Are the Iguazú Falls open today?

When the parks open, when they close, and how to check the status live
Before you go, see if the parks are open and in what condition — straight from the border.
Quick answer: Yes. The Iguaçu National Park (Brazilian side) and the Argentine side open every day of the year. The walkways and the Devil's Throat only close in rare cases of a strong Iguaçu River flood. Before going, check the river level and the rainbow chance live on Marco Três.
When can they close?
Closures are rare and almost always due to a strong Iguaçu River flood, which can shut walkways or the Devil's Throat for safety. On a normal day both sides operate — even in the rain.
