When you start looking at flights to Iguazu Falls, one thing can be confusing: there are two airports, in two different countries. IGR is on the Argentine side, and IGU is on the Brazilian side.
The best choice depends less on which airport is closest and more on your full itinerary: where you’re coming from, where you’re going next, how many days you have, and which side of the falls you plan to visit.
If you’re coming from Buenos Aires, IGR is usually the natural choice. If you’re coming from Rio de Janeiro or São Paulo, IGU usually makes more sense. And if you’re traveling from Argentina through Iguazu and continuing into Brazil, flying into one airport and out of the other can be a very practical option.
The simple rule: don’t choose the airport first. Choose it around the rest of your trip.
Quick answer: IGR or IGU?
Flying from Buenos Aires? IGR is usually the most practical choice.
Flying from Rio de Janeiro or São Paulo? IGU usually makes more sense.
Traveling Buenos Aires → Iguazu → Rio? Consider flying into IGR and out of IGU.
Traveling Rio → Iguazu → Buenos Aires? Consider flying into IGU and out of IGR.
Visiting both sides? Choose the airport around the flights before and after Iguazu, your hotel location and your available time — not simply around which side of the falls you want to see first.
IGR vs. IGU at a glance
Before looking at specific itineraries, here’s the simplest way to understand the two airports.
| Cataratas del Iguazú International Airport (IGR) | Foz do Iguaçu International Airport (IGU) | |
| Country | Argentina | Brazil |
| Serves | Puerto Iguazú | Foz do Iguaçu |
| Closest falls side | Argentine side | Brazilian side |
| Usually makes sense from | Buenos Aires or elsewhere in Argentina | Rio de Janeiro, São Paulo or elsewhere in Brazil |
| Natural first visit | Argentine side | Brazilian side |
| Often convenient when continuing toward | Argentina | Brazil |
| Arrival-day visit can work well | Argentine side, if the flight lands early enough | Brazilian side, if the flight lands early enough |
| Useful for Buenos Aires → Iguazu → Rio | Good arrival airport | Good departure airport |
| Useful for Rio → Iguazu → Buenos Aires | Good departure airport | Good arrival airport |
One important point: the closest airport is not always the best airport for your trip. Your arrival city, departure city, hotel and number of days in Iguazu should all be considered together.
Coming from Buenos Aires? IGR usually makes the most sense
If you’re flying from Buenos Aires, IGR is usually the most practical airport to choose.
It’s on the Argentine side and very close to Iguazu National Park, which can make it possible to visit the Argentine side on the same day you arrive if your flight lands early enough.
If you have another day available, you can then visit the Brazilian side the following day.
But your hotel choice should also depend on what happens after Iguazu.
If you’re continuing to Rio de Janeiro, for example, staying on the Brazilian side before your departure can make things easier. That way, you don’t have to depend on an international border crossing on the same day as your flight.
Coming from Rio or São Paulo? IGU is usually the better choice
If you’re flying from Rio de Janeiro or São Paulo, IGU is usually the most practical airport for Iguazu Falls.
You’re already traveling within Brazil, so flying directly to Foz do Iguaçu normally makes much more sense than connecting through Buenos Aires and coming back toward Iguazu from the Argentine side.
From IGU, you can visit the Brazilian side first or cross into Argentina, depending on your schedule and how many days you have.
As with IGR, the airport itself should not be the only thing you consider. Your hotel, the order of your visits and where you’re flying next all matter.
Buenos Aires → Iguazu → Rio: consider flying into IGR and out of IGU
If your trip takes you from Buenos Aires to Iguazu and then on to Rio de Janeiro, using two different airports can be a very practical option.
A simple route can look like this:
Buenos Aires → IGR → Argentine side → Brazil → IGU → Rio
Flying into IGR and leaving from IGU can save you from unnecessary backtracking and can make the whole Iguazu stop easier to organize.
The exact order still depends on how many days you have and what time your flights arrive and depart.
If your stay is short, those flight times become especially important. If you have two or more days, you usually have much more flexibility to visit both sides without rushing.
In many cases, it also makes sense to spend your final night on the Brazilian side if your next flight leaves from IGU. That way, you avoid having to cross the international border on the same day as your flight.
