Airports and Gateway Cities for Iguazu Falls
- Ramiro Rodriguez
Iguazu Falls is one of the most amazing places on earth and a must-see when visiting South America. So, how to access Iguazu Falls?
Where are Iguazu Falls?
Argentina and Brazil share Iguazu Falls. So, you can visit the falls from both sides. You can arrive from Rio de Janeiro or Sao Paulo with daily flights to Foz do Iguaçu and from there visit the national parks. From Argentina, you can fly to Puerto Iguazu and visit both parks from there.
Quick Answer: Should You Fly to IGR or IGU?
Choose IGR Airport in Argentina if you are arriving through Buenos Aires, staying in Puerto Iguazú or beginning your trip with the Argentine side of the falls.
Choose IGU Airport in Brazil if you are arriving through São Paulo, Rio de Janeiro or another Brazilian city, staying in Foz do Iguaçu or beginning with the Brazilian side.
Both airports can be used regardless of where your hotel is located. However, choosing an airport in a different country from your accommodation requires an international border crossing, additional transfer time and the correct entry documents.
Always check the three-letter airport code before purchasing your flight:
- IGR: Cataratas del Iguazú International Airport, Argentina
- IGU: Foz do Iguaçu International Airport, Brazil
- AGT: Guaraní International Airport, Paraguay — a less convenient option for most visitors to the falls

Main Flight Routes to Iguazu Falls
Flights to IGR Airport in Argentina
Most visitors using IGR arrive on a domestic flight from Buenos Aires. Depending on the season and airline schedules, services may also be available from other Argentine cities such as Córdoba, Mendoza, Salta or Bariloche.
A nonstop flight from Buenos Aires to IGR normally takes approximately 1 hour 50 minutes to 2 hours.
Buenos Aires has two principal airports:
- AEP – Aeroparque Jorge Newbery
- EZE – Ministro Pistarini International Airport
International passengers should verify whether their connection to Iguazu departs from the same Buenos Aires airport. Transferring between EZE and AEP requires a road journey across the city and considerably more connection time.

Flights to IGU Airport in Brazil
IGU is principally connected with major Brazilian aviation hubs. Common routes include services from São Paulo, Rio de Janeiro and Curitiba, with other connections depending on the season and current airline schedules.
Typical nonstop flight times are approximately:
| Route | Approximate flight time |
|---|---|
| Buenos Aires–IGR | 1 hour 50 minutes–2 hours |
| São Paulo–IGU | 1 hour 35 minutes–1 hour 50 minutes |
| Rio de Janeiro–IGU | Approximately 2 hours |
| Curitiba–IGU | Approximately 1 hour 10 minutes |
Flight routes and frequencies can change. Travelers should confirm the operating airport, airline schedule and baggage conditions before booking.
Which Airport Should You Choose According to Your Hotel?
If Your Hotel Is in Puerto Iguazú
IGR is normally the best choice. You remain within Argentina and do not need to cross an international border after landing.
Arriving at IGU is still possible, but your transfer must leave Brazil, complete the relevant border procedures and continue to Puerto Iguazú. Allow approximately 45–75 minutes, and more during busy periods.
If Your Hotel Is in Foz do Iguaçu
IGU is generally the most convenient airport. Transfers to central hotels normally take around 15–25 minutes and involve no border formalities.
If you arrive at IGR, your driver must take you through Argentine and Brazilian immigration before continuing to Foz do Iguaçu. The complete journey may take approximately 45–75 minutes or longer, depending on the border.
If You Are Staying at Gran Meliá Iguazú
IGR is the natural choice because the hotel is located inside Iguazú National Park on the Argentine side. The transfer does not require a border crossing.
Visitors arriving at IGU can reach the hotel, but they must first enter Argentina and then continue to the national park.
If You Are Staying at Hotel das Cataratas
IGU is the most convenient airport because the hotel is located inside Iguaçu National Park on the Brazilian side, very close to the airport.
Passengers arriving at IGR must cross from Argentina into Brazil before reaching the hotel.
If You Plan to Visit Both Countries
You do not need to change hotels or use both airports. Choose the airport that best matches:
- Your international or domestic flight itinerary.
- The country where your hotel is located.
- Your next destination after Iguazu.
- The total cost of the flight plus cross-border transfers.
For example, a less expensive flight to IGU may not represent a real saving if your hotel, first excursion and departure flight are all in Argentina.

Airport and Hotel Transfer Times
| Transfer | Normal planning estimate |
|---|---|
| IGR to Puerto Iguazú hotels | 20–30 minutes |
| IGR to Argentine National Park | 15–20 minutes |
| IGU to central Foz do Iguaçu | 15–25 minutes |
| IGU to Brazilian National Park | 5–10 minutes |
| IGR to Foz do Iguaçu hotels | 45–75 minutes, including border procedures |
| IGU to Puerto Iguazú hotels | 40–70 minutes, including border procedures |
| Puerto Iguazú to Foz do Iguaçu | 30–60 minutes or longer |
| IGR to IGU | Approximately 45–90 minutes or longer |
These are practical estimates, not guaranteed journey times. Border congestion can increase significantly during weekends, public holidays, school vacations and peak travel periods.
Crossing the Argentina–Brazil Border
Travel between Puerto Iguazú and Foz do Iguaçu is an international journey, even when the two cities appear very close on the map.
Travelers should:
- Carry their original passport or another document legally accepted for their nationality.
- Check visa or electronic authorization requirements for both Argentina and Brazil.
- Complete all required entry and exit procedures.
- Verify special documentation requirements when travelling with minors.
- Keep hotel reservations and onward-flight information accessible.
- Confirm that a rental car is authorized and insured for international travel.
- Allow additional time before flights, fixed tours or other non-refundable services.
A visit of only a few hours to the other side of the falls still counts as entering another country. National park admission does not replace immigration permission.
For the smoothest journey, reserve a private transfer or an organized excursion whose operator is experienced with international border procedures.
Can You Arrive at One Airport and Depart From the Other?
Yes. An open-jaw itinerary—arriving at IGR and departing from IGU, or the reverse—can be useful when continuing through a different country.
For example:
- Buenos Aires → IGR → Iguazu Falls → IGU → Rio de Janeiro
- São Paulo → IGU → Iguazu Falls → IGR → Buenos Aires
This arrangement can reduce backtracking, but it requires an international land transfer during the stay. Check immigration requirements before purchasing the flights and avoid scheduling the border crossing too close to departure.
What About Ciudad del Este and AGT Airport?
Guaraní International Airport, code AGT, serves the Paraguayan side of the Triple Frontier. It is generally less convenient for travelers whose principal purpose is visiting Iguazu Falls.
The waterfalls are not located in Paraguay. Visitors arriving through AGT must travel to Ciudad del Este and then enter Brazil or Argentina before reaching either national park. This option is most practical for travelers already visiting Paraguay or following a regional itinerary.
Final Recommendation
For most travelers, the simplest rule is:
- Buenos Aires or an Argentine itinerary: fly to IGR.
- São Paulo, Rio de Janeiro or a Brazilian itinerary: fly to IGU.
- Hotel in Puerto Iguazú: prefer IGR.
- Hotel in Foz do Iguaçu: prefer IGU.
- Hotel inside one of the national parks: use the airport on the same side whenever possible.
If the airfare difference is substantial, compare the complete journey rather than the ticket price alone. Include cross-border transportation, immigration time, visa requirements and the location of your first and last activities.
