On the southern border of Gauteng Province, this vast 19,000 hectare nature reserve is also an important area of archaeological research with the remnants of an ancient pre-colonial Tswana city recently discovered in the area. Named after the sugarbush (suikerbos), the reserve hosts meandering hiking trails that snake over the Suikerbosrand mountain range as well as a 60km tarred self-drive / cycling route that traverses the rolling hills taking in several dams and birding hides.

Day hikers can choose from the 11km Bokmakiere trail (make sure to leave very early, the area gets very hot around midday), the easy 4.5km Cheetah trail or the wheelchair-accessible 1km Toktokkie trail. The reserve is also popular for its overnight and multiple day hiking trails which make use of remote hikers cottages scattered through the reserve. Overnight trails should be tackled in a group (maximum ten hikers).
