Iguazú National Park

Iguazú National Park on the Argentine side protects the southern portion of the Iguazú Falls system on the Iguazú River, a UNESCO World Heritage Site famed for its extensive cascade complex. The fall system comprises roughly 275 separate drops spread over about 2.7 kilometers.

A network of elevated walkways provides both panoramic and intimate views of the falls, including routes that lead to the rim of the iconic Garganta del Diablo (Devil’s Throat), an 82-meter-deep chasm where multiple streams converge. Boat excursions and river-front viewing areas allow visitors to experience the power of the falls from river level and from set viewing points near the town of Puerto Iguazú.

The park supports subtropical rainforest with high biodiversity, offering wildlife sightings along trails and at observation points, and visitor facilities centered around the main access roads and park entrances.

The falls and surrounding forest have long been inhabited by indigenous peoples; the Argentine park was established to conserve the falls and the surrounding rainforest and was listed as a UNESCO World Heritage Site for its outstanding natural phenomena and biodiversity. Cross-border cooperation with Brazil preserves the larger Iguazú/Iguaçu ecosystem.

Located in Misiones Province in northeastern Argentina, the park borders Brazil across the Iguazú River and lies adjacent to the town of Puerto Iguazú, forming the Argentine approach to the larger falls system.

• UNESCO and scale: Inscribed as a UNESCO World Heritage Site, the park contains about 275 separate drops stretching roughly 2.7 kilometers, with the most dramatic plunge at the Devil's Throat (about 82 meters).
• Access and experiences: A system of secure walkways and viewing platforms on the Argentine side brings visitors close to many falls, while boat excursions operate from river terminals to approach the bases of selected cataracts.
