Olduvai Gorge is one of the most important prehistoric sites in the world. The site was occupied by Homo habilis approximately 1.9 million years ago, Paranthropus boisei 1.8 million years ago, Homo erectus 1.2 million years ago and Homo sapiens 17,000 years ago. The extraordinary presence of pre-man species has given Tanzania the nickname as the cradle of man.
This site is also significant in showing increased development and social complexities in hominins. In the 1930’s Louis and Mary Leakey found some of the oldest evidence of the production and use of stone tools, which indicates the increase in cognitive capacities of our ancient predecessors. The collection of tools and animal remains in a central area suggest increased social interactions and communal activity.
Located on the Western side of Ngorongoro Conservation Area, Olduvai Gorge is ideally located near the main road that connects the Serengeti and Ngorongoro to Arusha. The Gorge can be reached by car from Arusha.
