Timing makes all the difference in Iguazu Falls. 275 waterfalls straddling Brazil and Argentina — one of the New 7 Wonders of Nature. Here is what US & Mexican travellers should know about the seasons.
The short answer
The falls run year-round; the water is highest December–March, while May–September brings cooler, drier and more comfortable walking weather.
What makes Iguazu Falls special
- The Brazilian side gives the panoramic view; the Argentine side puts you on top of the falls at the Devil's Throat.
- The Devil's Throat is an 80-metre-high, U-shaped chasm where half the river's flow plunges at once.
- An ecological jungle train carries visitors to the Argentine walkways.
- The surrounding rainforest is home to toucans, coatis and hundreds of butterfly species.

US and Mexican passport holders should note Brazil reinstated an e-Visa requirement for US citizens — Argentina and Chile are visa-free; confirm current rules before travel.
