Iguazu Falls tours: Cataratas del Iguazú and Cataratas do Iguaçu compared

The Iguazu river averages between 1,500 and 1,800 cubic meters a second, depending on the source, and reached about 46,000 on 9 June 2014, some 30 times the normal flow the park concessionaire gives. That range is why the walkways to the Devil's Throat close, and why a tour that promises them cannot always deliver. This page is about the falls as a system: how they formed, how the two national parks differ, how the river shuts a walkway and how to read the state of the day. Then it helps you choose among the 80 Iguazu Falls tours we list, which typically cost 120 to 250 EUR. They run from under 60 EUR for a shared day trip to more than 500 EUR for a multi-day package, and they sit on four pages, linked in the cards near the end. Where a figure comes from the parks, from the press or from an encyclopedia and not from our own catalog, the text says so.

A note on the menu. This page sits under Brazil because most tours leave from Foz do Iguaçu, and the site also lists it under Argentina. The falls are on the border and the page covers both sides. The rest of Brazil's waterfalls, and why Iguazu is the only one with tours here, are on the Brazil page. The four tour formats are read one listing at a time on their own pages, each with a price chart and, where it exists, a map. Prices are as listed on 22 October 2026, in euros.
