Located within the Ngorongoro Conservation Area is the Olduvai Gorge, 180 km from Arusha. It was here that Dr. Louis Leakey discovered the remains of Homo hablis or “Handy man” regarded as mankind’s first step on the ladder of human evolution. But many more fossils have been discovered here including those of prehistoric elephants, giant horned sheet and enormous ostriches.
