Cataratas do Iguacu, known in English as Iguacu Falls, is a vast series of waterfalls on the Iguacu River where Brazil meets Argentina in the far south of the country. The Brazilian side lies within Iguacu National Park in Parana State and faces the Argentine park across the gorge, giving visitors long, panoramic views of water dropping in stages along the basalt escarpment.Iguacu Falls
A waterfall system on a continental scale
The core of Cataratas do Iguacu is a continuous belt of falling water stretching for about 2.7 km (1.7 miles) along the edge of the Iguacu River as it reaches the border plateau.continuous belt of falling water The river narrows and breaks around rocky and wooded islands so that the flow divides into many separate curtains, some narrow and thread-like, others wide enough to resemble individual cliffs of water.
The drop itself ranges from around 60 m (197 ft) to more than 80 m (262 ft), high enough for the water to turn to spray before it reaches the gorge below.ranges from around 60 m to more than 80 m In total there are hundreds of distinct waterfalls arrayed along the escarpment, creating a broken curtain rather than a single drop. The best-known section is Garganta do Diabo, “Devil’s Throat”, a deep recess at the centre of the system where the river pours into a narrow chasm with a particularly high and concentrated fall.Garganta do Diabo
Iguacu National Park and the Atlantic Forest
On the Brazilian side Cataratas do Iguacu lies inside Iguacu National Park, a protected area in Parana that was formally established in 1939 and recognised as a natural World Heritage Site in 1986.established in 1939 and recognised as a natural World Heritage Site in 1986 The park covers tens of thousands of hectares of remaining Atlantic Forest, one of Brazil’s characteristic biomes, and provides a habitat for species ranging from small forest birds to larger mammals such as tapirs and capybaras.
Close to the falls, the vegetation thrives in the constant moisture from spray rising from the gorge, creating dense green slopes that contrast with the bare rock at the lip of the escarpment.spray rising from the gorge Trails and viewing platforms pass through this forest edge, where trunks, lianas and epiphytes frame glimpses of the river and the line of white water beyond. The protected status of the park on both sides of the border means the landscape around the waterfalls remains largely free of development, with the infrastructure concentrated along designated access routes.
Experiencing the Brazilian side of the falls
From Foz do Iguacu the main access road leads through the park towards a series of viewpoints that gradually reveal more of Cataratas do Iguacu. The Brazilian vantage points are set to one side of the river bend, making it possible to see the entire amphitheatre of falls at once, including Garganta do Diabo in the distance.amphitheatre of falls Walkways carry visitors out over the water near the base of some cascades, while higher terraces sit closer to the forest canopy.
The sound of water is constant, rising from the gorge as the Iguacu River drops in stages before flowing on towards its junction with the Parana River.junction with the Parana River Spray drifts across the nearest viewing paths, and on clear days rainbows form in the mist above the lower falls. On the Brazilian side, organised boat trips operate on the river below the escarpment, approaching some of the cascades from downstream, while road vehicles and park buses link the entrance area with the start of the walking route.
