Worth it: yes. Travelers routinely name it the highlight of their trip to Argentina. The park was listed as a UNESCO World Heritage site in 1984 and the falls were voted one of the New Seven Wonders of Nature in 2011, and about 1.5 million people visit each year. Rather than take our word for it, read what travelers who did this exact day tour said.
Crowded: sometimes, and it is better planned around than wished away.
When the park fills up
- January and February are the busiest months of the year, Argentine summer holidays
- Long weekends spike sharply
- December, counter-intuitively, stays surprisingly light
- Weekdays are quieter than weekends in every month
The pinch point is Devil’s Throat. It is the park’s signature walkway, everyone wants it, and the ecological train that reaches it moves a fixed number of people per departure.
The move that fixes most of it
Do Devil’s Throat first, at opening. The crowd builds through the morning and peaks near midday, so the same walkway is a completely different experience at 9:30 am than at 1 pm.
This is where an organized day has an accidental advantage. It is built around the earliest flight, so you reach the gates as the park opens and Devil’s Throat is the first stop on the itinerary, you get the quiet version without having to plan for it.