Choose your hotel with your departure airport in mind
One mistake I see travelers make is choosing a hotel only based on which side of the falls they want to visit.
Your departure airport matters too.
If your next flight leaves from IGU in Brazil, staying on the Brazilian side for your final night can make things easier. You avoid having to cross an international border on the same day as your flight.
The same idea works in reverse. If you’re flying out of IGR in Argentina, staying on the Argentine side before departure may be more practical.
This does not mean you always need to change hotels. It simply means your hotel, airport and itinerary should be planned together, especially if your schedule is tight.
What if your airport and hotel are on different sides of the border?
This is where airport choice becomes more than a question of distance.
Landing at IGR and staying in Puerto Iguazú is a different situation from landing at IGR and staying in Foz do Iguaçu. In the second case, your airport transfer already includes an international border crossing.
The same logic works in reverse. Landing at IGU and staying in Foz do Iguaçu keeps your arrival within Brazil, while landing at IGU and staying in Puerto Iguazú means crossing into Argentina before reaching your hotel.
This does not automatically make one option better than the other. It simply means your airport, hotel, luggage, border crossing and first planned visit should be considered as one itinerary rather than as separate bookings.
Can you visit Iguazu Falls on the day you arrive?
Often, yes.
If your flight lands in the late morning or early afternoon, you may still have enough time to visit one side of Iguazu Falls the same day.
Whether that works depends on which airport you arrive at, which side you want to visit, the park schedule, and how much time you want to spend there.
If you arrive at IGR from Buenos Aires, the Argentine side can be a practical option because the airport is close to Iguazu National Park.
If you arrive at IGU from Rio de Janeiro or São Paulo, visiting the Brazilian side the same day can also work well.
On a short stay, using your arrival day this way can save valuable time. But I would always build the plan around your actual flight time rather than assume that every midday arrival will work.
Can you visit the falls before an evening flight?
Yes, it can be done.
If your flight leaves in the late afternoon or evening, visiting one side of Iguazu Falls in the morning can be realistic.
The main thing to consider is not only the time. It’s also how active you want your last day to be.
A morning at the falls followed by a transfer straight to the airport can make good use of your time, especially on a short trip, but it can also be physically demanding.
I would only plan it when the flight time gives you a comfortable margin and the itinerary does not depend on a last-minute border crossing.
If your schedule is more relaxed, keeping the final day lighter may simply be more enjoyable.
Is it easy to fly into IGR and out of IGU?
Yes, in most cases it’s quite easy to organize.
Travelers often assume they need to use the same airport for both arrival and departure, but that isn’t always necessary at Iguazu.
You can arrive at IGR in Argentina, visit the Argentine side, cross into Brazil, and later depart from IGU. The reverse can also work.
The main things to plan are your hotel, the order of the two sides, your luggage, and enough time for the border crossing.
If those pieces are organized properly, using both airports can actually make your trip more efficient and help you avoid unnecessary backtracking.
The important part is to look at the whole itinerary before booking, not just the airport that seems most convenient at first.
What should U.S. and Canadian travelers know about crossing between Brazil and Argentina?
If you’re traveling with a U.S. or Canadian passport and plan to visit both sides of Iguazu Falls, remember that you’ll be crossing an international border.
As of this article’s latest review, U.S. and Canadian passport holders need a visa to enter Brazil for tourism, including when crossing from Argentina to visit the Brazilian side of Iguazu Falls. Since April 10, 2025, Brazil has again required visas for citizens of both countries, with an e-Visa available online. Check the latest requirements on the official Brazilian government e-Visa information page before traveling.
U.S. and Canadian citizens currently do not need a tourist visa to enter Argentina for stays of up to 90 days. U.S. travelers can verify the current rule through the Argentine Consulate in New York, and Canadian travelers through the Argentine Consulate in Montreal.
Argentina also currently requires foreign visitors to have travel insurance covering medical assistance and hospitalization. Because entry requirements can change, always verify the latest rules with the Brazilian and Argentine authorities before traveling.
The border crossing itself is a normal part of visiting both sides, but the time it takes can vary. That’s why I would avoid building a tight flight-day schedule that depends on crossing the border at the last minute.
Which airport is better if you’re visiting both sides of Iguazu Falls?
There isn’t one airport that is always better.
If you plan to visit both the Brazilian and Argentine sides, the best airport depends on the rest of your trip.
