A supervolcano fell.
A world was born inside.
Two and a half million years ago, a volcano the size of Kilimanjaro collapsed inward. What remained is the Ngorongoro Crater — the world's largest intact volcanic caldera and one of the most extraordinary concentrations of wildlife on Earth.
The crater walls rise 600 metres above the floor, preventing most animals from leaving. Lion prides have held the same territories for generations. Black rhinoceros find one of their last viable East African refuges here. Elephant bulls with tusks that sweep the ground. All Big Five in 260 square kilometres.
Ally has guided here for over 20 years. He knows which pride rests under which fig tree in the morning, where the black rhino wallows before noon, and which rim viewpoint catches the first light in a way most visitors never find.
