About Olmoti Crater

Olmoti Crater is a volcanic crater located in the Ngorongoro highlands of northern Tanzania, within the Arusha Region. It is one of several extinct volcanic features in the highland landscape and is recognized for its steep rim and grassy interior.

The crater offers highland scenery with a rim that provides panoramic views and a crater floor that supports grassland and seasonal water bodies. Hikers and visitors in the Ngorongoro Conservation Area sometimes make short excursions to view the rim and internal features.

Geographically it sits within the Ngorongoro Conservation Area in northern Tanzania, north of the main Ngorongoro Crater and within the upland zone that transitions to the East African Rift highlands.
