Iguazu falls panoramic

Panoramic view of Iguazu Falls, one of the largest waterfall systems in the world, on the border between Brazil and Argentina.

About this subject

Iguazu Falls consists of approximately 275 individual waterfalls along the Iguazu River, straddling the border between the Brazilian state of Paraná and the Argentine province of Misiones. The system stretches about 2.7 kilometers and drops up to 82 meters, ranking among the world's largest and most impressive waterfall complexes. The most powerful section, known as Devil's Throat (Garganta do Diabo), features a massive cascade that generates constant mist and rainbows.

Protected within Iguazu National Park (Brazil) and Iguazú National Park (Argentina), the falls have been a UNESCO World Heritage site since 1986. The surrounding subtropical rainforest is one of the largest remaining fragments of the Atlantic Forest biome, hosting species such as jaguars, coatis, and over 400 bird species. The name "Iguazu" derives from the Guarani words "y" (water) and "guasu" (big), aptly describing the immense water volume.

First documented by Spanish explorer Álvar Núñez Cabeza de Vaca in 1542, the falls had been sacred to the Guarani people for centuries. They gained worldwide fame through films like 1939's "Tarzan Finds a Son!" and later appeared in movies such as "The Mission" (1986) and "Indiana Jones and the Kingdom of the Crystal Skull" (2008). Today, the area attracts over 1.5 million visitors annually, with well-maintained walkways and viewpoints on both sides offering unique perspectives of the cascades.
