Iguazu falls panoramic

Iguazu Falls, straddling the border between Brazil and Argentina, form one of the world's most spectacular waterfall systems, with 275 drops stretching nearly 3 km.

About this subject

Iguazu Falls are situated within Iguazu National Park in Paraná state (Brazil) and Iguazú National Park in Misiones province (Argentina). The waterfall system originates from the Iguazu River, which rises in the Serra do Mar mountains in Paraná and flows approximately 1,320 km before joining the Paraná River. The waterfalls have been a UNESCO World Heritage site since 1986 and were named one of the New7Wonders of Nature in 2011.

The largest cascade is the Devil's Throat (Garganta do Diabo), 82 meters high, located exactly on the border between the two countries. Visitors can explore catwalks and platforms that offer close-up views of the falls from both the Brazilian and Argentine sides. The average flow rate is around 1,500 cubic meters per second, but can reach up to 6,500 m³/s during flood seasons. The sheer volume creates a constant mist visible from miles away, often producing vivid rainbows.

The region is a biodiversity hotspot, hosting species such as the broad-snouted caiman, jaguar, capuchin monkey, and numerous birds like toucans and hawks. The Brazilian national park covers around 185,000 hectares and represents one of the largest remnants of the Atlantic Forest in the country. Annual visitation exceeds 1.5 million people, driving the local economies of Foz do Iguaçu and Puerto Iguazú. The falls have also been featured in films such as 'Indiana Jones: Raiders of the Lost Ark' and 'The Mission'.

The name 'Iguazu' derives from the Tupi-Guarani words 'y' (water) and 'ûasu' (big), meaning 'big water'. European discovery dates to 1541 when Spanish explorer Álvar Núñez Cabeza de Vaca encountered the falls. Today, the area offers helicopter rides, eco-trails, and is one of South America's most visited tourist destinations.
