Limpopo province consists of the vast Lowveld plain, which is interrupted by several mountain ranges rising out of the Highveld plateau in the province’s south and centre. Among these ranges are the forested Soutpans Mountains, which extend about 80 miles (130 km) from east to west. The Water Mountains in the southwest rise to more than 6,500 feet (2,000 metres) and are densely covered with thorn trees and shrubs. The Lowveld extends across the eastern, northern, and western parts of the province and is a subtropical parkland with mopane (mopani) and baobab trees. The Limpopo River forms the province’s northern and western borders. The Great Limpopo Transfrontier Park, of which Kruger National Park is part, lies along the eastern border. The northern part of the province has a hot, subtropical climate with 12 to 20 inches (300 to 500 mm) of precipitation annually. The southern mountains have a more temperate climate with about 30 inches (760 mm) of precipitation yearly.
