Kgalagadi Transfrontier Park is a large wildlife preserve and conservation area in southern Africa. The park straddles the border between South Africa and Botswana and comprises two adjoining national parks:
Kalahari Gemsbok National Park in South Africa
Gemsbok National Park in Botswana
The total area of the park is 38,000 square kilometres (15,000 sq mi). Approximately three-quarters of the park lies in Botswana and one-quarter in South Africa.
Kgalagadi means place of thirst. The park is located largely within the southern Kalahari Desert. The terrain consists of red sand dunes, sparse vegetation, occasional trees, and the dry riverbeds of the Nossob and Auob Rivers. The rivers are said to flow only about once per century. However, water flows underground and provides life for grass and camelthorn trees growing in the river beds. The rivers may flow briefly after large thunderstorms, a cause for celebration among the wildlife, who will flock to the river beds and slake their eternal thirst.
