Brazil/ Argentina: Iguaçu Falls

Iguazu Falls are waterfalls of the Iguazu River on the border of the Argentina province of Misiones and the Brazilian state of Paraná. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba. For most of its course, the river flows through Brazil, however, most of the falls are on the Argentine side.
