Olifantsvlei Nature Reserve

The Olifantsvlei Nature Reserve is a large section of protected land in Johannesburg South. It was designated in 1957 in an area of 2043.27 ha. A wetland, part of the Klip River, runs along its southern border. The reserve lies adjacent to Lenasia, alongside the R554. The Golden Highway (R553) and N1 roads vertically divide it into three parts. On its northern border, it lies beneath the towns of Eldorado Park, Nancefield, Devland and Naturena (from west to east). It contains the Olifantsvlei Cemetery, Johannesburg Water's Olifantsvlei Wastewater Treatment Works and Bushkoppies Wastewater Treatment Works. Nearby is the Klipriviersberg Nature Reserve.
