Stellenbosch lies within the Cape Fold Belt Mountains, a long mountain chain that extends 700 km from Port Elizabeth running parallel to the coast to Cape Town, where it takes a sharp 90 degree turn to continue 150 km north of Cape Town as the Cederberg Mountains.  This mountain belt is believed to be the remnant of pre-Pangean tectonic plate collision.

The area of South Africa rests on the African Plate, between divergent plate boundaries in the Atlantic and Indian Oceans.  Here it appears that the predominant geological device is the African superswell, believed to have started between 5 and 30 mya, a mantle plume that continues to push up the height of Southern Africa.

Stellenbosch Mountain, Simonsberg Mountain, Drakenstein Mountains, and the Jonkershoek Mountains bound Stellenbosch directly on the South and South East.  The Drakenstein Mountains are actually two mountain ranges, the Groot and the Klein Drakenstein Mountains.
