This spectacular semicircular waterfall that forms the border of Argentina and Brazil spans almost 300 meters in diameter and up to 80 meters in height.

It borders Argentina, where the Iguazu National Park, which was implemented in 1934, is located. The border between the two countries and their national parks is made by the Iguaçú river, whose source is near the Serra (mountain range) do Mar near Curitiba and runs for 18 km throughout the state of Paraná. The river estuary is located 18 km downriver from the Falls, where it flows into the Paraná river. This meeting of rivers forms the triple Brazil, Argentina and Paraguay border.
