Ninh Thuận Province
Phước Bình National Park is contiguous with Bi Doup – Nui Ba National Park in Lâm Đồng Province to the west, and provides an important biodiversity corridor and core habitat as well as being an area of significant cultural history to the local ethnic communities. It also plays an essential role in protecting the Cai River watershed. This is the largest river in Ninh Thuận province, and provides water to all of Ninh Thuận Province, one of Vietnam's most arid regions.
