The Hills cover an area of about 3100 km² (1200 sq mi), of which 424 km² (164 sq mi) is National Park, the remainder being largely communal land and a small proportion of commercial farmland. The park extends along the Thuli, Mtshelele, Maleme and Mpopoma river valleys. Part of the national park is set aside as a 100 km² (39 sq mi) game park, which has been stocked with game including the white rhinoceros. The highest point in the hills is the promontory named Gulati (1549 m; 5082 ft) just outside the north-eastern corner of the park.
