Maliau Basin, Sabah, Malaysia: Hiking along the Maliau River. The acidic tea-coloured Maliau River is actually very clean. The whole Maliau Basin is a single water catchment, drained by one Maliau River only. Borneo's Maliau Basin is among the least explored regions on planet Earth, a caldera of pristine forests, one of the few remaining untouched wilderness areas in the world.
