Sabah’s largest waterway is one of only two regions in the world which are inhabited by ten species of primate, and is Borneo’s most popular destination for tourists hoping to catch a glimpse of a wild orangutan.

Most visitors will opt to cruise down the river, combined with the odd trek and overnight stay in a jungle-fringed campground. The river itself is home to freshwater sharks and crocodiles, but If you’re very lucky, you might spot a Bornean elephant on the banks.

The area is also home to the Kinabatangan Orangutan Conservation Project. Although not a tourist-oriented enterprise like Sepilok, the centre may help you source guides should you wish to search for wild orangutans.
