The Overberg has always been considered 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.
Nestled in the Overberg, one can find the Kogelberg Biosphere Reserve (recognised and registered with UNESCO) populated with a large diversity of flowering plants not found anywhere else in the fynbos biome.
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.
