Iguazu Falls are several waterfalls that are found on the Iguazu river, on the border of Argentina and Brazil. Together, these waterfalls form the largest such system in the world. The waterfalls divide the Iguazu river into the upper and lower Iguazu, depending on whether the river is measured before the waterfalls, or after them.
Every year, tens of thousands of tourists visit the Iguazu Falls. In total, there are 275 different cascades, with the tallest one being 80m. Although not as well-known as the Niagara Falls, the Iguazu has said to be the best spectacular sight of its kind, so if you're in the neighborhood (touring South America) you should definitely try to check out this spot located on the border between Brazil and Argentina.
