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.
The Ngorongoro crater is also the world's largest inactive caldera. The crater floor covers about 260 square kilometers and is the crater is about 600 meters deep. Due to the collapse of an active volcano over 2 million years ago, the Ngorongoro crater was formed.
There are nine craters in the Conservation Area, of which Ngorongoro Crater is the biggest and most stunning. Before it collapsed, geologists estimate, its height was about 4,587m above sea level.
The stunning landscape of Ngorongoro Crater combined with its spectacular concentration of wildlife is one of the greatest natural wonders of the planet. The crater was voted one of the Seven Natural Wonders of Africa in February 2013, by the organization Seven Natural Wonders, based in the United States, which had conducted a campaign since 2008 to determine the most phenomenal natural features of Africa.
