Ruaha National Park takes 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 spectacular. Ruaha National Park is about two to three-hour drive from Iringa, a famous town on the Dar es Salaam to Zambia highway. Covering an area of 20,226 square kilometers, Ruaha is the largest National Park in Tanzania. Its borders were extended in 2008 to include Usangu Game Reserve to protect the Ihefu wetlands and the Great Ruaha River catchment areas and biodiversity.
Ruaha is believed to have a higher concentration of elephants than any National Park in East Africa. It is also a place where, magnificent mammals like Kudu, Sable and Roan antelopes can easily be spotted in the Miombo woodland. The park is also a habitat for the endangered wild dogs. Other animals in the park include lions, leopards, cheetah, giraffes, zebras, elands, impala, bat eared foxes and Jackals.
