Adjacent to the Meru National Park, on the south of the Tana River, is the Kora National Park, created largely through the efforts of George Adamson, whose remarkable work in rehabilitating tame lions has made him a legend in Kenya. George Adamson died in 1989.

The Kora National Park was gazetted in 1973 as a reserve and later in 1990 as a park. It comprises of an area of slightly over 1,787 Sq. Kms. This triangle of dense woodland and scrub is limited along its 65 km northern boundary by the Tana River, which rises in the highlands between the Aberdares and Mount Kenya, before commencing its 700 km passage to the Indian Ocean.

The western boundary follows a straight line from Tana River which forms a joint boundary with the adjacent Kitui Reserve, while the eastern boundary runs along Mwitamyisi River. The land surface slopes gently from an altitude of 490m in the southwest and about 270m in the northeast.

Central areas comprise of an undulating peneplain through which basement ridges protrude above the surface as rocky inselbergs the highest of which are Mansumbi, 488 m, Kumbulanwa, 450m and Kora Rock, 442m. The park also has several seasonal rivers.

Kora has a unique and diverse fauna. Twenty one species of fish have been caught along the Kora stretch of Tana River. Almost 500 species of insects, 33 species of molluscs, 40 species of reptiles, 5 species of amphibians, 215 species of birds and 51 species of mammals including elephant, Lesser Kudu, wild dog, striped and spotted hyenas, lion, leopard and cheetah. There are tracks negotiable by ordinary cars. Camping is permitted at the park.
