Devil’s Throat


The Devil’s Throat, the park’s most iconic waterfall, is reached via an ecological train and accessible walkways. In spring, the river levels are high, creating an impressive flow and frequent rainbows in the mist. This is one of the most sought-after experiences for international travelers and nature lovers.


Beyond the classic circuits, the Argentine side of Iguazú National Park offers activities for direct contact with the subtropical forest. Visitors can explore interpretive trails that explain the local flora and fauna — orchids, giant ferns, and native trees. Guided bird- and butterfly-watching tours are also available, ideal for families and those interested in local biodiversity.


Boat rides through the Iguazú River rapids bring visitors close to the base of some of the park’s most powerful waterfalls. For adventure seekers, some operators offer treks combined with rafting through less-visited areas, always with certified guides and safety equipment.
