Argentina dismantles Devil's Throat walkway due to flood risk
Marco Três newsroom · edited by Annie Grellmann
Structure will be removed in Puerto Iguazú until river flow decreases
The access walkway to Devil's Throat in Iguazú National Park in Puerto Iguazú, Argentina, began to be dismantled on Monday, August 3, because of forecasts of increased flow of the Iguaçu River in the coming months, linked to the El Niño phenomenon. The decision was made by the Argentine National Parks Administration and Iguazú Argentina, the park concessionaire.
Preventive dismantling
The flooring and handrails of the circuit will be removed and stored at the Devil's Throat railway station for preservation. According to the newspaper Clarín, the removal should take about 40 days, while the subsequent reassembly will require at least 60 days of work.
Forecast of high flows
Climate and hydrological monitoring indicate high flows expected for September and October, with the potential to cause extraordinary floods that could damage the infrastructure. The Iguaçu River basin is almost entirely in Brazil (98%) with a small portion in Argentina (2%), which leads to a rapid rise in flow when heavy rains occur. The week before, the walkway had already been closed for three days when the flow reached nearly 10,000 cubic meters per second.
Reopening with no set date
There is no forecast for reopening before the end of 2026, as the flood peak is expected in September and October. The schedule will be drawn up based on information received from Brazil. Visitors can still access the falls from the Argentine side via the lower and upper circuits of the park. No changes are planned on the Brazilian side.
About El Niño
The phenomenon occurs when the surface waters of the Central and Eastern Equatorial Pacific remain persistently warmer than average, altering tropical atmospheric circulation. In southern Brazil, the effects include above-average rainfall, more frequent thunderstorms, and more frequent river floods.
