Iguazú Falls, one of the new 7 wonders of nature is definitely worth a visit. We preferred the Argentina side and spent 2 days walking trails there. It’s about a 30 minutes bus ride from the bus depot in Puerto Iguazu to the national park entrance.
As suggested we did the 1700 metre lower circuit trail first. It was definitely the most spectacular. Although the upper trail was also breathtaking since it takes you to the top of the falls where you walk across walkways giving you a sensation of almost going over the falls. There is also a train that takes you to an even higher location or you can take it down and get off near the park exit.
Depending on when you go, bring lots of water to drink or to pour on yourself to cool down from walking long distances in high heat and humidity.
On the 2nd day we did the Sendero Macuco trail a 4.5k walk one-way into a small waterfall with a pond at the end. We stopped there to eat lunch and cool our legs in the water before returning. It was a beautiful, shady and peaceful trail where we saw some interesting spider webs, insects, birds and foliage. Unfortunately no toucans which can sometimes be spotted along the way. In other areas of the park we saw monkeys, coatis, lizards and lots of beautiful butterflies.
If you stay in Puerto Iguazu you need to cross the border into Brazil which requires extra time and shortens your day at the falls. As of 2019, Canadians and Americans do not need a visa to enter so that makes the trip easier to do and less expensive. Make sure you check if you need a visa before attempting to cross the border
There are also boat trips to the falls that make sure you get wet, as well as helicopter rides so you can see it all from the air. So try to add Puerto Iguazu to your Argentina travel itinerary, I don’t think you will be disappointed.
