Published on 08/15/2026 at 14:54 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Ngorongoro Crater is a volcanic caldera in northern Tanzania, within the Ngorongoro Conservation Area. Its floor lies in a basin ringed by a high rim, and the whole form is immediately legible from above.
Ngorongoro Crater’s volcanic basin and high rim
The crater measures about 16 to 19 km across and covers 264 sq km, with walls rising about 610 m above the floor.16 to 19 km across The basin sits in the Eastern Great Rift Valley, where volcanic landforms and highland edges shape the wider setting.Eastern Great Rift Valley
Ngorongoro is thought to have formed about 2.5 million years ago, when a large volcano collapsed inward after a major eruption.about 2.5 million years ago The result is an enclosed geological bowl with broad grassland on the floor and a steep enclosing edge.
Ngorongoro Conservation Area and Maasai presence
The crater sits inside the Ngorongoro Conservation Area, established in 1959 as a multiple land-use area.established in 1959 Wildlife and semi-nomadic Maasai pastoralists share the wider landscape, which gives the place a cultural frame as well as a geological one.
The conservation area includes highland plains, savanna, woodlands and forests, so the crater belongs to a wider landscape rather than standing alone as a hollow in the ground.highland plains and forests The World Heritage designation, granted in 1979, covers this broader setting and its long record of human occupation and environmental change.World Heritage designation
Ngorongoro Crater in the landscape of northern Tanzania
The crater lies west of Arusha in northern Tanzania, within the country’s Great Rift Valley country of highlands and volcanic forms.west of Arusha The basin’s scale, height and enclosing rim make it one of the clearest geological forms in East Africa.
Inside the rim, open grassland, scattered trees and a shallow lake define the floor. The crater’s form is simple enough to read at a glance, yet large enough to hold a dense and layered landscape.
Visiting Ngorongoro Crater: what travellers from Western Europe should know
