Gambella National Park is in the Gambela Region of Western Ethiopia. Wildlife populations in Gambella are among the highest in all of Ethiopia. Gambella is only accessible via charter aircraft on an organized safari using tented camps and private aircraft.
The Gambella (or Gambela) National Park is located about 850 km due west of Ethiopia's capital, Addis Ababa. It is one of the largest parks on the country.
It was established in 1974 to protect two antelope species which at the time were at the risk of extinction in the region.
It is 4,575 km² (1,766 sq mi) in size.
Gambella National Park has one of the highest concentrations of wildlife in Ethiopia. Sixty-nine mammal species are found in the protected area, including African elephant, African buffalo, bushpig, common warthog, Nubian giraffe, hippopotamus, Nile lechwe, tiang, waterbuck, cheetah, leopard, lion, mantled guereza, olive baboon, patas monkey and spotted hyena.
