Ruaha National Park is the largest national park in Tanzania. It covers an area of about 22,000 km². It is located in the middle of Tanzania about 130 km from Iringa. The park is part of a more extensive ecosystem which includes Rungwa Game Reserve, Usangu Game Reserve, and several other protected areas.
The name of the park is derived from the Great Ruaha River, which flows along its south-eastern margin and is the focus for game-viewing. The park can be reached by car via Iringa and there is an airstrip at Msembe, park headquarters.
The creation of a national park in this area was first proposed in 1949 by the Senior Game Ranger in Mbeya, George Rushby. In 1951 it was gazetted by the British colonial authorities as an extension of the neighbouring Rungwa Game Reserve. People living in the new protected area were subsequently forced to move out. In 1964 it was excised from the game reserve and elevated to full park status. In 2008 it was extended to incorporate the former Usangu Wildlife Management Area, in the upper Ruaha catchment, making Ruaha the largest National Park in Africa.
Ruaha is famous for its large population of Elephants. Presently about 10.000 are roaming the park. Ruaha National Park is also a true birdwatchers paradise: 436 species have been identified of an estimated total of 475. Among the resident birds are different species of Hornbills, Kingfishers and Sunbirds. Also many migrants visit Ruaha, e.g. the White Stork
Other special animals in Ruaha are: the African Wild Dog and Sable Antelope. Rhinoceros were last been sighted in 1982 and are probably extinct in the park due to poaching.
The best times to visit for predators and large mammals is the dry season (May–December) and for birds and flowers, the wet season (January–April).
