Located 100km from Nairobi and lying on 766 square km, the park contains a wide range of landscapes from their deep, v-shaped valleys intersected by streams, rivers, and waterfalls. Moorland, bamboo forests and rainforests are found at lower altitudes.
Animals mainly observed are the leopard, elephant, East African wild dog, giant forest hog, bushbuck, mountain reedbuck, waterbuck, cape buffalo, suni, side-striped jackal, eland, duiker, olive baboon, black and white colobus monkey, and sydes monkey. Rarer sightings include those of the African golden cat and the bongo-an elusive forest antelope that lives in the bamboo forest.
The Aberdare National Park also contains a large eastern black rhinoceros population.
Bird watching is incredible here with over 250 species of birds in the park including the Jackson's francolin, sunbirds and plovers. Birds of prey are of particular interest with African goshawks, Ayres’ hawk eagles, rufour-breasted sparrow hawk and mountain buzzards.
The rainforest is a vital water catchment area with attractive streams and rivers supporting a broad range of wildlife.
