The Brazilian side of Iguaçu Falls trades the Argentine side's up-close trails for sweeping panoramic views — a short walkway leads to a platform that puts almost the entire 275-cascade system in frame at once, with rainbows arcing through the spray on sunny days. It's a quicker visit than the Argentine park, making it easy to combine with a stay in nearby Foz do Iguaçu, which also has its own bird park right next to the falls entrance.

The panoramic view from the Brazilian side was jaw-dropping — you really get a sense of the scale of the whole falls system in one go.
Rafael M. · August 2023
★★★★★
Combined Parque das Aves with the falls viewpoint in one day and both were excellent — the toucans up close at the bird park were a highlight.
Jessica L. · February 2024
★★★★☆
Quicker visit than I expected but no less impressive — the spray and rainbows from the main platform made for great photos.
