Malolotja Nature Reserve covers 4,447 acres (18,000 ha) of mountain wilderness on Swaziland's north western border with South Africa. The park includes Ngwenya Mountain, Swaziland's second highest mountain (1829 m), and Malolotja Falls which drop 292 feet (90 metres), the highest in Swaziland. Habitats include short grassland to thick riverine scrub, bushveld and Afromontane forest. Malolotja Nature Reserve adjoins the Songimvelo Game Reserve in South Africa, and together they form the Songimvelo-Malolotja Transboundary Protected Area or Peace Park, which in turn is part of the Lubombo Transfrontier Conservation Area.
