Witsand Nature Reserve () is located in Northern Cape, South Africa, and covers 3,500 hectares. The reserve is 80 km southwest of Postmasburg and 59 km northeast of Groblershoop. The reserve is dominated by sand dunes on a plateau around 1,200 m above sea level. Singing sand can be found here, a phenomenon in which during the dry summer months, a roar can be heard while walking over the sands. Surroundings 70 km north of Witsand is Postmasburg, best known as a center of manganese, asbestos, and diamond mining. Gatkoppies Mine, 5 km north of Postmasburg, is a notable archaeological site. Excavations here prove that the Khoisan were mining here as early as the year 700 C.E. They used a red powder from the iron ore to anoint their faces and bodies, known as blinkklip or hematite.
