Iguazu Falls

Iguazu Falls, Iguassu Falls, or Iguaçu Falls (Portuguese: Cataratas do Iguaçu [kataˈɾatɐz du iɡwaˈsu]; Spanish: Cataratas del Iguazú [kataˈɾataz ðel iɣwaˈsu]; Guarani: Chororo Yguasu [ɕoɾoɾo ɨɣʷasu]) are waterfalls of the Iguazu River located on the border of the Brazilian State of Paraná and the Argentine Province of Misiones. The falls divide the river into the upper and lower Iguazu. The Iguazu River originates near the city of Curitiba. It flows through Brazil for most of its course. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Brazil and Argentina.

The name "Iguazu" comes from the Guarani or Tupi words y [ɨ], meaning "water", and ûasú [waˈsu], meaning "big". Legend has it that a god planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In rage the god sliced the river, creating the waterfalls and 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.

Geography

Iguazu Falls is located where the Iguazu River tumbles over the edge of the Paraná Plateau, 23 kilometres (14 mi) upriver from the Iguazu's confluence with the Paraná River. Numerous islands along the 2.7-kilometre (1.7 mi) long edge divide the falls into about 275 separate waterfalls and cataracts, varying between 60 metres (200 ft) and 82 metres (269 ft) high. About half of the river's flow falls into a long and narrow chasm called the Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese). The Devil's Throat is U-shaped, 82-meter-high, 150-meter-wide, and 700-meter-long. The border between Brazil and Argentina runs through the Devil's Throat.[contradiction]

About 900 meters of the 2.7-kilometer length does not have water flowing over it. The edge of the basalt cap recedes by 3 mm (0.1 in) per year. The water of the lower Iguazu collects in a canyon that drains in the Paraná River, a short distance downstream from the Itaipu Dam. The junction of the water flows marks the border between Brazil, Argentina, and Paraguay. There are points in the cities of Foz do Iguaçu, Brazil, Puerto Iguazú, Argentina, and Ciudad del Este, Paraguay, which have access to the Iguazu River where the borders of all three countries can be seen, a popular tourist attraction for visitors to the three cities.

Tourism

There are two international airports close to Iguassu Falls: the Brazilian Foz do Iguaçu International Airport (IGU) and the Argentine Cataratas del Iguazú International Airport (IGR). Argentina's airport is several kilometers from the Iguassu Falls and from the neighboring city Puerto Iguazu. Brazil's airport is on Foz do Iguaçu, Brazil. LAN Airlines and Aerolíneas Argentinas have direct flights from Buenos Aires and several Brazilian airlines as TAM Airlines, GOL, Azul, WebJet offer service from the main Brazilian cities to Foz do Iguaçu.

Access

The falls can be reached from the two main towns on either side of the falls: Foz do Iguaçu in the Brazilian and Puerto Iguazú in the Argentine province of Misiones, as well as from Ciudad del Este, Paraguay on the other side of the Paraná river from Foz do Iguaçu. The falls are shared by the Iguazú National Park (Argentina) and Iguaçu National Park (Brazil). The two parks were designated UNESCO World Heritage Sites in 1984 and 1987, respectively.

The Brazilian Iguaçu National Park is spectacular as well as pioneering. The first proposal for a Brazilian national park aimed at providing a pristine environment to "future generations", just as "it had been created by God" and endowed with "all possible preservation, from the beautiful to the sublime, from the picturesque to the awesome" and "an unmatched flora" located in the "magnificent Iguaçú waterfalls". These were the words used by Andre Rebouças, an engineer, in his book "Provinces of Paraná, Railways to Mato Grosso and Bolivia", which started up the campaign aimed at preserving the Iguaçu Falls way back in 1876, when Yellowstone, the first national park on the planet, was four years old.

On the Brazilian side there is a beautiful walkway along the canyon with an extension to the lower base of the Devil's Throat. Helicopter rides offering aerial views of the falls are available only on the Brazilian side; Argentina has prohibited such tours. From Foz do Iguaçu airport the park can be reached by taxi or bus to entrance of the park. There is an entrance fee to the park on both sides. Free frequent buses are provided to various points within the park. The town of Foz do Iguaçu is about 20 kilometres (12 mi) away and the airport is in between the park and the town.

The Argentine access is by a Rainforest Ecological Train. The train brings visitors to the entrance of Devil's Throat as well as the upper and lower trails. The Paseo Garganta del Diablo is a one-kilometer-long trail that brings the visitor directly over the falls of the Devil's Throat. Other walkways allow access to the elongated stretch of falls on the Argentine side and to the ferry that connects to San Martin island.

The new Brazilian transportation system aims at allowing the increase in the number of visitors while reducing the environmental impact through the increase in the average number of passengers per vehicle inside de Park. The new transportation system boasts new 72 passenger panoramic view double deck buses. The upper deck is open, which enables visitors to enjoy added interactivity with the environment and a broad view of the flora and fauna during the trip to the Falls. The buses combustion system is in compliance with the CONAMA (phase IV) and EURO (phase II) emissions and noise requirements. The reduction in the number of vehicles, of noise levels and of speed is enabling tourists to observe increasing numbers of wild animals along the route. Each bus has an exclusive paint scheme, representing some of the most common wild animals found in the Iguaçú National Park. Some of those are: the spotted jaguars, butterflies, raccoons, prego monkeys, coral snakes, toucans, parrots and yellow breasted caimans.
