The Limietberg Nature Reserve lies in the Du Toitskloof mountains near Paarl, forming a part of the greater Boland mountain range.
The reserve stretches from Franschhoek in the south, eastwards towards Groot Drakenstein, and northwards as far as Voëlvlei dam, covering an area of some 117 000 ha.
The terrain is rugged, with steep kloofs and deep valleys. Du Toits Peak at 1996m is the highest point within the reserve.
Limietberg is an important water catchment for the Breede and Berg Rivers which flow through the reserve, and feed the Wemmershoek, Stettynskloof, Theewaterskloof, Voëlvlei and Berg River dams.
