By road
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.
By plane
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.
