The area has always been considered as the breadbasket of the Cape and is largely given to grain farming — mainly wheat. The wheat fields are a major breeding ground for South Africa's national bird, the blue crane. Another important food farmed in the Overberg is fruit with the Elgin Valley being the second largest supplier of fruit in South Africa.
The major towns are Hermanus, Caledon, Bredasdorp and Swellendam and the region includes Cape Agulhas, the southernmost point of Africa. The landscape is dominated by gently to moderately undulating hills enclosed by mountains and the ocean.
The name, derived from Over 't Berg, means "over the (Hottentots-Holland) mountain" and is a reference to the region's location relative to Cape Town.
