It is an unspoiled wilderness of 870 sq km and unprecedented beauty. Game tracking can be challenging but very rewarding here and game viewing includes lion, elephant, cheetah, leopard black rhino, zebra, gazelle, oryx and some of the rarer antelope, Lesser Kudu and duiker, also the more common Dik Dik, one of Africa's smallest antelope. Large prides of lion can be seen and some of Kenya's largest herds of buffalo. The rivers abound with hippo and crocodile, fishing for barbus and catfish is permitted at camp sites and along the Tana River.

Birdlife is abundant and over 300 species of birds have been recorded.

The Park is renowned for the world famous lioness "Elsa". And so the setting for Joy Adamson's book Born Free which illustrates the story of the Adamson's life and research amongst lion and cheetah.

Best time to go is from May to December.
