Go rafting beneath Iguaçu Falls, set amid rain forest teeming with butterflies, birds and many other animals. These majestic waterfalls in southern Brazil are one of the great wonders of the Americas, with 275 individual falls encompassing a vast area protected by two national parks. The highest fall, the Garganta do Diabo (Devil's Throat) reaches 70m (230ft), which is one and a half times the height of Niagara Falls. The Iguaçu Falls span the border with Argentina; access to the Garganta do Diabo is from the Brazilian side, but over the border there are walkways which come closer to many of the other falls.
