Ruaha National Park is located just south of the central midpoint of Tanzania. The national park encompasses an area of 7,809 square miles (20,226 sq km) making it the largest national park in Tanzania and one of the largest in Africa.
Ruaha National Park is part of the larger Rungwa-Kizigo-Muhesi ecosystem that covers an area of 17,000 square miles (45,000 sq km). Along with Ruaha, the area includes two other game reserves and a wildlife management area. There are three primary areas for safari game-viewers to explore. The Ruaha River area is the most stunning with Mdonya woodlands and the Mbage-Mwagusi circuit.
Ngalambulwa Mountain is the tallest point in the park reaching a summit of 5,250 feet (1,600 m). Grasslands and rocky terrain surround this massif adding to the varying landscapes.
The great Ruaha River travels along the southeastern border of the park. The river name serves as the source for the national park name. This water source also serves as a draw for safari game viewing. A second river, Njombe traverses the park through gorges and rocky broken landscapes. Crocodiles can be commonly seen sunning on the banks of the rivers.
The dry seasons shrink the river, which draws wildlife in for drinking. It becomes an excellent game viewing area. The large gatherings of elephant, giraffe, buffalo, kudu, and impala can often be seen in herds around the riverbeds. The Mdonya woodlands are a great area for seeing hartebeest, sable, and roan antelope. The Mbage-Mwagusi circuit provides a good chance for seeing elephants.
