Hundreds of Waterfalls on Two Countries' Border

Iguazu Falls is a vast system of waterfalls on the Iguazu River, which forms the border between Argentina and Brazil. Depending on the water level, there are about 275 individual drops spread along nearly 3 kilometers. The name comes from Guaraní words meaning big water.

The most dramatic section, the Devil's Throat, is a U-shaped chasm where water plunges with a roar and rising mist. National parks on both sides protect the falls and surrounding rainforest, and both are UNESCO World Heritage Sites. Eleanor Roosevelt is said to have exclaimed Poor Niagara on seeing them.

The Argentine side has walkways that bring visitors close above and below the falls, while the Brazilian side offers sweeping panoramic views. Coatis, raccoon-like animals, roam the trails looking for snacks. Nearby, the Triple Frontier marks where Argentina, Brazil and Paraguay meet.
