In the northeast corner of Argentina, 275 distinct waterfalls slice the mighty Iguazú River into its upper and lower courses. In the Guaraní native language, Iguazú means “big river,” and is it ever! Upon viewing the immense falls at Iguazú, former U.S. First Lady Eleanor Roosevelt exclaimed “Poor Niagra!” The waterfalls stretch 82m high (270ft), and within Iguazú National park it is possible to see the intersection of three nations – Brazil, Argentina, and Paraguay – from a single lookout over the river.  A series of meandering catwalks leads visitors on a safari through tropical forests, ending at the very mouth of the famed Devil’s Throat section of the falls.
