Ngorongoro Crater is indisputably one of the natural wonders of the
world. Two million years ago, a volcano collapsed on this site and
formed a perfect caldera, an unbroken natural bowl with a diameter
of 12 kilometres. The crater is like a giant natural zoo, with a
dense concentration of wildlife including lions, leopards,
elephants, baboons and rhinos.Ngorongoro is also home to members of
the Maasai tribe who continue to pursue a traditional way of life in
and around the Crater, which has symbolic and historical
significance in Maasai culture.
