Iguazu Falls walkway closed due to increased flow

Trail remains open; reopening depends on water volume drop
The Iguazu Falls walkway in Iguazu National Park, located in Foz do Iguaçu, was closed preventively on Friday, September 11, at 1 p.m. because of the rising flow of the Iguaçu River. The measure follows the conservation unit’s safety protocols.
The flow reached 8.4 million liters per second at the time of the closure, with forecasts indicating it could rise above 9 million liters per second by late afternoon. For comparison, the historic average flow of the Falls is about 1.5 million liters per second.
The increase results from rainfall in the Iguaçu River basin, which may be linked to the El Niño phenomenon that brings higher precipitation in September.
Reopening of the walkway will depend on the flow decreasing to levels considered safe, with no set date. The Falls Trail and its viewpoints remain open to the public, allowing visitors to view the cascades during the temporary walkway shutdown.
The Bananeiras and Poço Preto paths were also temporarily closed due to flood risk. Tourist visitation in the park continues normally until 4 p.m.
The technical team of the concessionaire Urbia+Cataratas and the Chico Mendes Institute for Biodiversity Conservation (ICMBio) are monitoring the situation in real time. For updates on flow and park operations, visit the official WhatsApp channel: https://chat.whatsapp.com/DXgbgHia63M5xn8IOHXVjP
