Things to do
5-
Devil's Throat
Fourteen falls converge into one U-shaped chasm where half the river drops at once, throwing spray high enough to soak the walkway. A long catwalk over braided water leads to the platform, reached by the park train or on foot along the tracks. Early trains fill, and booking the slot on arrival avoids a long wait.

Güirá Oga
A rescue centre in the forest on the road to the park, holding birds injured by traffic, power lines and the pet trade, among them harpy eagles and macaws. Visits are guided along a forest trail and last around an hour. The work is rehabilitation and release, so enclosures are large and sightings are never guaranteed.
-
Hito Tres Fronteras
A painted obelisk on a bluff above the confluence marks the point where Argentina, Brazil and Paraguay meet, with matching markers visible across each river. The setting is a small plaza of craft stalls and a viewpoint terrace. Sunset is the moment to be there, and the visit takes twenty minutes at most.
-
Iguazú Falls
Some two hundred and seventy cascades break over a horseshoe of basalt more than two kilometres wide, split between Argentina and Brazil and ringed by subtropical forest. The Argentine side runs catwalks out over and under the water, while the Brazilian side gives the panorama. Flow varies sharply with rain, and a swollen river closes the lower walkways.

Iguazú National Park
Beyond the catwalks, subtropical forest holds toucans, capuchins and, rarely seen, jaguar and tapir. Coatis work the picnic areas and will open an unattended bag, which is why feeding them is banned and the ban is enforced. Entry is ticketed for a single day, and a second consecutive day can be added at the gate before leaving.
