Mount Mulu

Mulu, Sarawak, Malaysia

---

Mount Mulu rises as the prominent 2,376-meter sandstone pinnacle dominating Gunung Mulu National Park in Sarawak's Mulu region, Malaysia, second-highest in the state after Mount Murud and central to a UNESCO World Heritage site famed for its karst landscapes, over 295 kilometers of explored caves like the colossal Sarawak Chamber, and extraordinary biodiversity in ancient rainforests exceeding 130 million years old.

This rugged peak, shrouded in mossy montane forests, draws expert trekkers via challenging multi-day routes from park headquarters involving river crossings, steep ascents past limestone pinnacles, and camps amid pygmy squirrels, hornbills, and rare clouded leopards, offering panoramic vistas of razor-sharp ridges and the Melinau Gorge. 

Accessible mainly by flights to Mulu Airport followed by boat transfers, it epitomizes Borneo's wild interior, blending extreme geology with ecosystems hosting millions of bats emerging at dusk from Deer and Lang Caves below.
