Udzungwa is one of Tanzania's largest park's but accessibility is severely limited-game drives are not possible, and therefore only trekking expeditions can be organized into the wilderness.

 

The park hosts six species of primate, two of them are of endemic forms - the Red Colobus Monkey and the Sanje Crested Mangabey, discovered in 1979. The large resident populations of Elephant, Buffalo, Lion, Leopard, Wild Dog and Sable Antelope reside primarily on the side of the mountain range which is presently inaccessible. Other attractions of this park include the spectacular mountain scenery with rain forest, wooded grasslands, rock faces, rivers and waterfalls; the falls on the Sanje River which drops some 170 m through the forest and into the valley below; and the mountain plateau with views of over 100 km, much of it across a mosaic of mountain forest and grassland
