Without a doubt, Puerto Iguazú entered the world tourist map thanks to its magnificent waterfalls. Recognized in 1984 as a World Heritage Site by UNESCO, The Iguazú Falls can be seen from the Argentina site as well as from the Brazilian site. Puerto Iguazu is sure to be smaller and quieter (but no further from the falls) than Foz do Iguaçu, its Brazilian counterpart. Essentially a tourist town, it's focused on servicing the hundreds of thousands who come to wonder at the falls and national park. The tremendous amount of water (an average of 553 cubic feet per second) thundering down 269 feet, the tropical location and the sheer beauty that 'led Eleanor Roosevelt to say "Poor Niagara". Taller than Niagara Falls, twice as wide with 275 cascades spread in a horseshoe shape over nearly two miles of the Iguaçu River, Iguaçu Falls are the result of a volcanic eruption which left a large crack in the earth. A visit is a jaw-dropping, visceral experience, and the power and noise of the cascades live forever in the memory. Along with Nahuel Huapi National Park in Patagonia, Iguazu Falls is one of the most frequented tourist sites in Argentina, and for good reason. Visitors can enjoy the awe inspiring views of the falls along with tours, treks, and water sports at their base.
