Iguazu Falls are waterfalls generated by the Iguazú River on the border between the Argentine province and the Brazilian state. They are the largest waterfalls in the world with a width of 7.65 km. The system consists of 275 waterfalls, with heights of up to 70 meters, along 4 kilometers of the Iguazú River. The Garganta del Diablo (“Devil’s Throat”) (Argentine side), a U-shaped gorge 150 meters deep and 700 meters long, is the most imposing, and marks the border between Argentina and Brazil. The majority of the falls are in Argentine territory, but from the Brazilian side (600 meters) you get a more panoramic view of the Garganta del Diablo.
The falls are shared by the Iguazu National Park (Argentina) and the Iguaçu National Park (Brazil). These parks were designated a World Heritage Site by UNESCO in 1984 and 1986 respectively.
