Tankwa Karoo National Park is a national park in South Africa. The park lies about 70 km due west of Sutherland near the border of the Northern Cape and Western Cape, in one of the most arid regions of South Africa, with areas receiving less than 100 mm of average annual precipitation, moisture-bearing clouds from the Atlantic Ocean being largely stopped by the Cederberg mountains. Other low areas receive little more, as the Roodewerf station (coordinates: S32°14’27.9” E20°05’44.5”) with 180 mm of mean annual rainfall. In the hottest areas of the park, the mean maximum temperature in January is 38.9 °C, and in July the mean minimum temperature ranges from about 5 to 7 °C. Before this Park's proclamation, the only protected area of Succulent Karoo was the 2 square kilometre patch of the Gamkaberg Nature Reserve. Succulent Karoo has, together with the Cape Floral Kingdom, been declared a Biodiversity Hotspot by Conservation International.Tankwa's area has been increased from an initial 260 to 1436 km2. It is bounded on the east by the Roggeveld Mountains, on the west by the Cederberg, to the north by the Kouebokkeveld Mountains and on the south by the scattered foothills of the Koedoesberge and Klein Roggeveld Mountains, and the Tankwa River. The park's headquarters are located at Roodewerf (GPS coordinates: S 32° 14’ 27.9” E 20° 5’ 44.5”). Distances from the nearest towns to the park's headquarters are: Ceres (180 km), Sutherland (120 km), Calvinia (110 km) and Middelpos (52 km).
