Welcome to Maliau Basin Conservation Area
The basin, a 25km-wide bowl-shaped depression of rainforest, was unnoticed by the world until a pilot almost crashed into the walls that hem it off in 1947, and is the single best place in Borneo to experience old-growth tropical rainforest. More than that, it is one of the world's great reserves of biodiversity, a dense knot of almost unbelievable genetic richness – more than 2000 types of fauna and flora are found here, with more awaiting discovery. It wasn't until 1988 that an expedition into the basin found a self-contained ecosystem of 12 types of forest and tremendous waterfalls. Maliau Basin attracts a small number of adventurous, hardy trekkers and naturalists per year.
