The waterfalls are part of a 130-million-year-old lava flow formation.
The flow rate can reach 6,500 cubic meters per second during peak flood events.
The falls are wider than both Victoria Falls and Niagara Falls.
The name 'Iguazu' originates from the Guarani words 'y' (water) and 'guasu' (big).
The park protects one of the last remaining remnants of the Interior Atlantic Forest.
The site hosts an estimated 2,000 species of vascular plants.
The Devil's Throat marks the border between the Argentine province of Misiones and the Brazilian state of Paraná.
The spray from the falls creates a microclimate that allows unique mosses and orchids to thrive on the surrounding cliffs.
Iguazu Falls is a complex of 275 individual waterfalls spanning nearly 3 kilometers along the border between Argentina and Brazil. The system is formed by the Iguazu River and features a maximum drop height of 82 meters. The 'Garganta del Diablo' (Devil's Throat) is the most prominent feature, shaped like a U-bend and receiving half the river's flow volume. The site is located within Iguazú National Park, a protected UNESCO World Heritage site and a designated Important Bird Area. The park infrastructure comprises a network of elevated catwalks, including the Upper and Lower Circuits, which provide panoramic and close-up views of the cascades. The basaltic rock formation resulted from volcanic activity approximately 130 million years ago. Humidity levels remain consistently high, contributing to the surrounding subtropical rainforest ecosystem. The park provides access to diverse fauna, including coatis, toucans, and over 400 species of birds.

Bring a waterproof cover for your camera and electronics to protect them from the constant mist.
Wear quick-drying clothing and sturdy, non-slip footwear as the catwalks are frequently wet.
Start your visit at the park entrance as early as possible to minimize congestion at the Devil's Throat station.
Do not carry plastic bags or open food containers, as the native coatis are opportunistic scavengers that frequently snatch items from tourists.
The park remains open year-round, but specific trails may close temporarily due to extreme flooding or high river levels.
Do not feed the wild coatis or other animals; do not step off the marked metal catwalks.
