Derives its name from the Ruaha River, which flows along its southeastern border. The river provides permanent water in the park and, during the dry season, animal concentration along its banks is extremely heavy.
Ruaha National Park is about two to three hours’ drive from Iringa, a famous town on the Dar - Zambia highway, and covers an area of 12, 950sq km, making it the second largest National Park in Tanzania, after Serengeti. The park is mainly woodland which provides a different habitat as compared to the popular northern Tanzania plains reserves. Ruaha National Park is famous for its elephant herds and animals that are rarely seen in the northern parks, like the greater kudu and the roan antelope. Other animals that are common include the sable antelope, lesser kudu, lions, leopard, hunting dog, buffalo, impala, waterbuck, warthog, giraffe, bushbuck, and the hippos and crocodiles which inhabit the Ruaha River. The park is also rich in bird life. The best time to visit the park is during the dry season, from May to December, when animals are concentrated along the river.
