Iguazu Falls, Argentina/Brazil

Iguazu Falls is a system of 275 individual drops stretching 2.7 km along the Iguazu River, with the central Devil's Throat canyon plunging 82 m and measuring 150 m wide. Its average flow of 1,756 m³ per second can surge past 12,000 m³ per second during floods—a power that dwarfs Niagara Falls' typical 2,400 m³/s by over 400%. The Argentine side offers catwalks above and below the falls for an intimate roar, while the Brazilian side provides the iconic panoramic arc best photographed at sunrise. Compared to Angel Falls, Iguazu offers far greater biodiversity and accessibility, with over 2,000 plant species thriving along the trails and 50% more annual visitors.
