Iguaçu Falls is always ranked among the five greatest waterfalls in the world. But is it the very best? Its peak drop of 269 feet is not the largest (that honor belongs to Angel Falls in Venezuela at 3,212 feet). Nor does its average flow of 62,000 cubic feet per second compete with the 2.5 million gallons a second at Inga Falls bordering Cambodia and Laos. But “amazing” can rarely be quantified. That is definitely true at Iguaçu Falls. Based on the sheer beauty of its 275 cascades, Iguaçu Falls is often rated as the world’s best.
