Against the backdrop of the magnificent Witpoortjie waterfall, this Garden covers almost 300 hectares and consists of both landscaped and natural veld areas. This Botanical Garden was founded in 1982, but has been a popular venue for outings since the 1800's. The Garden has been voted the best picnic spot in Gauteng for 5 years in a row.

The natural vegetation of the area is known as the 'Rocky Highveld Grassland' and consists of a mosaic of grassland and savanna, with dense bush in kloofs and along streams. The variety of habitats accommodates over 600 naturally occurring plant species.

The Garden is home to an abundance of wildlife with over 220 birds species recorded on site. There are also a number of reptiles and small mammals, including small antelope and jackals, which occur naturally in the Nature Reserve.
