About a million people live in the Northern Cape on 361 830km² of land (which makes it South Africa's most sparsely populated province). The mother-tongue of the majority of Northern Capers is Afrikaans (Other first languages are Setswana, isiXhosa & English). In most places you will be able to find people who can speak English.
San rock paintings can be found in the whole of the Northern Cape, but the area along the Orange and Vaal rivers is especially rich in their engravings (painted while they were in a trance state). True San (Bushman) people live in the Kalahari area, the last of this ancient civilisation. A good collection of San artwork is housed at Kimberley's McGregor Museum.
