Sarawak's Mulu Caves

This activity packed trip takes in the highlights of Sarawak’s wildlife and stunning natural landscapes. See the sights of cultural Kuching, see semi-wild Orang Utans 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, you’ll visit the World Heritage Site, Mulu National Park, to explore some of largest caves on earth and trek through pristine primary rainforests.

Sarawak- Off The Beaten Track Additions

If this isn't enough, we have two optional four day adventures for the more active traveller looking to delve deep into Borneo's interior.

5 Day Penan Tribe Adventure

From Mulu National Park we can arrange 5 day treks to the remote Penan Tribe in the Upper Baram region in Sarawak. You will have the chance to experience life with one the last nomadic tribes in the world, while trekking to hidden waterfalls and learning traditional jungle survival skills.

4 Day Mount Mulu Summit

Alternatively, we arrange climbs to the little known yet rewarding Mount Mulu in Mulu National Park. At 2,376m, 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. This is a near 50 km round trip and is one of the toughest treks that Borneo has to offer.

Sarawak Mulu Caves Detailed Itinerary








Arrive into Kuching and transfer to the Borneo Tribal Lodge for your first group meeting with your tour leader. You will have a free afternoon and evening to explore the lovely cultural sights and Chinese colonial architecture of Sarawak's capital city.




An early start to travel to the Semenggoh Orang Utan Centre  to see these semi-wild rescue animals on their feeding platform at 9am. From here you will travel to the Semadang River to embark on an afternoon of kayaking through craggy ravines covered in dense rainforest before returning to Kuching.

(B, L)




After breakfast, meet your pickup from your hotel and drive about 35 minutes to Bako Village. From the village, you will 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.

(B, L, D)




Following breakfast, depart for a final 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 after lunch. Please note schedule may depend on tide.

On arrival in Kuching you will re-check into the Borneo Tribal Lodge for a free afternoon to explore Kuching's little winding streets, visit a museum or take a sunset cruise along the river.

(B, L)




After breakfast, check out of the hotel and take your morning flight to Mulu National Park.

 This afternoon, you will treks 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.

(B, L, D)




 After breakfast, you will check out of Mulu and the trip finishes.

From here, you can fly back to Kuching, fly to Kota Kinabalu in Sabah, or join one of our four day Sarawak extensions to the remote Penan Tribe, or the summit of Mount Mulu!
