Urbia+Cataratas restricts access at Iguazu Falls on 13 October

Urbia+Cataratas introduced a high-flow safety protocol at Iguazu Falls (Iguaçu Falls) in Foz do Iguacu on 13 October 2026 as the river rose sharply. The Brazilian side of the waterfall system remained open, but several visitor areas were restricted.

High-flow protocol changes access at Iguazu Falls

The concessionaire, which manages tourism services at the Brazilian park, said the Rio Iguaçu reached 10.5 million litres per second on 13 October 2026. The flow had peaked at 11.8 million litres per second on 12 October, the highest level recorded there in 2026.

The main walkway had been closed since 11 October after the river exceeded the safety threshold. On 13 October, crews removed its protective railings to allow water to pass more freely, while the walkway itself stayed closed to visitors. The lower viewpoint at Espaço Naipi, the São João Circuit, Espaço Usina, the Poço Preto path and the Canafístula trail were also restricted. The 13 October safety notice said the Falls Trail remained available.

Under the published protocol, the walkway closes when the flow exceeds 8.5 million litres per second and is still rising. Its railings are removed when the flow is between 9 million and 12 million litres per second with an upward trend. Reopening requires lower water levels, a technical assessment and authorisation from a specialist engineer.

Why the river matters to the Brazilian park

The falls form part of Iguaçu National Park, a protected area administered by Brazil's conservation authority and visited from Foz do Iguacu. The park is listed as a UNESCO World Heritage natural site from 1986.

The federal conservation authority describes the protected landscape as a remnant of Atlantic Forest shaped by volcanic processes dating back 500 million years. The waterfall system extends for almost three kilometres, with vertical drops reaching 80 metres. Those fixed geographic features explain why the current restrictions affect specific walkways and viewpoints rather than closing every visitor route.

The 13 October measures connect the river's exceptional level directly with the areas closest to the water. Visitors can still approach the cascades along the Falls Trail, but cannot use the closed walkway or the listed restricted paths while the protocol applies. The park's World Heritage information records the site's protected status and its physical scale.
