The easternmost part of Brunei is the Temburong District, which is separated from the capital and the three other Bruneian provinces by the Malaysian state of Sarawak. The Temburong District is rich in unspoiled natural heritage, including the Ulu Temburong National Park (formerly the Batu Apoi Forest Reserve). Here the magnificence of Borneo's lowland rainforests can be truly experienced. Botanically the area is possessed of astounding diversity, however the casual visitor in search of birds or mammals is likely to be disappointed by the apparent lack of fauna. In fact the forests teem with wildlife, but these creatures are invariably shy and are quick to avoid human contact.It's also a great place to disappear for a few days away from faxes and phones. Enjoy the rainforest wilderness, swim in warm mountain streams, hike to an isolated waterfall, get wet in an afternoon rainstorm and wake each morning to the sounds of nature's jungle orchestra.The Ulu Temburong National Park is a special place. Preserved, untouched and with a variety of activity and interest options, it's definitely a highlight of every visit to Brunei.
