The Iguazu River and are located on the border of Brazil (in the state of Paraná) and Argentina. In fact, the Iguazu Falls are what divides the river of the same name into its upper and lower portions, a fact that has given rise to several myths and legends as to their origin. This river forms the boundary between Brazil and Argentina, making it a significant part of the political and geographical structure of the continent of South America.
The name of the falls originates from the Tupi or Guarani language, and means “big water”. While the ancient Brazilian tribes knew of its thunderous beauty, it was only officially ‘discovered’ in 1541, when the European explorer, the Spanish Conquistador Álvar Núñez Cabeza de Vaca, came across its awe-inspiring beauty. Today, the Iguazu Falls are owned by the two UNESCO World Heritage Sites: the Iguazú National Park in Argentina and the Iguaçu National Park in Brazil.
