Venezuela's Angel Falls is the tallest in the world at 3,211 feet high.
Unlike most cascades, Angel Falls isn't fed by snowmelt, a lake, or a river—but by rainfall from the tropical clouds.
Angel Falls is located in Canaima National Park, which has an on-site airport that connects visitors to and from Venezuela's capital city, Caracas.
