Kloof, meaning gorge, is a small, upper-income town in KwaZulu-Natal, South Africa and is now a suburb of eThekwini . It is a mostly English-speaking area and forms part of the route of the annual Comrades Marathon, run between Pietermaritzburg and Durban.
A stream known as Molweni (stream of high cliffs) cuts a deep ravine in one part of Kloof. This ravine is the 4.47 square kilometre Krantzkloof Nature Reserve. The town is also home to several state and private schools including the prestigious St. Mary's Diocesan School for Girls. Kloof starts from Field's Hill and borders Hillcrest with the M13 freeway intersecting it.
It also features several shopping malls and the Kloof Country Club.
