The Iguazu Falls
The Iguazu Falls (Spanish: cataratas del Iguazú), or Iguaçu Falls (Portuguese: cataratas do Iguaçu), or Iguassu Falls, located in the middle of the rain forest on the border between Argentina (80%) and Brazil (20%), are a natural wonder world heritage by UNESCO in 1984. the first European to contemplate is Álvar Núñez Cabeza de Vaca in the sixteenth century. On both sides of the falls, the Brazilian and Argentine governments have created national parks, the National Park of Iguaçu in Brazil and Iguazú National Park in Argentina.

It's called the Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese ( "Devil's throat"). All the waterfalls pours up to six million liters of water per second.
These falls interrupt the course of the Iguaçu River, a tributary of the Paraná, between the Brazilian state of Paraná and the Argentine province of Misiones. They are among the most impressive in the world, in a geography favoring the creation. The waterfall Seven Falls neighbor was probably also phenomenal but disappeared in 1982 after the impoundment of the reservoir Itaipu dam.
On each side of the border, the falls are part of a natural reserve: the Iguazú National Park (Argentina) and Iguaçu National Park (Brazil). These parks were inscribed on the World Heritage List by UNESCO in 1984 and 1986, respectively.The majority of falls are on the Argentinian territory. In Argentina, several circuits of visits have been built in the middle of the forest and above the various branches of the river, via different gateways. It is possible to approach a few meters of the falls. A train leads to different tours starting points, the most impressive waterfall, the Garganta del Diablo (U-shape, 700 m long, 150 m wide and 82 m high).
