The Luangwa River is one of the major tributaries of the Zambezi River, and one of the four biggest rivers of Zambia. The river generally floods in the rainy season (December to March) and then falls considerably in the dry season. It is one of the biggest unaltered rivers in Southern Africa and the 52,000 square kilometres (20,000 sq mi) that make up the surrounding valley are home to abundant wildlife. The Nsefu sector in South Luangwa is known for its Leopard population and intact wilderness.
