Iguazu Falls is located at the junction of three nations: Brazil, Argentina, and Paraguay. These “Great Waters,” as named by the indigenous Guarani people, are made up of 275 waterfalls that span nearly 2 miles. Sorry, Niagara! Any Iguazu Falls tour will provide you with a sense of nature’s power and wonder. You can follow a boardwalk trail and take in the majestic, roaring falls from a safe vantage point…or, if you feel daring, a platform above the falls. Look down, but hang on to the railing—that’s a lot of water pouring beneath you.
