Brazil travel · Foz do Iguaçu
Do both if you can. The Brazilian side shows you the whole falls system from across the canyon in a few hours. The Argentine side puts you on catwalks right over the water and takes most of a day. Only one day? Most first-timers are happier on the Argentine side.

| 🇧🇷 Brazilian side | 🇦🇷 Argentine side | |
|---|---|---|
| What you see | The panorama: the whole falls system from across the canyon | The falls from above and up close, on catwalks over the water |
| Time needed | A few hours to half a day | Most of a day |
| Highlight | The walkway over the river at the end of the trail, in the spray, facing the Devil's Throat | The Devil's Throat (Garganta del Diablo) seen from directly above |
| Walking | One main trail, easy to do in a morning | Several trails; plan on walking a good part of the day |
| Border | No border crossing if you stay in Foz do Iguaçu | International border: physical passport, check the entry rules first |
Go to the Argentine side and start early. You will be inside the falls, not just looking at them, and that is what most people remember. If you cannot cross the border, the Brazilian side is still unforgettable, and it fits in a morning.
Give each side its own day, and do not try to squeeze a third big activity into the same two days. With a third day, go slower: the bird park, the Itaipu dam and the sunset where Brazil, Argentina and Paraguay meet. That is exactly the shape of my free 3-day Iguazu plan.
Carry your physical passport. Entry rules for Argentina depend on your nationality and are not the same rule as Brazil's, which trips people up often. Check them on official government sources a few weeks before you travel, and again just before.
Most travellers stay on the Brazilian side, in Foz do Iguaçu. Near the national park entrance, the morning ride to the falls is short; the city centre has more restaurants and is still a short drive from both sides. More in the Foz do Iguaçu guide.
Neither is better: they are different. The Brazilian side gives you the panoramic view of the whole falls in a few hours. The Argentine side puts you on catwalks right over the water and takes most of a day. If you only have one day, most first-timers are happier on the Argentine side.
It is possible with a very early start, but you will rush the Argentine side, which deserves a full day. Two days, one per side, is the honest answer.
Yes. You cross an international border, so carry your physical passport. Entry rules for Argentina depend on your nationality and are not the same as Brazil's: check them on official government sources before you go.
On the Brazilian side, in Foz do Iguaçu: near the national park entrance for the shortest morning ride to the falls, or in the city centre for more restaurants, still a short drive from both sides.
Opening hours, tickets and border rules change: always confirm on the official sites of the national parks and of each country's government before you go.
