The Day Visitor's Brief
Some visitors see Iguazú Falls as a single long day, often as part of a wider regional trip.
Priority one
Arrive at opening if you want to cover all three circuits comfortably in one day.
A realistic single day
Garganta del Diablo first, then Circuito Superior, then Circuito Inferior — the planner's default order.
What to pack
Rain-ready clothing and footwear — spray from the falls reaches several of the walkways.
Before you arrive
Check current park hours and whether advance tickets are recommended.
