Cataratas del Iguazu: a vast curtain of water above the jungle
Published on 08/15/2026 at 14:45 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Cataratas del Iguazu is a wide belt of waterfalls where the Iguazu River drops over the edge of the Paraná Plateau, forming a broken curtain of water between Argentina and Brazil. The falls are part of Iguazu National Park on the Argentine side, near the town of Puerto Iguazu in Misiones Province, and face Iguaçu National Park in Paraná State in Brazil.Iguazu Falls on the Iguazu River
A waterfall system spread across a basalt cliff
Cataratas del Iguazu is not a single drop but a system of many falls distributed along the rim of a basalt plateau, where hardened lava forms a vertical escarpment. Across several kilometres the Iguazu River reaches the cliff edge and plunges in separate curtains, broken by islands and rocky outcrops, so that water appears in discrete bands rather than as one continuous wall.a set of 275 falls Basaltic volcanic rocks laid down in the Lower Cretaceous period shape the rim, giving the whole scene a dark, solid frame for the pale water.fissural basaltic volcanic rocks
The waterfall front stretches for roughly 2.7 km (1.7 miles), with individual drops varying in height between about 60 m and 82 m (197–269 ft), figures that place Cataratas del Iguazu among the largest waterfall systems in the world by width.a 2.7 kilometre-wide front The river above the cliff is comparatively broad and calm, but once it reaches the edge it divides into channels that feed separate waterfalls, some narrow and concentrated, others broad and fan-like. Looking across from walkways and viewpoints, the eye follows bands of falling water broken by patches of forest, bare rock and rising spray.
Devil’s Throat and the horseshoe of water
Within Cataratas del Iguazu, the section known as Devil’s Throat (Garganta del Diablo) forms a deep, U-shaped chasm where roughly half of the river’s flow plunges into a narrow gorge. This feature stands about 82 m (269 ft) high, with a width of around 150 m (492 ft) and a length close to 700 m (2,297 ft), concentrating water into a single, dramatic drop.Devil’s Throat dimensions Mist rises from the base of the chasm and often obscures the far side, so the upper rim appears as a broken ring around a cloud of spray.
The main cataract at Cataratas del Iguazu forms a broad horseshoe where water wraps around the gorge, a central feature of the falls’ layout. The combined horseshoe cataract is around 72 m (236 ft) high and extends for about 2,700 m (8,858 ft), with a portion of this length lying on the Brazilian side of the border.a central horseshoe cataract From Argentine walkways the curve of the horseshoe is visible in stages, while from Brazilian viewpoints visitors see the arc of falls face-on, with the river bending sharply before reaching the precipice.
River, rainforest and protected status
Cataratas del Iguazu sits within subtropical rainforest at the northern tip of Argentina’s Misiones Province, where the Iguazu River forms a natural boundary with Brazil. The river is a tributary of the Paraná, and the falls lie roughly 23 km (14 miles) upstream from the confluence of the two rivers, at a point where the plateau ends and the water descends into a canyon.location above the Parana The surrounding forest is dense, with evergreen trees, lianas and undergrowth covering much of the plateau and valley.
On the Argentine side, Cataratas del Iguazu forms the core of Iguazu National Park, which was inscribed as a UNESCO World Heritage Site in 1984 for its natural qualities and biodiversity.UNESCO inscription in 1984 Across the river, Brazil’s Iguaçu National Park holds a corresponding designation, granted in 1986, so the protected area extends on both sides of the border.World Heritage status in Argentina and Brazil Within these parks, trails, boardwalks and viewing platforms bring visitors close to the falls, while the broader reserve protects forest, riverside habitats and basalt outcrops.
