The Ngorongoro crater, often called 'Afica's Eden' is situated at the foot of Mount Kilimanjaro, is the world's largest unbroken, unflooded volcanic caldera.
The Crater, which formed when a giant volcano exploded and collapsed on itself some two to three million years ago, is 610m deep and its floor covers 260 km.

The Crater floor is a natural sanctuary for thousands of animals and many species of insects and birds. Lush highlands surround the Crater, falling away to the tawny plains and alkaline lakes of the Great Rift Valley.
Just outside the crater’s ridge, tall Masaai herd their cattle and goats over green pastures through the highland slopes, living alongside the wildlife as they have for centuries.
