lies on the northeastern shore of Lake Turkana in northern Kenya. Established in 1973 by the government of Kenya for the protection of wildlife and palaeontological sites there, it covers 1570 km² and is internationally known for its fossils. It was listed as a UNESCO World Heritage Site in 1997 as a part of Lake Turkana National Parks.
The park was named for Mount Sibiloi in view at Alia Bay on the south perimeter. There also is located the park headquarters of the Kenya Wildlife Service, the administering authority; camping and short-stay facilities for visitors; and the Koobi Fora Museum. Koobi Fora Spit with the facilities of the Koobi Fora research Center are to the north, but are accessible through guided tours.
The most famous remains from the park are the Australopithecus and early homo fossils. These have been removed to Nairobi, but fossil non-humanoids are on display in the museum.
Sibiloi was declared a National Park by the government of Kenya in 1973. This was undertaken primarily to ensure the long-term protection of the many important fossil sites in the area but also to conserve the rare fauna and flora endemic to area. This wildlife includes rare dry country large mammals such as Grevy zebra, gerenuk and oryx.
Sibiloi National Park and Lake Turkana lies at an approximate altitude of 375 meters (1246 feet) above sea level.
The lake shore provides important refuge to increasingly threatened crocodile and soft-shelled turtle populations, and serves as an important breeding ground for crocodiles, many different fish species and water birds. The combination of wildlife and prehistory makes Sibiloi National Park unique in East Africa and has been recognized as a World Heritage Site by UNESCO. The National Park is administered under Kenya Wildlife Service, which falls under the Ministry of the Environment and Natural Resources.
