Is a not much visited national park, although one of the largest wilderness areas in Tanzania. It has a reputation of being remote, but actually it is only 115 km from Iringa on an all-weather road.

The Great Ruaha River runs through the park. It has been considered a permanent watercourse but in recent years it has actually dried up during the dry season, with crocodiles and hippos surviving in pools with standing water. Animals also include a big number of elephants as well as greater and lesser kudu, zebra, bushbuck, giraffe, roan antelope, sable antelope, buffalo, eland and several others. Various kinds of woodland and bushland dominate the vegetation. Many visitors consider it the best of all parks in Tanzania.
