Rising from the beautiful Drakensberg Mountains in Lesotho, forming part of the international border between South Africa and Namibia, the Orange River is the longest river in South Africa. The Orange River Basin extends into Namibia and northern Botswana. The river snakes its way through one of Southern Africa’s harshest environments bringing life to an area of sheer rugged beauty. Aside from vineyards in the desert the river also creates a mobile playground from which to explore the area. This spectacular river created the diamond dune fields along Namibia's coast, by washing diamonds downstream from the Kimberly region over millions of years. Visitors can look forward to excellent whitewater rafting, canoeing, and kayaking, as well as wonderful river cruises which allow excellent views of the surroundings.
