Ngorongoro Crater is the World’s Biggest Intact Volcanic Caldera
Ngorongoro Crater is approximately 16 to 19 kilometers in diameter, and the height of its walls range between 400 and 610 meters. There are a few calderas around the world, but the Ngorongoro Crater is unique because it’s the biggest one with fully intact/unbroken walls and hasn’t filled up with water.
