Ulu Temburong National Park

Ulu Temburong National Park, located in the heart of a 500-sq-km area of pristine rainforest covering most of southern Temburong, is a highlight of a visit to Brunei. It's odd that a small country such as Brunei should contain such a sizeable chunk of true untamed wilderness. Only about 1 sq km of the park is accessible to tourists, who are only admitted as part of guided-tour packages. To protect it, the rest is off-limits to everyone except scientists, who flock here from around the world. Permitted activities include a canopy walk, some short jungle walks and swimming in the cool mountain waters of Sungai Temburong.
