Kakamega Forest is situated in Western Province Kenya, north-west of the capital Nairobi, and near to the border with Uganda. It is said to be Kenya's last remnant of the ancient Guineo-Congolian rainforest that once spanned the continent.
Including reserves, the forest encloses about 230 square kilometres, a little less than half of which currently remains as indigenous forest. There are numerous grassy clearings and glades. Large mammals are rare. Part of the forest also contain unique and rich highland ecosystems, but generally the fauna and flora of the Forest have not been comprehensively studied by science. The climate is very wet with over two metres of rain annually. The rainy seasons are April-to-May and August-to-September.
