Gunung Mulu National Park
Archaeological evidence from excavations in Cave of the Winds indicate that the cave was used for burial between 1500 and 3000 years ago. In 1977-78 the Royal Geographical Society/Sarawak Government organized a major expedition and survey of the area. An account of the expedition results, environment and biota was published in July 1982 in The Sarawak Museum Journal (Vol.XXX No 51, Special Issue No.2). In 2000 UNESCO inscribed Gunung Mulu National Park on the World Heritage List. Today it is one of Sarawak's most popular travel destinations.
LandscapeNamed after the 2,377m Mount Mulu (Gunung Mulu), the park is famed for its limestone karst formations both above ground and underground. The massive cave systems, which contain the 12 million cubic meter Sarawak Chamber (the world's largest), are still in the process of being mapped. Clearwater Cave at 151 km (Feb 2007) is the 10th longest cave in the world.
The limestones belong to the Melinau Limestone Formation and are estimated to be 4000 to 5000m thick. In the south-east of Mulu Park sandstones are dominant. The hightest relief in the region (Gunung Mulu) is located in these sandstones. Mulu's landforms are outstanding examples of erosional processes on both of these rock types (limestones and sandstones). Among the most remarkable karst features are the world's finest example of a karst collapse (The Garden of Eden) and the sharp pointed bladed limestone Pinnacles, some of which are 45m high on the northern end of Gunung Api. There are also numerous examples of cone karst and tower karst. Another interesting feature of the landscape is the drainage through deeply incised gorges (Sungai Melinau at Melinau Gorge and Sungai Medalam to the north) in the limestones.
Flora and fauna
If you are staying at any homestays or within the park... Do not take the 5RM taxi ride, it is under one kilometer away. You can walk to the park junction road in 5 minutes and then it is another 500M to the park entrance. Only take the ride if you are staying at Mulu Resort as it is another 1.5KM down the road.
Gunung Mulu National Park has a small airport (code: MZV) which actually lies just outside the national park boundary. Most tour operators pick up passengers from the airport and bring them to their respective accommodations. Independent travellers can either thumb a lift from these operators or take a boat ride to Park Headquarters.

- To/from Kota Kinabalu: MASWings runs one flight daily between Kota Kinabalu and Mulu via Miri and direct.
Note that flights in and out of Mulu are often delayed or cancelled because visibility is often affected by the weather. Plan connections to and from Mulu accordingly.
From Airport to Mulu Park HQ, either take minivan (cost RM 5-6 per person each way) or walk for 1.5km. Directions are signposted.
This option is certainly for the more adventurous. In fact, by land is a bit of a misnomer because this option usually requires a combination of going by road, boats and maybe even some hiking.
- To/From Miri: You need to go by road to Kuala Baram along the Miri-Brunei border road (see Miri page for bus connections), then taking a boat up the Baram River to Marudi. Here, you have to take a series of boats up the Tutoh River to reach Gunung Mulu National Park. The Miri-Marudi leg can also be cover by plane. See Miri page for flight details.
- To/From Limbang: This option basically requires you to hike the Headhunter's Trail. See details of the trek under the "Do" section below. There are no longer flights between Mulu and Limbang.
It is possible to reach Mulu by river. From Miri travel by road to Kuala Baram. From there take scheduled river ferry to Marudi. From Marudi take river ferry to Long Terawan (does not operate daily). From Long Terawan charter a long boat to travel up the Tutoh river to Mulu. The whole journey can take from one to several days depending on the connections.
To get into the park you must register at the Park HQ office and buy the five-day-pass for 30 RM per person. To enter any caves you must have a Licensed Park Guide or join a guided group (fees starting from 20RM p.P.).
There is only one road in Mulu. It runs from Royal Mulu Resort to the settlement of Batu Bungan, passing Mulu airport (approx 5km). There are very few vehicles. To get around you can travel by longboat on the Melinau river which runs along the northern boundary of the park, and on the Tutoh river into which the Melinau flows. The park maintains a network of trails to the key sites. The most frequently used trails are plankwalks. Other trails are cemented, or improved with gravels. Some trails (Mulu summit trail) are wild and a guide is needed just to find them.
It is common to hire a guide during your stay in the park. Guides will take care of transportation, accommodation, food and guide you through the jungle. It's strongly recommended to use only Licensed Park Guides. It's for your safety and security. Upon payment you shall receive invoice from the guide all included listing the services.
