Gunung Mulu National Park
Mulu Caves National Park is home to one of the longest networks of caves in the world. Here lies the world’s largest underground chamber, the Sarawak Chamber, capable of accommodating forty Boeing 747 airplanes.
In Mulu, you will also find the world’s biggest cave passage, 
Deer Cave, which can fit five cathedrals the size of Saint Paul’s in London. Another key attraction is Clear Water Cave, the longest cave in Southeast Asia. The massive caves here are home to millions of bats and cave swiftlets that swarm out into the jungle in great clouds every evening at dusk!
The outdoorsy type will be pleasantly surprised by some of the best examples of tropical limestone weathering in the world, including enormous razor-sharp pinnacles, deep-cut canyons, appropriately named The Pinnacles. There are tough but rewarding multi-day hikes available from the resort. A guide and porter are recommended.
Key Tips
Arrive at the viewing platform in front of Deer Cave by 6 pm to witness the fantastic spectacle of countless bats exiting the cave, headed out for a night's prowl of the jungle. Set your camera to ASA 800 to capture the 'show' sharply as flash won't work in this situation.
How to get there
By Air
Malaysia Airlines operates three daily flights from Miri into Mulu (30 minute flight). Recently, an airline called FAX, which is a subsidiary of Air Asia, has started flying to Mulu as well.
By Boat
You can also take the express boat from Kuala Baram (three hours) to Marudi. From Marudi, take a commercial express boat to Kuala Apoh or Long Panai on the Tutoh River (a tributary of the Baram River). The express departs Marudi at noon daily and returns to Marudi in the early morning of the next day. The trip takes about three hours.
