What is Ngorongoro Crater?

Ngorongoro Crater is the world's largest intact volcanic caldera and one of Africa's most extraordinary wildlife destinations. Formed approximately two to three million years ago when a massive volcano collapsed inward after a major eruption, the crater now covers about 260 square kilometers and supports one of the densest concentrations of wildlife in Africa. The crater floor contains grasslands, swamps, forests, rivers, and lakes that sustain thousands of animals year-round.
