Situated in the Parque Nacional Iguaz˙ near Puerto Iguaz˙, these spectacular falls lie just east of the confluence of the Iguaz˙ and Paranß rivers. At least 5000 cubic m (176,570 cu ft) of water per second plunge the 70m (230ft) into the abyss below.
If they look familiar, it's because they were the supporting actors in the film The Mission; appropriately, the area has historic ruins of Jesuit missions which also draw many visitors.
San Ignacio MinÝ, built in a style of architecture known as 'GuaranÝ baroque', is especially popular. Above the falls, the waters are suitable for canoeing, kayaking and other water sports. The surrounding park is home to 55,000 hectares (135,850 acres) of pristine subtropical rainforest, with abundant wildlife and plant species.
