The Boland (Afrikaans pronunciation: [ˈbuəlant], meaning "highland"[1]) is a region of the Western Cape province of South Africa, situated to the northeast of Cape Town in the middle and upper courses of the Berg and Breede Rivers, around the Boland Mountains of the central Cape Fold Belt.
It may be understood to extend as far as Malmesbury, Tulbagh, Swellendam, Somerset West, Brackenfell and Durbanville.
This is approximately the area included in the Cape Winelands District Municipality, which was formerly called the Boland District Municipality.
To the southwest lies the Cape Town metropolitan area, to the northwest the Swartland and West Coast, to the northeast the Great Karoo, to the east the Little Karoo, and to the south the Overberg.
The catchment area of the Boland Mountains feeds the Berg, Breede and Riviersonderend rivers, and provides almost the entire water source for Cape Town.
