The Danum Valley Conservation Area is rich in wild life. The rare Sumatran rhinoceros, orangutans, gibbons, mouse deer and bearded pig can all be found here. Some 270 species of birds have been recorded in the area. The Danum Field Research Center is located within the confines of this 440 sq km forest reserve.

It also boasts one of the first eco-resorts, known as the Borneo Rainforest Lodge, which features a restaurant, bar, and comfortable chalets overlooking the Danum River. Jungle treks, river swimming, bird watching, night jungle tours and excursions to nearby logging sites and timber malls are some of the activities offered here.
