Argentina - Iguazú Falls

The Iguazú Falls are waterfalls of the Iguazú River on the border of Argentina and Brazil. They are the largest waterfalls system in the world. The Iguazú River rises near the Brazilian city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side.

The Iguazú Falls are located where the river tumbles over the edge of the Paraná Plateau. The edge has a length of 2,7 kilometers and numerous islands divide the falls into many separate waterfalls and cataracts, varying between 60 to 82 meters high. The number of these smaller waterfalls fluctuates from 150 to 300, depending on the water level. Approximately half of the river's flow falls into a long and narrow chasm, called the Devil's Throat (PiP 1).
