This spectacular chain of waterfalls, which spans 3 km (1.85 miles) and is bordered by subtropical rainforest, is one of the world’s greatest natural wonders. It is shared by Argentina and Brazil. Visitors may get a close-up view of the more than 250 cascades and cataracts in the nearby national park thanks to its extensive network of trails, walkways, and bridges. The Garganta del Diablo (“Devil’s Throat”), a roiling mass of white water that emits a deafening scream and shoots up massive clouds of spray, serves as the attraction’s focal point.
