Cataratas do Iguacu, known in English as Iguazu Falls, form an immense series of waterfalls on the Iguacu River at the border between southern Brazil and northern Argentina. The cascades lie near the city of Foz do Iguacu in the Brazilian state of Parana and spread in a broad arc across a basalt plateau where the river drops abruptly towards the Parana River basin.
The great bend of the Iguacu River
The Iguacu River flows westward across Parana before turning towards the border and plunging over a basalt escarpment, creating Cataratas do Iguacu as it approaches its confluence with the Parana River.Iguacu River The falls extend for around 2.7 km (1.7 miles) in length, forming a broken line of separate drops and curtain-like segments along the gorge.2.7 km in length
The series comprises about 275 individual waterfalls, varying in width and height as the river splits around islands at the edge of the plateau.about 275 individual waterfalls Many of these falls drop from heights between roughly 60 m and 82 m (197–269 ft), giving the whole system a multi-level character as water thunders into the narrow canyon below.heights between 60 m and 82 m
Devil’s Throat and the surrounding cascades
The most dramatic sector of Cataratas do Iguacu is a deep recess in the gorge known as the Garganta do Diabo, or Devil’s Throat. Here the river concentrates into a U-shaped chasm where several major waterfalls converge, including the highest continuous drop of the system, which reaches about 82 m (269 ft) from rim to river surface.Devil’s Throat sector The gorge at this point is significantly wider than elsewhere along the canyon, and its vertical walls rise steeply from the swirling foam below.
Around Devil’s Throat the water falls in powerful curtains that send spray up towards the forested rim, while narrower side channels feed smaller drops along the cliff. Wooden walkways and terraces on the Brazilian side stand on solid supports above the riverbank, bringing visitors close to several major cascades without entering the water itself.walkways and terraces
A protected subtropical forest landscape
Cataratas do Iguacu lie within Iguaçu National Park, a protected area in Parana State created by federal decree on 10 January 1939.Iguaçu National Park The park covers a large tract of Atlantic Forest, a subtropical rainforest biome that once extended across much of Brazil’s southern and coastal regions. Its Brazilian area has been measured at over 169,000 hectares, forming a broad buffer of woodland, river and canyon around the falls.169,695.88 hectares
The Brazilian park stands opposite Argentina’s Iguazu National Park, and together these two protected areas form a transboundary World Heritage site recognised by UNESCO since the mid-1980s.World Heritage recognition The forest around the falls supports a range of plant and animal species typical of the Atlantic Forest, including broadleaf trees, epiphytes and mammals adapted to humid woodland, all arranged along the steep topography carved by the Iguacu River.
Names, meanings and human presence
The name “Iguacu” comes from the Tupi-Guarani language and is widely understood to mean “big water”, referring to the scale of the river and its cataracts.meaning of Iguacu In Portuguese the falls are called Cataratas do Iguaçu, while the Spanish form Cataratas del Iguazu is used on the Argentine side and in neighbouring regions.Portuguese and Spanish names Early European encounters with the falls are associated with the Spanish explorer Álvar Núñez Cabeza de Vaca, who reached the area in 1542 and reported on the immense waterfalls along the river.Álvar Núñez Cabeza de Vaca
On the Brazilian side the gateway city is Foz do Iguacu, which lies in Parana close to both the Argentine border and the frontier with Paraguay.Foz do Iguacu gateway Access roads lead from the city towards the park entrance, where visitors transfer to internal park transport or walk along designated routes through forest and viewpoints. The contrast between the built-up urban area and the sudden drop into canyon and spray emphasises how sharply the Iguacu River has cut its path through the plateau.
