Iguazu Falls keeps key walkways closed after 13 October

At Iguazu Falls (Cataratas del Iguazú), authorities restricted access to major viewing routes after high water on 13 October 2026, affecting visitors on both the Brazilian and Argentine sides. The measures concern the cross-border waterfall system beside Foz do Iguaçu in Brazil and Argentina.

Flood restrictions reach Iguazu Falls viewpoints in October

The restriction followed a rapid rise in the Iguazu River after heavy rainfall linked by authorities to the El Niño climate pattern. On 12 October, the river exceeded 12,000 cubic metres per second, more than six times its usual average, and Argentina’s Iguazú National Park temporarily restricted access to public-use areas.

Restrictions continued into 13 and 14 October as officials monitored the river and the safety of visitor infrastructure. The 13 October restrictions covered Argentina’s Upper and Lower circuits, while the Brazilian operator restricted access to the suspended walkway leading towards the centre of the falls. The São João Circuit and Espaço Usina were also affected on the Brazilian side.

The Devil’s Throat circuit remains a separate long-term access issue. Park authorities removed sections of its walkway in August as a precaution against flood damage, meaning that a national park can be open while one of its best-known approaches remains unavailable.

UNESCO waterfall links Brazil and Argentina

The falls form a broad semicircle on a basaltic line along the international border. UNESCO describes the waterfall as about 80 metres high and 2,700 metres wide, with the river dropping in a series of cascades across the two national parks.

The Argentine park was inscribed on the World Heritage List in 1984, while the Brazilian Iguaçu National Park followed in 1986. The UNESCO description of Iguazu National Park places the Argentine site in Misiones Province and identifies the adjoining Brazilian park in Paraná as part of the same natural setting.

This geography explains why the October restrictions were reported as a shared visitor issue rather than an isolated closure. A rise in the river can affect bridges, balconies and trails on either side, while each national park and its operator makes separate safety decisions.

The 12 October closure report recorded that the Argentine park’s administration and its operating company had restricted access after the river crossed the safety threshold. It also noted that the Devil’s Throat section had already been closed and its walkways removed in August.

• The site lies beside Foz do Iguaçu in Paraná, Brazil, and Puerto Iguazú in Misiones, Argentina, on opposite sides of the international border.
• Travellers should expect exposed walkways, bridges and viewing balconies near the water, with access to individual routes dependent on river conditions and technical inspections.
• Portuguese is the official language in Brazil and Spanish in Argentina; the national currencies are the Brazilian real and the Argentine peso.
