Olduvai Gorge is a paleoanthropological site of major significance, where an old river has carved away the rock to expose layer upon layer of volcanic soil. This is where Dr Louis and Mary Leakey found the remains of hominids "Nutcracker Man", "Tool Making Man" and "Lucy", discoveries that have helped to fill some of the missing links in the chain of human evolution and added more evidence to the theory of modern man’s emergence in Africa.

The "Cradle of Mankind" now has a visitor centre where you may hear a short lecture on the work of the Leakey’s and their successors and a small museum where you may see some of their finds, including a giant giraffe - it is hard to believe that they were once even taller!
