Olduvai Gorge is a steep-sided ravine cutting through the Great Rift Valley on the eastern edge of the Serengeti plains, within the Ngorongoro Conservation Area in northern Tanzania. Often called the “Cradle of Mankind,” the gorge has produced some of the most important fossil discoveries in the study of human origins, the result of decades of excavation led by the Leakey family and their successors from the 1930s onward.
The site at a glance
- A roughly 48-kilometre-long gorge within the Ngorongoro Conservation Area, on the eastern edge of the Serengeti ecosystem
- Excavated by Louis and Mary Leakey from the 1930s, with major discoveries continuing through the 1950s and 1960s
- Home to the on-site Olduvai Gorge Museum, displaying fossil casts, stone tools and interpretive exhibits
- Widely referred to as the “Cradle of Mankind” for its role in the study of human evolution
Key discoveries
In 1959, Mary Leakey discovered the skull of Paranthropus boisei, a robust early hominin species dated to roughly 1.79 million years old, a find that first drew wide international attention to the gorge. The following year, in 1960, the Leakeys’ son Jonathan discovered fossils attributed to Homo habilis, a species associated with some of the earliest known stone tool use. Excavations at Olduvai have since uncovered stone tools and hominin remains spanning roughly two million years, making the gorge one of the most continuously informative sites anywhere for understanding early human and hominin evolution.
Visiting the gorge
The Olduvai Gorge Museum, perched on the gorge’s rim, presents fossil casts, stone tool displays and background on the excavation history and the species identified at the site, usually paired with a talk from a knowledgeable guide. Most visitors combine a stop here with travel between Ngorongoro Crater and the Serengeti, since the gorge sits directly along that route, adding historical depth to what is otherwise a wildlife-focused itinerary.
Things to do
- Visiting the Olduvai Gorge Museum and its fossil and stone-tool exhibits
- Learning from on-site guides about the Leakey excavations and their key discoveries
- Viewing the gorge itself from the rim, with views across the surrounding Rift Valley landscape
- Combining a stop with travel between Ngorongoro Crater and the Serengeti
Practical information
- Located directly along the main road between Ngorongoro Crater and the Serengeti, making it an easy stop for most northern Tanzania itineraries
- The museum and gorge viewpoint can typically be visited in an hour or two
- Best combined with a Ngorongoro Crater or Serengeti safari rather than visited as a standalone destination
Olduvai Gorge adds a compelling layer of human history to a northern Tanzania safari, standing at one of the most significant sites in the study of our own origins.
