The Pilanesberg (formerly Pilandsberg) is a mountain in the North West Province, South Africa. The mountain is an ancient volcanic structure, circular in shape, that rises from flat surrounding plains. It is formed by three concentric ridges or rings of hills, of which the outermost has a diameter of about 24 km. The Pilanesberg is located 100 km to the northwest of Pretoria and is for the greater part enclosed in a protected area known as Pilanesberg Game Reserve.
Although geographically located within the Witwatersrand range, the mountain is geologically part of a feature known as the Pilanesberg Alkaline Ring Complex. It is a vast circular crater of a very ancient extinct volcano that last erupted some 1,200 million years ago.
The Pilanesberg is one of the largest volcanic complexes of its type, there are few similar alkaline volcanic structures in the world. Different types of syenites, including a number of rare minerals, occur in the crater area.
