It is the largest proclaimed nature reserve in the Johannesburg Metropolitan area and boasts a diversity ranging from large game such as Zebra and Hartebeest to many items of botanical, geological, archaeological, historical and cultural interest.
The reserve is rated by many as a birding hotspot. Despite not having any wetlands of significance, more than 215 bird species have been identified.
Hiking is the main activity in the reserve. The many walking trails are scenic and vary in distance and in the degree of difficulty. A three-hour hike along the flatter areas can be completed by most people and the steeper, more hilly areas can be testing for even the fit.
