The largest intact caldera in the world, the Ngorongoro Crater shelters one of the most beautiful wildlife havens anywhere. A permanent population of more than 30 000 animals inhabits a mere 260 km? (100 square miles) in the 600 m (2 000 ft) deep Crater, making this one of the few places in Africa where guests stand a great chance of seeing the entire Big Five in the course of a single game drive. The Maasai follow tradition by grazing their cattle on the Crater floor and it is not unusual to see these domestic animals and buffalo foraging together, with a lion gazing fixedly mere metres away.
