Iguassu Falls (Brazil/Argentina)
Straddling the border between Brazil and Argentina, Iguassu Falls divides the Iguazu River into upper and lower reaches and comprises 275 individual drops. It is the region’s most-visited attraction, ranks among the world’s tallest waterfalls, and dwarfs Niagara in both width and scale. Its immense power and sweeping vistas make it a must-see for visitors to the area.
