In the morning you will descend to the crater floor, where you will hope to see some, if not all, of the Big Five. Ngorongoro Crater is indisputably one of Africa's most beautiful nature reserves and is certainly one of the most spectacular settings found anywhere. It is the largest intact crater in the world and was declared a World Heritage Site in 1978. Geologically, Ngorongoro is the remnant of a volcano that blew apart, leaving a flat plain area ringed with steep walls. The Ngorongoro volcano, before it exploded and collapsed two million years ago, was one of the world's tallest mountains. Unlike the Serengeti and Masai Mara, the migration in the Ngorongoro Crater is scant, as it has an abundant year-round food and water supply, and the walls of the collapsed volcano discourage migration. Animals within the Ngorongoro Crater are less shy of people and safari vehicles, so it's easier to view the animals up close. Views from the rim of the crater are sensational. On the crater floor, grassland blends into swamps, lakes, rivers, woodland and hills. The Masai are permitted to water their cattle at the permanent lake and can be seen leading their animals in and out of the crater. The most commonly seen animals are lion, wildebeest, zebra, eland, bushbuck, cheetah, jackal, buffalo, Grant's gazelle, Thompson's gazelle and black rhinoceros.The afternoon will be at your leisure, you may choose to partake in walking activities, or a coffee tour.
