The Ngorongoro Crater is the world’s largest unbroken and unflooded volcanic caldera. The crater was formed after a Volcano exploded 2-3 million years ago. The original volcano was almost as high as Mt Kilimanjaro, but the remaining wall is around 500-600 metres.
Inside the crater is a population of around 25,000 animals including lions, elephants, black rhino, hippopotamus, wildebeest, gazelles and zebra.
