With its highest elevation of 1 088 meters above sea level it is a natural landmark between the towns of Caledon and Greyton in the Western Cape Province of South Africa.

This inselberg is situated within the Cape Floral Region, one of the epicentres of plant diversity in the world. As a micro cosmos of the Cape Floral Region, the mountain and its ecosystem are of international significance.

The mountain is surrounded by commercial grain and livestock farmland and is the catchment of three rivers.
