The Kinabatangan River, with a total length of about 560 kilometers, is the longest river in Sabah and the largest wild animal settlement. Because of the rich natural ecology, many foreign tourists are attracted to live in Bilit or Sukau. Along the river bank there is a chance to see proboscis monkeys, various birds and wild animals. It is also possible to encounter wild orangutans, langurs, gibbons, macaques or Bornean pygmy elephants.
