The Iguazu Falls, Argentina-Brazil, 2008
On the border of two countries of South America, Brazil and Argentina, there is a complex of the Iguazu Falls which is one of the most spectacular nature miracles. 270 individual cascades, milling about 40 million cubic meters of water per hour or 1 billion tons in twenty-four hours, spread on 2.7 km width. It's no wonder that the word "iguazu" means "great waters' in language of local Indian tribe Guarani.
Though the Iguazu isn't relatively high, it throws down water from the altitude of 82m, and it is one of the powerful waterfalls in the world. The most detailed definition of the Iguazu Falls was given by Eleanor Roosevelt, the wife of the American President Franklin Roosevelt: "Poor Niagara! This makes Niagara look like a kitchen faucet".
Tour operators usually differ in the opinion: which of the Falls' parts is the most interesting one; but as a tourist who has visited both places many times, I can say that it's worth to visit both Argentinean and Brazil parts of the Iguazu. They are really very different and each of them is nice in its own way.
