Iguazu Falls

Located at the “triple border” between Argentina, Brazil, and Paraguay, the Iguazu region has the most impressive network of waterfalls in the world.

Accessible from both Argentina and Brazil and in the middle of a dense, luxuriant rainforest, there’s a reason the falls were selected as one of seven “Natural Wonders of World” in 2011 and UNESCO declared them a World Heritage Site in 1984.

Be ready to move across the Argentina–Brazil border, and don’t miss the Garganta del Diablo (Devil’s throat), the Falls’ gargantuan centerpiece. Though the central chute of the falls falls technically on the Brazilian side, the Argentina viewing platform is better located.
