayaking through a craggy jungle ravine before staying overnight in the wildlife hotspot of Bako National Park. 

From here transfer to the World Heritage Site of Mulu National Park to explore some of largest caves on earth and trek through pristine primary rainforest. There is an optional additional climb of Gunung Mulu which is a very adventurous trek that rewards the hiker with beautiful views over the rainforest of Sarawak.

Bako National Park

A birders paradise, this park is on the peninsula slightly north of Kuching and although it is not a big park there is a wealth of wildlife to see and many beautiful trails to discover. Encircled by bays and coves and beaches, there is a huge variety of vegetation at Bako and visitors are almost certain to see wildlife like long tailed macaque monkeys, silver leaf monkeys, wild boar and proboscis monkey. 

Bird species commonly seen include the Rufous-backed Kingfisher, Ruddy Kingfisher, Stork-billed Kingfisher, Red-crowned Barbet, Brown Barbet, White-bellied Woodpecker, Black-&-Red Broadbill, Asian Fairy Bluebird, Mangrove Blue Flycatcher, Velvet-fronted Nuthatch, Abbott’s Babbler, White-chested Babbler, Sunda Scops Owl, Oriental Bay Owl and Buffy Fish Owl. 

Mount Mulu National Park

Flying into this park from Kuching, brings the visitor to a special world of waterways and enormous caves which you can visit by boat. Some are show caves, some are adventure caves and they all have their own personality and attractions, including the famous bat exodus every day from the huge Deer Cave. It is a special place to visit, relatively recently discovered and an opportunity to also enjoy kayaking along the quiet rivers which are like green tunnels, and if you are quiet and still, to see and hear the wildlife appear all around you.

We can arrange climbs to the rewarding Mount Mulu in Mulu National Park. At 2376m, this climb will be a great introduction to trekking and climbing in Borneo and is especially memorable for the virgin rainforest views, prolific orchid and pitcher plant diversity, and spectacular summit views. It is quite a tough treks that Borneo has to offer and adds a four days to your trip.

After breakfast, drive about 35 minutes to Bako Village and take a 25-minute boat ride (depending on the tide) to the park situated on a peninsula. Bako is one of the best places in Sarawak to see wildlife in a natural setting. The various types of animals that are commonly spotted at Bako include the proboscis monkeys, silver leaf monkeys, long-tailed macaques, wild boars, monitor lizards and numerous species of birds. Forest types range from mangrove to kerangas (heath forest), tropical swamp vegetation, cliff vegetation and beach vegetation. There are several trails to follow inside the park depending on level of fitness and interest. The park’s coastline is dotted with small bays, coves and beaches.

You will stay overnight in the National Park so take advantage of the best wildlife spotting opportunities at dusk and sunrise.

After breakfast and a hike on one of the trails spotting rare migratory birds and searching for the rare and elusive proboscis monkey, a primate only found in Borneo, return to Kuching and re-check into the Borneo Tribal Lodge for a free afternoon to explore Kuching's winding streets, visit a museum or take a sunset cruise along the river.

Morning flight to Mulu National Park. In the afternoon trek to the entrance of Deer Cave on a 3km plank walkway. Deer Cave has the world's largest cave entrance and is the largest single cave passage in the world - about 120 - 150 m in diameter, or it can fit St. Paul's Cathedral under its massive archway. The cave has a moon-like landscape and from one vantage point, a perfect profile of President Lincoln can be observed. Most evenings at sundown, a spectacular exodus of about 2 million of bats can be observed as they leave the cave in search of food.

Next to Deer Cave is Lang’s Cave. The stalactites and stalagmites inside this cave are representative of the very best limestone formations in the park. Here you’ll wait for the dusk bats exodus. Trek back to the Park HQ at dusk, freshen up and then head to dinner and overnight.

(B, L, D)


A full day exploring Mulu's many waterways and hidden caves. 

Clearwater is Asia’s longest cave at 107km and has its own subterranean river. Wind Cave, which is part of the Clearwater system, is so called due to the cool breeze that is often felt in the narrow parts of the cave. It has many impressive stalactites and stalagmites, flowrocks and rock corals.

Enjoy a picnic lunch and swimming at Clearwater Springs before heading back by longboat to the HQ.
