Bangar is the main town of Temburong, Brunei's eastern district, separated from the rest of the country by a wedge of Malaysian Sarawak. The town itself is tiny — a few shops, a mosque, a couple of places to eat — but it is the gateway to Ulu Temburong National Park, one of the best-preserved patches of primary rainforest in Borneo.
The park's canopy walkway, strung between aluminium towers high above the forest floor, gives dizzying views across unbroken jungle. Getting there involves a longboat ride up the Temburong River and a walk through the forest — the journey is half the experience. Bangar is reached from Bandar Seri Begawan by a scenic speedboat ride through the mangrove-lined Brunei Bay, or via the new Temburong Bridge.
