Ngorongoro Crater

Tanzania's Ngorongoro Crater is one of Africa's geological and biological treasures. This large, unbroken, unflooded volcanic caldera has provided a natural enclosure for a wide variety of wildlife, making it an ideal location for conservation efforts. Unfortunately the enclosure also leaves wildlife with no escape from the barrage of tourists who flock here to enjoy the crater's mystique and beauty.
