Tanzania’s UNESCO World Heritage listed Ngorongoro Conservation Area includes the spectacular Ngorongoro Crater, the world’s largest caldera. Preservation and protection of the region is globally critical given the biodiversity, presence of threatened species, and the density of wildlife inhabiting the area; and it is central to the annual migration of wildebeest, zebra, gazelles and other animals into the northern plains.
Ngorongoro Crater, created two-three million years ago when a large volcano exploded and collapsed on itself, is around 600m deep and 16-19km in diameter. The enclosed nature of the crater has meant it has formed its own ecosystem. It is often referred to as ‘Africa’s Eden’.
Also in the conservation area is Olduvai Gorge, a 14km long deep ravine. Early hominid footprints dating back 3.6 million years were unearthed here, so the area archaeological and evolutionary significance.
