Four times wider than Niagara Falls in the United States, and undoubtedly the most spectacular in South America, the Iguaçu Falls in Paraná is where the powerful river Iguaçu hurtles into a deep canyon, carved in the shape of a horseshoe in the gigantic basalt flow which, during the Triassic period, spread out from north-eastern Uruguay to the region. The thunder of the water and the brilliance of the rainbow crowning the fury of the torrent stay in the mind as a rare and unforgettable testimony to the grandeur of the Earth.

Iguaçu Falls was first seen by European people in 1541, when the expedition of Dom Alvar Nunez Cabeza de Vaca found it.

Today, the region is the border among three countries: Brazil, Argentina and Paraguay, and can be reached by plane or through the Asunción-Paranaguá highway.

Iguaçu Falls, in the Iguaçu River, is, actually, a system of 275 falls along almost five kilometers in the Brazil-Argentina border. The highest fall is 64 meters high and the others has 30 to 40 meters high. Both, Brazil and Argentina, surrounds the area with national parks, where several species of animals and plants can be found.

The region is full of tourist attractions: Iguaçu Falls and national parks in Brazil and Argentina; Itaipu, the world's largest hydroelectric; Macuco Safari, with rafting near the falls and ecological trails;  Foz Tropicana Bird Park and many others.
