Tasek Merimbun Heritage Park

‘Tasek Merimbun (Translation: Merimbun Lake) Heritage Park’ is a wildlife sanctuary, a conservation spot for flora and fauna, a recreational center, and a venue for research and education. It is the first to be declared a national park in Brunei Darussalam. The 7,800-hectare park was also declared an ASEAN Heritage Park on 29 November 1984, marking a significant era in its history. With this recognition, the government earmarked funds in the 6th National Development Plan for developing facilities at Tasek Merimbun to establish a national park that would incorporate extensive forest areas adjacent to the lake. The Park encloses Brunei's largest lake, Tasek Merimbun, and a number of small rivers feeding into the lake.

Tasek Merimbun is part of a geological formation that was uplifted from a shallow sea about 7 million years ago. Home to many species of flora and fauna, it is a kind of low depression surrounded by swamps as opposed to being a typical lake. The water is black due to the presence of peat i.e. fermentation of plant vegetative materials that feed into the lake through the peat swamp. Tasek Merimbun was declared as Brunei's National Heritage Park in 1967 and later on declared as an ASEAN Heritage Park in 1984. This park is under the management of Brunei Museums Department.
