Introducing Ulu Temburong National Park
It's odd that in a country as manicured and regulated as Brunei, there's still a sizable chunk of true untamed wilderness. Therein lays the appeal of Ulu Temburong National Park, located in the heart of a 500-sq-km area of pristine rainforest covering most of southern Temburong. It's so untouched that 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 for future generations, 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 – so don't forget your swimsuit.
The forests of Ulu Temburong are teeming with life, including as many as 400 kinds of butterfly, but don't count on seeing many vertebrates. The best times to spot birds and animals, in the rainforest and along river banks, are around sunrise and sunset, but you're much more likely to hear hornbills and Bornean gibbons than to see them.
