Ulu Temburong National Park

The encounter

Species / spectacle: Bornean (grey) gibbons heard and sometimes seen in the canopy, plus hornbills, insects, butterflies and rainforest flora; river fish at swimming stops. Canopy walkway views over intact forest.

How you see it: trek/boat

Typical duration: Full-day trip from Bandar Seri Begawan; visitors typically spend about three to four hours inside the park.

When to go

Visitable year-round; drier stretches ease river levels and trail conditions. Rainforest is wet in all months.

Gibbon calls common year-round at dawn; visual sightings are a matter of luck in any month. Early starts improve chances. (Confirm.)

Best time of day: Early morning for gibbon calls and cooler climbing; canopy walkway best before midday heat. Wildlife quietens by midday.

River levels vary with rainfall, affecting longboat travel and swimming; dawn activity is strongest for wildlife.

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.

Who it suits

Difficulty (1-5): 3 (moderate)

Physical demand: Canopy walkway involves climbing around 800 steps up steel towers to about 50 metres; boardwalks and longboat transfers add activity. Heat and humidity increase effort.

Accessibility & group fit: Suited to reasonably fit visitors and older children; the steep tower climb and longboat access are unsuitable for limited mobility or wheelchairs. Guided-tour format.

Options for a mixed group: Tours keep groups together for safety on the river and walkway; pacing on the climb can vary by individual. (Confirm.)

Permits & responsible travel

Regulation / permits / fees: Access is by guided tour only, with day trips priced around USD 125 per person for small groups; park entry is arranged through licensed operators. Fees volatile (Confirm.).

Guide / crew: Licensed guides and longboat crews are mandatory; independent entry is not permitted. Book through Bandar Seri Begawan operators.

Stay on boardwalks and the walkway, keep noise low near wildlife, and take out all rubbish. Respect the protected reserve and follow guide directions.

Permits, fees and quotas change - confirm before booking.

Safety & hazards

Slippery steps and boardwalks, steep tower climb, longboat river travel and flash-flood risk after rain. Follow crew instructions on the water.

Weather / conditions: Heavy rain raises rivers and can disrupt longboats and the walkway climb; humidity, slippery steps and insects are common. Storms may delay travel.

Guides and operators coordinate response; evacuation is by river to Bangar and on to Bandar Seri Begawan hospitals. Remote access slows rescue. (Confirm.)

Getting there & staying

Access logistics: From Bandar Seri Begawan by road or speedboat to Bangar, overland to Batang Duri, then a longboat up the Temburong River to the park entrance; total transfer takes several hours. (Confirm.)

Accommodation / camping: Eco-lodges and park accommodation near the reserve plus hotels in Bandar Seri Begawan; many visit as a day trip. Overnight stays via operators.

Gear / water / connectivity: Bring water, insect repellent, quick-dry clothing, sturdy shoes and rain gear; connectivity is limited in the park. Carry some cash.

Facilities: Park boardwalks, canopy tower, basic shelters and toilets at facilities; operator lodges provide meals. Amenities limited inside the reserve.

Crowds / solitude: Visitor numbers are limited by the guided-only, river-access format, so it feels uncrowded; peak-season tours can fill. Early departures help.

Operators & guiding

Nearby operators / hubs: Bandar Seri Begawan is the hub with licensed Temburong operators; Bangar and Batang Duri are transfer points. (Confirm.)

Guided trips / outfitters: Brunei-based operators such as Borneo Guide and Sumbiling-linked eco-tour outfits run Ulu Temburong day and overnight trips. Verify current offerings.
