Iguazu Falls
The world's most powerful waterfall amphitheater thundering amid lush subtropical rainforest.
Geographic Essence & What Makes It Unique
Stretching in a vast 2.7-kilometer crescent along the border of Argentina and Brazil, Iguazu consists of between 150 and 300 individual waterfalls, depending on river flow. Plunging into the geological fault of the "Devil's Throat" (Garganta del Diablo) with an average discharge exceeding 1,500 cubic meters per second, the falls generate perpetual rainbow-crowned mist plumes. Surrounded by the Atlantic Forest, the parks shelter over 2,000 plant species, toucans, coatis, and brilliantly colored tropical butterflies.
