Borneo’s natural heart is a fantasy-land of primeval forests spread over a spine of mountains in Borneo’s hinterland – the forest here is one of largest extant tracts of rainforest in Southeast Asia. Trekkers will find a fascinating world of glorious nature, and the strong sense of culture – the mountains are home to the longhouse-dwelling Kelabit people, as well as the Penan, a band of hunters and gatherers – makes a trip to the Kelabit Highlands all the more rewarding. By travelling with Pepper Mountains, travellers have the opportunity to lodge in a longhouse, soaking up the wonderfully egalitarian culture of the longhouse, and also join a Penan on a hunt with blowpipe in the forest – find out more at Hornbill Trails page.
