Their name comes from the Guarani or Tupi words y (water) and ûasú [waˈsu] (big).[ Legend has it that a god planned to marry a beautiful aborigine named Naipí, who fled with her mortal lover Tarobá in a canoe. In rage, the god sliced the river creating the waterfalls, condemning the lovers to an eternal fall. The first European to find the falls was the Spanish Conquistador Álvar Núñez Cabeza de Vaca in 1541, after whom one of the falls in the Argentine side is named.[1] The falls were rediscovered by Boselli at the end of the nineteenth century, and one of the Argentine falls is named after him. Iguazu Falls was short-listed as a candidate to be one of the New7Wonders of Nature by the New Seven Wonders of the World Foundation. Some of the individual falls are up to 82 meters (269 ft) in height, though the majority are about 64 metres (210 ft). The Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese), a U-shaped, 82-meter-high, 150-meter-wide and 700-meter-long (490 by 2300 feet) cataract, is the most impressive of all, and marks the border between Argentina and Brazil. Two thirds of the falls are within Argentine territory. About 900 meters of the 2.7-kilometer length does not have water flowing over it. The water of the lower Iguazu collects in a canyon that drains in the Paraná River at Argentina, shortly downstream from the Itaipu dam.The falls can be reached from the two main towns on either side of the falls: Foz do Iguaçu in the Brazilian sarantonello Puerto Iguazú in the Argentina province of Misiones as well as from Ciudad del Este (Paraguay) on the other side of the Parana river from Foz do Iguaçu. The falls are shared by the Iguazú National Park (Argentina) and Iguaçu National Park (Brazil). The Argentine access is facilitated by the Rainforest Ecological Train, which brings visitors to different walkways.
