The Ngorongoro Conservation Area is a UNESCO World Heritage Site located 180km west of Arusha in the Crater Highlands area of Tanzania. The main feature of the Ngorongoro Conservation Area is the Ngorongoro Crater, the world's largest inactive, intact, and unfilled volcanic caldera. The crater, which formed when a large volcano exploded and collapsed on itself two to three million years ago, is 610 metres deep and its floor covers 260 square kilometres. The park is densely populated with wildlife and is home to about 30,000 animals. Supported by a year round supply of water and food, the park supports a massive variety of animals.
There are no giraffe, topi or impala in the park - they most likely find it too difficult to negotiate the crater rim cliffs and there is also inadequate grazing for large herds of antelope, inside the park. The park is full of wildebeest, zebra, rhino, buffalo, eland, warthog, hippo and elephants. Supported by a year-round supply of water and food, the park supports a massive variety of animals, including its impressive population of predators, including lions, hyenas, jackals, cheetahs and the elusive leopard.
