Maliau Basin, Sabah's Lost World

Finally, I had the chance to get out from the urban lifestyle and went to The Lost World of Sabah.
Maliau Basin is the single best place in Borneo to experience the wonders of primary tropical forest. More than that, it is one of the world's great reserves of biodiversity, a dense knot of almost unbelievable genetic richness. - Lonely Planet Borneo, 2008
