Insta / natgeotravel: Photo by // Iguazu Falls along the border of Argentina and Brazil is the most impressive waterscape I have ever seen. The falls are nearly 3 km wide and flow enough water to fill 5 Olympic swimming pools every second.
Iguazu Falls are waterfalls of the Iguazu River on the border of the Brazilian state of Paraná and the Argentinian province of Misiones. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba.
