The Iguazu Falls and National Park are located ten miles from Puerto Iguazu. The deep flowing waters of the river fall from a height of 30 feet through 275 falls over one and a half mile. The frontier with Brazil goes through the Garganta del Diablo (Devil's Throat) where the falling water gives the illusion of magic rainbows. The National Park is full of the exotic subtropical vegetation which surrounds the falls and has 2.000 plant species - gigantic trees, ferns, lianas, orchids; 400 bird species - parrots, colibries, toucans; jaguars and yacarés (caimans).

South of Iguazu Falls is the Ibera Estuary, the second largest wetlands in South America. The Estuary is home to several endangered species and over 350 bird species. The region is rich with impressive biodiversity that demonstrates the beauty of a balanced ecosystem. Located nearby is the UNESCO World Heritage Site of San Ignacio Ruins, a settlement site of converted Guarani founded by the Jesuits.
