Nyanga National Park lies in the north of Zimbabwe's Eastern Highlands and contains the highest land in Zimbabwe, with green hills and perennial rivers. Most of its terrain consists of rolling downland, sometimes lightly wooded, lying at altitudes between 1,800–2,593 meters. Mount Nyangani, the highest point in Zimbabwe, lies in the centre of the park and Mutarazi Falls, Zimbabwe's highest waterfall, is in the south of the park. Nyanga National park incorporates the former Mutarazi Falls National Park on its southern boundary. The vegetation of Nyanga is part of the Eastern Zimbabwe montane forest-grassland mosaic, within the montane grasslands and shrub lands eco region. The rainforest is found mainly on the eastern slopes, as well as in the steeper valleys on west-facing slopes. It is dominated by Syzygium. Copses of Mulanje cypress survive in areas that are safe from fire.
Mount Nyangani is situated in Nyanga National Park, which is in Nyanga Province. The mountain is located at a distance of around 170 miles or 275 km southeast of Harare, the Zimbabwean capital. The height of Mount Nyangani is 8,504 feet (2,592 m). The peak of the mountain is located on top of a little projection of stone about 40 m over the bordering region. Flora on the mountain mostly consists of heaths, evergreen trees, and grassland. Precipitation in this area is quite high (approximately 2,200 mm every year) but extensive periods of arid climate take place throughout the winter season of May to August. Because of the comparatively low elevation and humid climate, snowfall is quite scarce in this area. The last snowfall was registered in the month of August 1935.
A wildlife checklist compiled over several years reveals a remarkable diversity of mammals, including occasional sightings of species such as buffalo and lion that stray into the region from the Mozambique lowlands. Visitors are likely to see kudu, reedbuck, klipspringer and several other antelope; predators, including leopard and hyena, are also present. The African clawless otter is common in the upper Kairezi River, in the north-east of the park. The park is best known among wildlife conservationists for its populations of blue duiker and samango monkeys. Neither animal is found outside the Eastern Highlands. The Inyangani River Frog is an endangered amphibian found in rocky, fast-flowing streams in the montane grassland.
