Site description The northern boundary of this reserve lies 13 km south-west of Harrismith, while the southern edge lies along the border with KwaZulu-Natal, just west of Oliviershoek Pass. Most of the eastern boundary runs along the Free State section of the road (R74) through the pass. The reserve lies in the grassland and alpine belt between 1,700 and 2,328 m, and consists of rolling sour grassland surrounding the state-owned Sterkfontein Dam, which receives most of its water from the Tugela river. The vegetation is primarily high-altitude montane grassland. The western portion of the reserve includes part of the northern end of the ‘Little Drakensberg’ section of the escarpment, holding cave sandstone cliffs that are dissected by streams to form valleys and gorges. High-altitude shrubs form a heath of Protea, Erica, Chrysocoma and Helichrysum. Stands of Leucosidea occur on some of the slopes and small patches of Afromontane forest are found in a few gorges.
