While traveling in Tanzania with G Adventures, I visited Ngorongoro Crater. It is the world’s largest inactive, intact and unfilled volcanic caldera.
The crater, which formed when a large volcano exploded and collapsed in on itself, is 2,000 feet deep and covers 100 square miles.
Here are black rhino, hippos and a great flock of flamingos that stretch across the horizon plus lions, zebras, hyenas, elephants and other birds and animals.