If you’re arriving from Buenos Aires, IGR may be the most natural starting point. If you’re coming from Rio de Janeiro or São Paulo, IGU will usually make more sense.
If your trip continues into the other country, using one airport for arrival and the other for departure can sometimes be the easiest option.
The most important thing is to look at your arrival flight, departure flight, hotel and number of days in Iguazu together before deciding.
Visiting both sides is usually easy to organize when those pieces are planned in the right order.
If you are still deciding how to divide your time between the two parks, see our guide to choosing between the Brazilian and Argentine sides of Iguazu Falls based on your itinerary.
Four common Iguazu flight itineraries — and what usually works best
Here are four common ways travelers include Iguazu Falls in a South America trip, and the airport combination that usually makes the most sense.
Buenos Aires → Iguazu → Buenos Aires
IGR is usually the simplest choice.
You stay within Argentina for both flights, and IGR is also very close to the Argentine side of Iguazu Falls.
If you have enough time, you can still cross into Brazil to visit the Brazilian side before returning to Argentina for your flight home.
Rio or São Paulo → Iguazu → Rio or São Paulo
IGU is usually the most practical option.
You stay within Brazil for your flights, which keeps the transportation simple.
You can visit the Brazilian side first and cross into Argentina for the Argentine side if your itinerary includes both parks.
Buenos Aires → Iguazu → Rio
This is where using both airports can work especially well.
A practical route can be:
Buenos Aires → IGR → Argentine side → Brazil → IGU → Rio
Instead of returning to Argentina just to catch another flight, you continue naturally into Brazil.
If your departure from IGU is early or your schedule is tight, spending your final night in Foz do Iguaçu can also make the departure day easier.
Rio → Iguazu → Buenos Aires
The same idea works in reverse.
A practical route can be:
Rio → IGU → Brazilian side → Argentina → IGR → Buenos Aires
In this case, finishing your stay on the Argentine side can make sense, especially if your flight from IGR leaves early or you want to avoid crossing the border on departure day.
These are useful starting points, not fixed rules. Your flight times and the number of days you have in Iguazu can completely change what works best.
That’s why I always recommend looking at the whole route before booking the airport, hotel and order of the two sides separately.
IGR and IGU airport FAQ
Are IGR and IGU the same airport?
No. They are two different airports in two different countries.
IGR is on the Argentine side, near Puerto Iguazu and the Argentine side of the falls. IGU is on the Brazilian side, in Foz do Iguaçu and close to the Brazilian side.
The airport codes look similar, so it’s worth double-checking them before booking your flights.
Can I fly into IGR and fly out of IGU?
Yes. In many itineraries, this can actually be more practical than returning to the same airport.
It works especially well if you’re traveling through South America in one direction — for example, Buenos Aires → Iguazu → Rio de Janeiro.
The key is to plan your hotel, visits and border crossing around your arrival and departure times.
Which airport is closer to Iguazu Falls?
Both airports are well located for visiting the falls, but each one is naturally more convenient for its own side.
IGR is closer to the Argentine side, while IGU is closer to the Brazilian side.
But distance alone should not decide your airport. Your flights before and after Iguazu are usually more important.
Do I need to cross the border if I use both airports?
Yes. If you arrive through IGR and leave through IGU, or the other way around, you will cross the Brazil–Argentina border during your stay.
This is easy to include in a well-planned itinerary, but I would avoid leaving the border crossing until the last minute before an important flight.
Can a private transfer be arranged between the two sides?
Yes. Private transportation can be arranged between airports, hotels and the Brazilian and Argentine sides of Iguazu Falls.
This can be especially useful when your itinerary involves different arrival and departure airports, luggage, or a tight schedule.
So, should you choose IGR or IGU?
There is no single airport that is best for every Iguazu Falls trip.
Coming from Buenos Aires? IGR will often make the most sense.
Coming from Rio de Janeiro or São Paulo? IGU will usually be the easier choice.
Coming from Argentina and continuing into Brazil — or the other way around? Using both airports may be the smartest option.
The most important thing is to plan your arrival airport, departure airport, hotel, number of days and order of visits together.
That simple approach can save unnecessary backtracking, reduce stress around the border and help you make better use of your time at Iguazu Falls.
