Onderkloof is situated in the historical wine region of Stellenbosch in the Western Cape. The sea and nearest town, Somerset West, are only 6 kilometers away.

The name Onderkloof means “below the valley” and comes from the Pass which leads over the Hottentots Holland Mountains. In earlier years, all goods which have been shipped to and from Cape Town, were transported with ox wagons over these mountains into the countryside. The ruts are still visible today and the pass has become a national monument.
