Argentina caps daily visitors at Iguazú Falls to protect ecosystem

The administration of Parque Nacional Iguazú announced a new resolution limiting tourist access to a maximum of 8,000 visitors per day on the Argentine side of the falls, effective August. The measure responds to documented erosion of walkways and stress on local wildlife caused by mass tourism, especially around the Garganta del Diablo. Travel agencies and international tour operators must now book entries at least two weeks in advance through a digital platform that assigns tickets to specific visitors, includes ID verification, and eliminates on‑site ticket sales.

Park rangers and biologists say the cap aims to balance economic benefits with environmental preservation, encouraging higher‑value, eco‑conscious travelers while reducing crowding and habitat disturbance. The new system also seeks to prevent resale and black‑market tickets, and local hotels are promoting longer stays to offset any potential revenue loss.
