Cataratas del Iguazu between Brazil and Argentina
Published on 08/25/2026 at 19:57 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Cataratas del Iguazu, also known in English as Iguazu Falls, forms a sweeping curtain of waterfalls on the Iguazu River between Argentina and Brazil. The system stretches for several kilometres along the frontier between the Argentine province of Misiones and the Brazilian state of Paraná, with viewpoints reached from Foz do Iguacu on one side and Puerto Iguazú on the other.waterfalls of the Iguazu River
A crescent of falling water in the subtropical forest
The core impression of Cataratas del Iguazu is scale: instead of a single drop, visitors face a long arc of cataracts broken by islands and cliffs. The waterfall system extends for about 2.7 km (1.7 miles), with water plunging from a basalt edge into a deep gorge cut through the plateau.a 2.7-kilometre horseshoe shape The cliffs and islands divide the river into hundreds of separate falls that vary in height and volume along the rim.
The longest drops reach about 82 m (269 ft), sending white curtains of water down the dark rock face into the lower river.falls varying between 60 and 82 metres In places the river falls in narrow streams; in others the water gathers into broader sheets that throw spray high above the gorge. Forest presses right to the edge on both banks, so that any viewpoint frames the waterfalls with dense subtropical vegetation rather than buildings or roads.
Two national parks, one shared river
Cataratas del Iguazu lies at the heart of two protected areas: Iguazú National Park in Argentina and Iguaçu National Park in Brazil, both established to conserve the remaining Interior Atlantic Forest and the falls themselves.Iguazú National Park in Misiones Province Iguazú National Park was inscribed as a UNESCO World Heritage Site in 1984 for its combination of dramatic landscape and rich biodiversity, and its Brazilian counterpart holds a matching status on the other side of the river.inscribed on the World Heritage List in 1984
On the Argentine bank, a network of walkways and circuits explores different levels of the river and rim inside Iguazú National Park, much of it shaded by forest trees and lianas. On the Brazilian side, the Iguaçu National Park route follows a panoramic path along the canyon edge near Foz do Iguacu, where open viewpoints look back towards the main arc of falls across the gorge. Together the two parks preserve a large tract of subtropical forest, where birds, butterflies and other wildlife still inhabit the ravines around the waterfalls.
Garganta del Diablo and the drama of the gorge
The most striking single feature of Cataratas del Iguazu is Garganta del Diablo, the Devil’s Throat, where the river concentrates into a deep, U-shaped chasm on the border. Here a cluster of cataracts converges and drops about 80 to 82 m into a narrow gorge, sending spray high into the air and masking the lower rock in mist.a U-shaped basalt canyon where waterfalls converge From above, the river appears calm until it reaches the brink, where the water folds over the edge in powerful white streams.
On the Argentine side, Garganta del Diablo is approached within Iguazú National Park by a long, level walkway that carries visitors over the upper river to a lookout at the chasm.a metal walkway from the Ecological Jungle Train From the Brazilian bank near Foz do Iguacu, walkways and platforms at the end of the main trail offer a frontal view into the throat, where the water plunges into the gorge below. The combination of height, confined rock walls and massed water gives this part of Cataratas del Iguazu its most dramatic character.
Visiting Cataratas del Iguazu: what travellers from Western Europe should know
- Cataratas del Iguazu stands on the Iguazu River at the border of Argentina and Brazil, reached through Iguazú National Park from Puerto Iguazú and Iguaçu National Park from Foz do Iguacu.
- The viewpoints sit on the rim of a deep gorge, and many routes use elevated metal walkways and stairways rather than level streets, so walking surfaces can be long and exposed.
- The surrounding landscape is low plateau cloaked in subtropical forest, so paths alternate between open canyon-edge balconies and shaded sections among dense trees and undergrowth.
- The official language in this border area is Spanish on the Argentine side and Portuguese on the Brazilian side, and the currencies are the Argentine peso and the Brazilian real.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
