Iguazu Falls are waterfalls of the Iguazu River on the border of Brazilian state Paraná and Argentine province Misiones. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises 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 Argentina and Brazil.
We visit the falls via Brazil and Argentina and you will see the falls walking around the banks and the platforms, but also from a helicopterflight and at the end from an airplane.
The name “Iguazu” comes from the Guarani or Tupi words “y”, 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.
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-long (1.7 mi) edge divide the falls into numerous separate waterfalls and cataracts, varying between 60 to 82 metres (197 to 269 ft) high. The number of these smaller waterfalls fluctuates from 150 to 300, depending on the water level. About half of the river’s flow falls into a long and narrow chasm called the Devil’s Throat (Garganta del Diablo) The Devil’s Throat is U-shaped, 82 metres high, 150 m wide, and 700 m long (269×490×2,300 ft).
Iguazú Falls from the Argentine side
About 900 metres (2,950 ft) of the 2.7-kilometre (1.7 mi) 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 nations can be seen, a popular tourist attraction for visitors to the three cities.
