The Ngorongoro Conservation Area is home to the world’s largest cauldron formed by a violent volcano eruption millions of years ago. The Ngorongoro Crater is commonly referred to as the 8th wonder of the world. Best known for its dense population of wild animals all contained in the small area of the crater’s floor, the Ngorongoro Crater is one of the best spots in Tanzania for sightings of the elusive rhino. The crater has an incredibly diverse eco-system to match its varied animal population. This 10-mile wide volcano top with 2,000 feet high walls is one of the most spectacular places imaginable. Watching a sunset over the rim of the crater is breathtaking.
