Argentina - Iguazù 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.

Iguaçu National Park is a national park in Paraná State, Brazil.

Created by federal decree nr. 1035 of January 10, 1939, the Park comprises a total area of 185,262.5 hectares and a length of about 420km, 300km of which are natural borders by bodies of water and the Brazilian and Argentinean sides together comprise around 225 thousand hectares.

On November 17, 1986, during the UNESCO conference held in Paris, the Iguaçú National Park was listed as Natural Heritage of Humanity and is one of the largest forest preservation areas in South America.

The Iguaçú National Park owes its name to the fact it includes an important area of the Iguaçú river, approximately 50km of the length of the river and the world famous Iguaçú Falls.

It is the most important park of the Prata Basin and, since it is a haven to a significant genetic asset of animal and vegetal species, it was the first park in Brazil to receive a Management Plan.

The Iguaçú 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 Iguaçú Falls way back in 1876, when Yellowstone, the first national park on the planet, was four years old.

In Brazil the Park has boundaries with the following municipalities: Foz do Iguaçu, Medianeira, Matelândia, Céu Azul, São Miguel do Iguaçu, Santa Terezinha de Itaipu, Santa Tereza do Oeste, Capitão Leônidas Marque, Capanema and Serranópolis.

The Iguazú National Park is a national park of Argentina, located in the Iguazú Department, in the north of the province of Misiones, Argentine Mesopotamia. It has an area of 550 km² (212 sq mi).
