About the Reserve
The Ngorongoro Crater is the largest intact and unflooded volcanic caldera in the world, formed roughly three million years ago when a colossal volcano collapsed inward. Its 260 square kilometre floor hosts a permanently resident population of approximately 30,000 large mammals including the densest concentration of lion in Africa, the critically endangered black rhinoceros, and vast herds of wildebeest, zebra, and gazelle. The surrounding highlands of the Conservation Area are inhabited by Maasai pastoralists who share the land with wildlife under a unique co-existence arrangement.
