The steep-sided ravine where the Leakeys uncovered nearly two million years of human ancestry, with an on-site museum
Olduvai Gorge, also spelled Oldupai, cuts through the eastern edge of the Serengeti plains on the road between the Ngorongoro Crater and the Serengeti. At first sight it is a dry, scrubby ravine, but its walls expose a sequence of ancient lake beds, river sands and volcanic ash spanning close to two million years, and in those layers scientists have found fossils of several early human species alongside the simple stone tools they made.
For visitors the gorge is a short, rewarding stop on the way to or from the Serengeti. A museum on the rim, overlooking the striking rock formation in the middle of the gorge, displays fossils, casts and stone tools, and guides give talks on the site before taking groups down towards the excavation areas. Seeing the actual landscape where these discoveries were made gives a real sense of how deep human history runs in this part of Africa.
The name comes from the Maasai word oldupai, for a wild sisal plant that grows in the area; Wilhelm Kattwinkel, a German visitor, recorded it as Oldoway after visiting in 1911. Hans Reck led an expedition in 1913, and Louis Leakey began work in 1931, later joined by Mary Leakey. The gorge's deposits are divided into numbered beds, the oldest of which date back roughly 1.7 to 1.9 million years and contain the simple chopping tools known as the Oldowan industry.
In July 1959 Mary Leakey found a robust skull that Louis named Zinjanthropus, now classified as Paranthropus boisei and nicknamed Nutcracker Man. The following year the team found the remains that became the type specimen of Homo habilis, a species linked to early tool making, and later work recorded Homo erectus as well. The Leakeys and their colleagues worked here for decades, and UNESCO cites Olduvai, together with the Laetoli footprints, as a key reason for adding cultural criteria to the Ngorongoro Conservation Area World Heritage listing in 2010. A new museum opened in 2017 beside the older one founded in the Leakey era.
The land around the gorge is home to Maasai herders, and their cattle, goats and bomas are often seen on the dry plains along the road. Local people work at the museum and as guides, and Maasai craft sellers often set up near the entrance. Remember that NCAA rules allow photography of people only in designated cultural bomas, so always ask before taking pictures and respect a refusal.
A typical visit takes one to two hours. Groups start at the museum, where a short talk explains the geology of the beds and the key discoveries before visitors move through the exhibition halls. With an official guide it is possible to go down into the gorge to see the excavation areas. The museum complex has a shop selling books and local products, a restaurant and toilets, which makes it a natural break on the long drive to the Serengeti.
The nearby Shifting Sands, a crescent-shaped dune of black volcanic ash that slowly moves across the plain, can be combined with the gorge and is covered by the same NCAA site fee. Bring sun protection and water, as the gorge is hot and exposed at midday.
The gorge can be visited all year, and the NCAA notes that an official guide is needed to visit the excavations. The dry months from June to October are dusty but make the road conditions easiest. From December to March the surrounding plains can be busy with migrating wildebeest and their calves, which makes the drive here especially rewarding. Midday is hot; mornings and late afternoons are more comfortable for walking down into the gorge.

Olduvai lies in the western part of the Ngorongoro Conservation Area, on the road between the Ngorongoro Crater rim and Naabi Hill Gate at the edge of the Serengeti. The Shifting Sands dune is a short drive to the north, the Ndutu plains lie to the south-west, and the Laetoli footprint site is further south. The crater rim lodges and Karatu are the nearest places with a wide choice of accommodation.
