The Free State is situated on a succession of flat grassy plains sprinkled with pastureland, resting on a general elevation of 3,800 feet only broken by the occasional hill or kopje. The rich soil and pleasant climate allow for a thriving agricultural industry. The province is high-lying, with almost all land being 1,000 metres above sea level. The Drakensberg and Maluti Mountains foothills raise the terrain to over 2,000 m in the east. The Free State lies in the heart of the Karoo Sequence of rocks, containing shales, mudstones, sandstones and the Drakensberg Basalt forming the youngest capping rocks.
The flats in the south of the reserve provides ideal conditions for large herds of plain game such as black wildebeest and springbok. The ridges, koppies and plains typical of the northern section are home to kudu, red hartebeest, southern white rhinoceros and buffalo. The African wildcat, black wildebeest, zebra, eland, white rhinoceros and wild dog can be seen at the Soetdoring Nature Reserve near Bloemfontein. The South African cheetahs has been reintroduced in the Free State for the first time in June 2013 after a hundred years of regional extinction, at Laohu Valley Reserve near Philippolis.
