The Kinabatangan River is the 2nd longest river in Malaysia and made up of tropical lowland forests. Although no longer as extensive as it once was, it remains one of the few areas in Sabah where visitors can still see a large majority of Borneo’s indigenous wildlife in a single area. It is home to proboscis monkeys, langurs, gibbons, orang utan, hornbills, estuarine crocodiles, Bornean pygmy elephants, and the clouded leopard.
