Iguazu Falls are waterfalls existing on the border of Argentina and Brazil. Together, they make up the largest waterfall in the world. The falls divide the river into the upper and lower Iguazu. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side.
The name “Iguazú” comes from the Guarani or Tupi words “y” , meaning “water”, and “ûasú meaning “big”. Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers to an eternal fall.
The actual number of waterfalls fluctuates depending on the water level and how much water is flowing. The number ranges from 150 to 300 falls at any given time. The Falls is also a UNESCO World Heritage Site.
