The Niassa is a Private Game Reserve in Mozambique in the provinces of Cabo Delgado. The park was established on 01.01.1954 and covers an area of 42 km². The Niassa is a Big Five reserve and offers the possibility of self-drive safaris.
The park borders the Rovuma River in the north, which also forms the border with Tanzania, and is part of the Selous-Niassa ecosystem and connected to the Selous Game Reserve by a so-called "wildlife corridor". It is the largest nature reserve in Mozambique and the third largest game reserve in Africa. Without fences, it borders the Nyerere National Park in Tanzania, so the animals move freely in this huge area.
