A vast collapsed volcano whose grassy floor holds lions, black rhinos and some 25,000 large animals
Ngorongoro is a natural amphitheatre. The NCAA describes it as the world's largest intact, unfilled volcanic caldera, formed when a volcano that may once have rivalled Kilimanjaro collapsed in on itself around two and a half million years ago. Today steep forested walls about 600 metres high enclose a floor of open grassland, swamps, a soda lake and patches of woodland, and the descent from the misty rim to the sunlit plain below is one of the great moments of any Tanzanian safari.
Around 25,000 large animals live in the crater, most of them grazers such as wildebeest, zebra, buffalo and gazelles. UNESCO notes that the crater has one of the highest densities of mammalian predators in Africa, chiefly lions and spotted hyenas, and flamingos often gather on the shallow soda waters of Lake Magadi. The crater is also one of the most reliable places in East Africa to see the endangered black rhino, which has recovered slowly since its numbers collapsed in the 1980s and early 1990s.
The NCAA traces the name to a Maasai phrase meaning big bowl, which was misspelt in early records. Pastoralists have used the highlands for centuries: the Datooga arrived around 1700 and were displaced by the Maasai in the 1800s. The Austrian explorer Oscar Baumann is the first European known to have entered the crater, in 1892, and in the German colonial period the Siedentopf brothers farmed on the crater floor until the First World War.
The Ngorongoro Conservation Area was created in 1959 when it was separated from the Serengeti, with a pioneering multiple land-use model intended to protect wildlife while allowing Maasai herders to remain. UNESCO inscribed the area as a natural World Heritage Site in 1979 and added cultural criteria in 2010 for its fossil and archaeological sites, including Olduvai Gorge and the Laetoli footprints. Grazing livestock inside the crater itself has been restricted since 2015, and since 2022 a government programme to move residents out of the conservation area to Msomera and other sites has been criticised by human rights groups, while the government says it protects the ecosystem.
Maasai communities have lived in the wider conservation area for generations, grazing cattle, sheep and goats on the highlands around the crater, and their red cloths are a common sight along the rim road. The NCAA runs designated cultural bomas where visitors can learn about Maasai homes, dress and herding life; outside these, photographing local people is prohibited. The future of residents in the conservation area is a sensitive and contested issue, so it is worth asking your guide about it with respect rather than assuming.
A visit usually means a half or full day on the crater floor with a licensed guide in a 4x4, descending in the morning and climbing out before the gates close in the late afternoon. Game drives circle the soda lake, the Munge stream, the swamps and the Lerai Forest, and there are designated picnic sites where visitors may leave the vehicle. Walking is not allowed on the floor, but guided walks with an armed NCAA ranger can be arranged on the rim and in other parts of the conservation area.
Lodges and campsites line the rim, which sits high enough to be cool and often misty, so mornings start chilly even when the crater floor is warm. Because the crater is enclosed, sightings are concentrated and vehicles can gather at a kill, so the NCAA limits numbers at sightings and asks drivers to keep their distance and their voices down.
The NCAA notes that the crater can be visited all year thanks to good roads and resident wildlife. The dry season from June to October gives the easiest driving and shorter grass, and January and February are also generally dry, with migrating herds on the nearby Ndutu plains. During the long rains, roughly March to May, the floor is green and visitor numbers fall. The rim is cold at night and early in the morning at any time of year.

The crater lies on the main road between Arusha and the Serengeti, about an hour's drive beyond the farming town of Karatu, where there are many lodges. Elsewhere in the conservation area are the smaller Olmoti and Empakaai craters, the Ndutu plains on the Serengeti border, Olduvai Gorge and its museum, the Shifting Sands and the Laetoli footprint site. Lake Manyara National Park and the town of Mto wa Mbu lie at the foot of the Rift Valley escarpment to the east.
