Tien Hai Nature Reserve is bordered by the Red River (also called Ba Lat River) to the south, the Lan river to the north and the main sea dike to the west. There are two sandy islands within the nature reserve: Vanh island, which covers 2000 ha and Thu Island, which covers 50 ha. Thu island is situated 4 km from the main land and the intervening intertidal area comprises sand-flats. Vanh island is separated from the mainland by a deep-water channel, the banks of which are covered by mangrove, most of which is included within aquacultural ponds. There is another extensive area of aquacultural ponds on the north bank of the Red River.
