The Ngorongoro Crater is the southern part of Serengeti National Park. It is the worlds greatest continuous caldera, which is non-flooded. Caused by the collapse of a volcano 3 million years ago, when the East African Rift System has developed, this crater was formed. Its  sidewalls have a height of  between 400 and 600 meters. The crater has a diameter of between 17 and 21 kilometers and its inner surface measures about 21 square kilometers.

Nearly 25.000 of large mammals are living in the crater, the number of zebras, buffalos and wildebeests is particularly high. But you often also meet  elands and gazelles. All of them are very "attractive" to lions, hyenas and leopards. Next to elephants and hippos there are still some black rhinos living in the crater, an endangered specie.
