Ruaha was recently expanded to become the largest national park in Africa. It lies 130 km west of Iringa. Its name is derived from the Great Ruaha River, which flows along its entire eastern border creating spectacular gorges and scenery. Hippos, crocodiles, turtles and fish inhabit the river. The park is also known for its concentration of lesser and great kudus, its roan and sable antelopes, and its rich bird life. Photography blinds have been built at strategic places where wildlife congregates. The best months for game viewing are July to November.
