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.
MASWings , took over the rural air services links, which includes flights in and out of Mulu from Fly Asian Xpress (FAX)], on October 1, 2007.
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.
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.
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.
Most visitors come to Mulu for the caves, but there are also good jungle and mountain trekking options in the area. Guides are obligatory for all cave visits and most treks.
With its 480m of elevated walkway, Mulu's Canopy Skywalk is the world's longest tree based canopy walk.
Most activities can be booked through Park HQ at a fraction of the cost; call ahead or email to ensure there is availability but you will love the quality of guide, as well as the price! 6 days of activities can be completed for the same cost as a 4 day hike through other adventure companies.
- You must qualify on an intermediate cave before you can do the advanced Clearwater connection (awesome activity, do it if you can). The best intermediate cave is Racer as it gives you an idea of the type of activity in Clearwater connection; a few squeezes, lots of mud and ropes to haul yourself up along the terrain.
- This trek is incredible. Start on day 1 by taking a boat up the river (if the river is low you will have to get out and push, wear sandals that can get wet but also stay on your feet - no flip flops) and then a 9 km walk (mostly flat) through the jungle to Camp 5. Be aware that after it rains there are tiny leeches on the leaves, wear long pants. Day 2 is the full hike up the Pinnacles, with a 80-90% incline; doable but challenging, bring lots of water. The hike down is more challenging than up but the ladders and ropes are all in great condition and the guide is well trained.
- Overnight in camp 5 is very rustic. The beds are just foam mattresses on a long wooden board, open to the air with partial walls (when they offer you a mosquito net, take it with you from park HQ) and with limited electricity (bring a headlamp). Quite relaxing to stay in and hear the jungle as you fall asleep.
- If you book through the Park HQ you will need to hike in your own food. Supplies are extremely limited in town and it is advisable to bring your own food from Kuching, Miri or KK (less expensive and more selection). The facilities are basic with hot water, kettles and burners; keep this in mind when choosing food.
- limited creatures found with the exception of stick bugs... lots of those. A nice stroll along the boardwalks and cheap to do.
The Penan community of Batu Bungan sell handicrafts (beads, rottan and basketware) some of which (but not all) they make themselves.
It is incredibly easy to stay outside the park at Mulu. All guesthouses and homestays are within 2km walking distance and offer camping from RM5 and dorms from RM25. This option is not advertised or promoted by the Park since the management of the Park and its accommodation is privately owned. Local accomodation runs their own generator. Power supply only in the evening till midnight.
