Iguazu Falls is in Argentina, but visitors can see it from either Argentina or Brazil.
Iguazu Falls tumbles over the rim of a cliff that is about 2-1/2 miles long. There are 275 individual cascades and falls, with the highest fall dropping almost 270 feet into the Iguazu River.
Iguazu Falls is part of a subtropical jungle that is rich in wildlife, including tapirs, giant anteaters, howler monkeys and jaguars.
Visitors who tour the falls from Argentina can walk around some of the falls or take a boat tour to the mouth of the waterfall. Visitors who tour the falls from Brazil can see sweeping panoramic views that give a full perspective of the falls.
The biggest waterfall at Iguazu Falls is called Garganta del Diablo or the Devil's Throat.
