Ou Kaapse Weg (Afrikaans for Old Cape Way), numbered as route M64, is a mountain pass in the Cape Peninsula that connects the Southern Suburbs of Cape Town with the Fish Hoek Valley.
It traverses the Steenberg mountains and passes through the Silvermine Nature Reserve.
Ou Kaapse Weg is one of three routes to the Fish Hoek Valley: the others are Chapman's Peak Drive along the Atlantic coast and Main Road along the False Bay coast.
Despite its name, the pass was only constructed in 1968, by the Divisional Council of the Cape.
