Mount Mulu, Mountain summit in Sarawak, Malaysia
Mount Mulu is a mountain summit in Sarawak, Malaysia, rising within Mulu National Park and built from layers of sandstone and shale. Its slopes are steep and densely forested, making the peak invisible from below until the final stages of the climb.
The first recorded ascent took place in 1932, led by a local guide named Tama Nilong who had found the route himself. The path he established remains the one climbers follow today.
For the Penan and Berawan communities, the mountain and its forest are deeply familiar territory, not a destination but a place shaped by daily use over generations. Local guides often point out plants and landmarks in ways that show how closely their knowledge is tied to this specific landscape.
The trek typically takes four days and three nights, with set camping spots along the route. A local guide is required, and solid hiking boots along with rain gear are essential given the wet and steep terrain.
Several pitcher plant species found on the upper slopes, including Nepenthes muluensis, grow nowhere else in the world. These carnivorous plants thrive precisely where the soil is poorest, which is why the higher you climb, the more of them you see.
