One of Brazil's top tourist attractions, Foz de Iguacu's famed Falls' flow capacity is three times as much as Niagara Falls. Situated in Iguazu National Park, home to an amazing numbers of birds, the falls marks the border between Brazil and Argentina. Take a helicopter flight over the falls or a trike flight over the lake and see Igaipu Dam, on the Parana River, the dividing line between Brazil and Paraguay, as well as getting views of a Buddhist temple and the international bridge.
