Iguazu Falls

Iguazu Falls is a system of waterfalls on the Iguazu River along the border between Argentina's Misiones Province and Brazil's Parana State, and is considered the largest waterfall system in the world, made up of about 275 individual drops spread across a combined width of some 2,700 meters. Its longest single drop reaches 82 meters, and the falls carry an average flow of about 1,756 cubic meters per second; most of the individual falls lie on the Argentine side of the river, even though the Iguazu itself flows mainly through Brazil before reaching the border. Spanish conquistador Alvar Nunez Cabeza de Vaca was the first European to document the falls, in 1541, and UNESCO designated the site a World Heritage Site in 2013.
