The Ngorongoro Conservation Area is a World Heritage site which, on its western border, abuts another World Heritage site, the Serengeti National Park. The Ngorongoro crater is the world's largest inactive caldera, spanning more than 100 square miles.
Approximately 25,000 animals live in the crater, making the wildlife viewing spectacular.
