Ulu Temburong National Park is a protected area of largely intact lowland and montane rainforest in Brunei’s Temburong District. The park is noted for its primary forest, river valleys and biodiversity.

Visitors come for guided jungle treks, river trips, wildlife observation and elevated canopy viewpoints that provide forest panoramas. Trails and river corridors lead to waterfalls and observation platforms used for birdwatching and nature study.

The park was gazetted as a protected area to conserve one of the few remaining unlogged lowland rainforests in the region and has been managed to limit development and preserve habitat. Conservation initiatives support guided eco-tourism and scientific study.

Ulu Temburong lies in eastern Brunei’s Temburong District, separated from the Brunei-Muara mainland by Brunei Bay and the Malaysian district of Limbang. Access historically required a river transfer from Bandar Seri Begawan and a boat trip into the park.

  • Access logistics: Access typically involves a boat ride from Bandar Seri Begawan followed by trail or river travel into the park, so allow extra time for transfers.
  • Visitor preparation: Prepare for humid rainforest conditions and bring insect repellent and proper footwear for steep trails and muddy paths.

How to Get to Ulu Temburong National Park #

Ulu Temburong National Park is in Brunei’s Temburong District and is commonly visited from Bandar Seri Begawan. Many visitors join organised tours that include a river/boat transfer from Bandar Seri Begawan to park entry points and rainforest trails. Since the opening of the Sultan Haji Omar Ali Saifuddien Bridge, you can also drive from Bandar Seri Begawan into Temburong and follow local roads toward Bangar and the park - final access often still involves a short boat transfer or trekking into the reserve.

Tips for Visiting Ulu Temburong National Park #

  • Book a visit with an authorized tour operator in advance-most day trips depart from Bangar by river boat and include the park guide, permits and transfers you cannot easily arrange on your own.
  • Arrive early in the day for cooler temperatures and better chances of wildlife sightings; the popular canopy walkway and short trails fill up by late morning with day‑trippers.
  • If you want quieter trails and deeper forest access, choose an overnight package or a multi‑day trip rather than a single day visit, which gives access to sections most day visitors miss.
