No other National Park in Tanzania has the diversity of Ruaha. Elephant in huge numbers are a common site and the population seems to be growing. Giraffe are everywhere, as are zebra and impala among the other herbivores. Both the greater and lesser kudu occur here, as do the magnificent eland, sable and roan antelope. The Ruaha River also provides an ecosystem on its own with its huge Nile crocodiles, pods of hippo and all the other smaller mammals and reptiles.
Ruaha has an abundance of predators, and a particularly healthy lion population - it's not uncommon to see a pride with twenty or more. We are treated to regular sightings of large males with magnificent manes. The rugged terrain of Ruaha is perfect for leopard and they are seen regularly. The African hunting dog also occurs in the Park although their huge ranges make them a little more difficult to find. The same is the case with cheetah. Hyena and jackals are a common camp visitors and their cries are often heard after dark.
