Iguazu Falls Border Crossing and Visa Requirements

Visiting Iguazú Falls is special because you can experience it from two countries – Argentina and Brazil. 

If you plan to explore both sides of the falls, it’s essential to understand the border crossing procedures and visa requirements for each country. 

The border crossing may sound tricky, but don’t worry — it’s very straightforward once you know the process. 

This guide covers border crossing between Argentina and Brazil, including visa, necessary travel tips, and everything you need for a smooth visit.

Choose between the Argentina side or Brazil side tours, or experience both in a full-day tour. For an extra thrill, add a Macuco Safari or Gran Aventura boat ride, or take a helicopter tour for breathtaking aerial views.

Iguazú Falls border crossing between Argentina and Brazil

To cross between Argentina (Puerto Iguazú) and Brazil (Foz do Iguaçu), you need:

• A valid passport (make sure it’s not expiring soon).
• Visa (if required) – check your nationality, as some countries need a visa for Brazil, Argentina, or both.
• Entry stamp – immigration officers on both sides usually stamp your passport.
  

Tip: Day tours arrange a quick border crossing with a group list, so you may not need to show your passport at the checkpoint. But always carry your passport, just in case.

Visa requirements for Argentina and Brazil

Before visiting Iguazu Falls, it’s important to understand the visa requirements for both Argentina and Brazil, as they vary depending on your nationality and travel plans.

From April 10, 2025, citizens of the United States, Canada, and Australia will need a visa to enter Brazil, even for short tourist stays. Brazil offers an electronic visa (eVisa), which allows stays of up to 90 days with multiple entries.

You can apply online at brazil.vfsevisa.com, submitting your passport, photo, and travel documents.

Approval usually takes about five business days, so it’s recommended to apply at least two weeks before your trip. If you plan to cross into Brazil and return to Argentina, ensure your visa allows multiple entries.

Travelers from the EU and many other countries remain visa-exempt for both Argentina and Brazil, but requirements differ by nationality—so always confirm with your local consulate before traveling.

• Transportation: Public buses, taxis, private vehicles, and guided tours are available for crossing.

• Operating hours: The border is open 24/7; however, services may be limited during late-night hours. 
• Stamps: Always keep your entry/exit stamps – you may face problems later if you miss one.
• Local currency: While both countries accept major credit cards, it’s advisable to have some local currency (Argentine Pesos and Brazilian Reais) for small purchases.
