Covering 959 103 ha, this park is the result of the 1999 merger of Botswana's Gemsbok National Park and South Africa's Kalahari Gemsbok National Park. The first cross-frontier nature reserve in Africa, it is the fruit of a project initiated by Nelson Mandela, the Peace Parks. On the South African side, two routes follow the course of the dried-up Auob and Nossob rivers, the latter forming the frontier with Botswana. The best time to spot wildlife is between February and May.
