Quick answer
Puerto Iguazú is the Argentine city next to Iguazú Falls. Brazilians only need their RG (identity card) or passport — the CNH (driver's license) is not accepted. The currency is the Argentine peso, and the exchange rate usually favors the real. The most practical transportation is a taxi or private transfer (there's no reliable Uber). The Argentine side of the Falls is more complete than the Brazilian side, with more trails and boardwalks over the cascades.
Required documents for Brazilians
Brazil and Argentina are both part of Mercosur, which makes entry easier for Brazilian citizens. Here's what you need to bring:
RG (Identity Card)
The most commonly used document. It must be in good condition with a photo that allows identification. Very old or damaged RGs may be rejected at the border. It doesn't need to be recent, but it must be legible.
Passport
Also accepted and valid. If you already have a passport, you can use it without any issues. It is not mandatory — the RG is sufficient.
Driver's license (CNH) is NOT valid
The Brazilian driver's license (CNH) is not accepted as an international travel document, even the new version with QR code. Always bring your RG or passport.
Minors: Children and teenagers traveling without one of their parents need a notarized travel authorization. If traveling with both parents, the child's identity document is sufficient.
Currency and exchange: Argentine peso (ARS)
Argentina uses the Argentine peso (ARS). The exchange rate between real and peso usually favors Brazilians. Here's how to organize your money:
Currency exchange offices (casas de cambio)
The best option for exchanging reais for pesos. There are several in downtown Puerto Iguazú, especially on Avenida Victoria Aguirre. Compare rates before exchanging — the difference between offices can be significant.
Credit and debit cards
International cards (Visa, Mastercard) are accepted at most restaurants, hotels, and larger stores. Be aware of the IOF tax (6.38% for credit) and the exchange rate applied by your bank. Cards with a dollar-denominated account can be advantageous.
US dollars
If you have dollars, they are easily exchanged at currency offices and usually get the best rate. Many tourist services also accept direct payment in dollars.
Tip: Many shops in Puerto Iguazú accept reais, but the exchange rate tends to be unfavorable. It always pays to exchange at a currency office before shopping.
How to cross the Brazil-Argentina border
The crossing between Foz do Iguaçu and Puerto Iguazú is made via the Tancredo Neves International Bridge, over the Iguazú River. The process is simple but requires stopping at both immigration checkpoints:
1. Exit from Brazil
Stop at the Brazilian Federal Revenue / Federal Police checkpoint. Present your RG or passport. An exit stamp is placed (or registered electronically).
2. Entry into Argentina
Stop at the Argentine National Immigration Office. Another document check. You receive an entry stamp valid for 90 days.
3. Estimated time
On normal days, the entire process takes 30 to 60 minutes. On extended holidays and during high season (July, January), it can take longer.
4. With a private transfer
The driver knows the procedure, stops at the correct points, and handles the process efficiently. You don't need to worry about anything.
Important: Don't skip immigration control. Some tourists cross without getting their stamp and later have problems leaving the country. With a private transfer, the driver ensures you make all the necessary stops.
Transportation in Puerto Iguazú
Puerto Iguazú is a small city (about 85,000 inhabitants), and transportation options are different from what you may be used to in Brazil:
Private transfer (the best option)
You arrange everything via WhatsApp before arriving. The driver picks you up at the airport, hotel, or border at a set time. Fixed fare, no surprises. Ideal for families, groups, and anyone who values convenience. Available 24/7, including early morning hours.
Taxi and remis
Taxis are available at the airport and at stands downtown. A remis is a private car with a driver that works by reservation (similar to a ride-hailing service, but by phone/WhatsApp). Both are safe and regulated.
Uber and ride-hailing apps
Uber has been available in Puerto Iguazú since 2023, but driver availability is very limited. It's common to open the app and not find a car. It's not reliable as a primary option. In Foz do Iguaçu (Brazilian side), Uber and 99 work normally.
Public bus (colectivo)
The Río Uruguay company operates the line from downtown Puerto Iguazú to the National Park. It runs every 20 minutes from 6:00 AM to 11:00 PM. The most affordable option, but the last bus back from the Falls departs at 6:30 PM.
What to do in Puerto Iguazú
Puerto Iguazú has much more to offer beyond the Falls. Here are the main attractions:
Iguazú Falls — Argentine side
The Argentine side is considered more complete than the Brazilian side. There are over 2 km of boardwalks that take you to Devil's Throat from above. You're just meters from the cascades. Plan at least 4-5 hours for the full visit (Upper Circuit, Lower Circuit, and Devil's Throat).
Hito Tres Fronteras
The landmark marking the triple border between Argentina, Brazil, and Paraguay. Located in downtown Puerto Iguazú, with views of the Iguazú and Paraná rivers. Beautiful for photos, especially at sunset. Free admission.
Güirá Oga (wildlife refuge)
A rescue and rehabilitation center for native wildlife from the Misiones jungle. Toucans, jaguars, caimans, and other species. Guided tour of approximately 1 hour through the jungle. Excellent for families with children.
La Aripuca
A theme park with giant structures made from recycled tree trunks. Showcases the culture and nature of the region. Interactive activities and craft shop. Located just minutes from downtown.
Local gastronomy
Puerto Iguazú has excellent restaurants with regional dishes: surubí (river fish), empanadas, asado (Argentine barbecue), and dulce de leche desserts. Avenida Córdoba and the area around La Feirinha have the best options.

Safety and practical tips
Puerto Iguazú is a quiet, tourist-friendly city, but it's worth following some recommendations:
Keep documents safe
Carry digital copies (phone photos) of your RG and passport. Leave the originals in the hotel safe when you don't need them.
Watch out for the sun
The region is very hot, especially in summer (December to March). Use sunscreen, wear a hat, and bring water on the Falls trails.
Wild animals
In the National Park, coatis are friendly-looking but can be aggressive if you have food. Do not feed the animals.
Drinking water
Tap water in Puerto Iguazú is drinkable, but if you prefer, bottled water is sold everywhere.
