Twee Rivieren (or Two Rivers) is the south entrance to the Kgalagadi Transfrontier Park, and the only entrance from the South African side. This is where the Auob and Nossob rivers meet.

The Nossob river road runs along the river north to south, marking the boarder between South African and Botswana.

The Auob river road runs north west to south east, right up to Mata Mata camp which also serves as the Namibian boarder post.

Twee Rivieren camp is the most equiped camp in the park, offering petrol station, large new welcome office, well stocked shop, restaurant, as well as camping and challet accommodation.
