Iguaçu Falls: Brazil or Argentina Side? How to See Both (2026 Guide)
How to plan Iguaçu Falls from Foz do Iguaçu: what each side offers, how many days you need, crossing the border to Argentina, the boat ride and where to stay.
Iguaçu is a horseshoe of around 275 waterfalls on the border between Brazil and Argentina, spread over almost three kilometres. Standing next to it is one of those moments that make the whole trip worth it. The good news: it's easy to visit. The base is the Brazilian city of Foz do Iguaçu, which has an airport (IGU) with direct flights from Rio and São Paulo.

Brazil side or Argentina side?
Both. They show you different things, and the border crossing is simple.
| Brazil side | Argentina side | |
|---|---|---|
| What you get | The panorama: the whole curtain of falls in front of you | Up close: walkways over and under the falls |
| Time needed | 3 to 4 hours | A full day |
| Walking | About 1.2 km on one paved trail | Several trails, around 7 to 8 km if you do them all |
| Highlight | The walkway to the base of the Devil's Throat | The Devil's Throat balcony, right above the biggest fall |
If you only have time for one, most people prefer the Argentine side for the experience. The Brazilian side is shorter and gives the best photos. With two days, do one side each day.
How many days?
- Day 1: the Brazilian side in the morning, Parque das Aves (the bird park opposite the entrance) in the afternoon.
- Day 2: the Argentine side, all day. Leave early.
- Day 3 (optional): the Itaipu dam, one of the largest hydroelectric plants in the world, or the Three Borders landmark at sunset.
The Brazilian side
Buy your ticket online on the official park site to skip the queue. From the visitor center a park bus takes you to the start of the trail, which follows the canyon with better views at every turn. It ends at a walkway that goes out over the river in front of the Devil's Throat. You will get wet. Bring a cheap poncho or accept it.
The Macuco Safari boat ride leaves from inside the Brazilian park and takes you right under the falls. It's expensive and you'll be soaked to the bone, but people rarely regret it. Put your phone in a waterproof bag.
The Argentine side
A small train inside the park takes you to the Devil's Throat (Garganta del Diablo), a long walkway across the upper river that ends right at the edge of the biggest fall. Then do the Upper Circuit (views from above) and the Lower Circuit (views from below). Arrive when it opens to beat the crowds and the heat.
Argentina uses pesos and the exchange situation changes often. Check the park's current payment options before you go, and carry a card that works abroad without fees, like the ones we recommend.
When to go
Iguaçu is worth it all year. The water volume depends on rain upstream, not on the season you see on the calendar. Summer (December to March) brings more water and more heat, humidity and crowds. March to May and August to October are the most comfortable months. Avoid Brazilian and Argentine school holidays (July, and late December to February) if you can.
Where to stay
- Foz do Iguaçu, Brazil: the most hotels and the airport. The area along the road to the park (Avenida das Cataratas) is convenient.
- Inside the Brazilian park: one historic hotel sits right by the falls, so you can walk the trail before and after the park opens. Expensive, but special.
- Puerto Iguazú, Argentina: a small, walkable town if you'd rather base yourself on the Argentine side.
Getting there
Fly to Foz do Iguaçu (IGU) from Rio, São Paulo or other big cities. The flight from São Paulo takes about 1h40, from Rio a little over two hours. The airport is on the road to the falls, about 15 minutes from the park entrance. Buses from São Paulo take around 15 hours, so flying is worth it.
Practical tips
- Don't feed the coatis. They look cute, steal food and bite.
- Wear shoes that can get wet, and bring sunscreen and water.
- The parks close in the late afternoon, so start early.
- Combine Iguaçu with Rio or São Paulo; see our 10-day Brazil itinerary.
FAQ
Do I need a visa to visit the Argentine side?
Most Western passports don't need a visa for Argentina, but check the rules for your nationality before you go. You always need your passport, even for a day trip.
Can I see both sides in one day?
It's possible with a tour, but rushed. Two days is much better.
Is Foz do Iguaçu safe?
The tourist areas and the parks are safe. Use the usual city habits at night and take Uber or taxis after dark.
