You’ll need a valid passport to cross between Argentina and Brazil. Even if you're only visiting for a few hours, both countries have immigration controls, and your passport will be checked each time.

Visa requirements vary depending on your nationality:

• Mandated on April 10, 2025, the US, Canadian, and Australian citizens will need a visa to enter Brazil, even for short tourist stays. Brazil offers an electronic visa (eVisa) that allows stays up to 90 days and multiple entries. Apply online at brazil.vfsevisa.com and submit your passport, photo, and travel documents. Approval usually takes 5 business days, so apply at least two weeks before your trip.
  
• If you're crossing into Brazil and planning to return to Argentina, make sure your Brazilian visa allows multiple entries.

By Taxi (Fastest & easiest)

• The quickest way to cross the border. Expect a 45-minute ride, including immigration stops. Taxis are widely available on both sides, and most drivers are used to tourists doing the crossing. Negotiate a round-trip fare if you're planning to come back the same day.
  
• Cost: Expect to pay around $15-$25 USD for the ride (one way).

By Bus (Cheapest, but slower)

• Buses run frequently between Puerto Iguazú (Argentina) and Foz do Iguaçu (Brazil). Expect a 1.5-hour journey because the bus stops at immigration, and everyone needs to get off for passport control. The most popular company is Rio Uruguay departing every 20-30 minutes.
  
• Cost: Around $2-$3 USD per ride. Super cheap, but not the most time-efficient option.

By Rental Car (Requires paperwork)

• If you’ve rented a car, you need to tell the rental company you’re crossing the border. Expect additional insurance fees and paperwork. Immigration checks will take longer since they verify car documents too.

Border control can be busy

• Weekends and holidays = longer wait times. If you can, avoid crossing between 10am - 2pm when most tourists make the trip.
  
• Brazil’s immigration rate is usually faster than that of Argentina. Argentina tends to check bags more often, so be patient.

Changing currency

• Argentina uses Argentine Pesos (ARS), Brazil uses Brazilian Real (BRL).
  
• Don’t stress too much about exchanging money—most places near the falls accept USD, credit cards, or both currencies.

Wi-Fi & SIM cards won’t always work

• Argentina and Brazil have different mobile networks. If you're using a local SIM, expect to lose service when you cross.
  
• Wi-Fi is available at bus terminals, some taxis, and both national parks. If you rely on Uber in Brazil, make sure to request it before you leave WiFi zones.

Uber vs. Taxis

• Brazil has Uber. It’s cheaper and more reliable than taxis.
  
• Argentina doesn’t have Uber, only taxis. (Some drivers accept payment in USD, but ask before hopping in.)
  
• Uber cannot take you across the border. If you’re relying on it, take an Uber to the border, cross on foot, then request another on the other side.

Local buses

• Cheap but can be slow. If you're heading to the falls, get on a direct bus to the National Park entrance instead of stopping in town first.
  
• Buses between Puerto Iguazú (Argentina) and Foz do Iguaçu (Brazil) run frequently, but crossing can take time.

How to get around?

Argentina has a free ecological train (Jungle Train) that runs every 30 minutes and stops at:

Central Station (Park Entrance)

1. Cataratas Station (For Upper & Lower Circuits)
   
2. Devil’s Throat Station (For the most iconic viewpoint)
   How much time do you need?

A full day—no less. If you’re someone who likes to take it slow, maybe even two days.

Pro Tips:
✔ Go to Devil’s Throat first → It gets crowded fast. The earlier, the better.
✔ Bring cash → Argentina has crazy inflation, and credit card machines sometimes don’t work.

What’s it like?

Brazil gives you the panoramic postcard view of Iguazu. While Argentina takes you into the falls, Brazil lets you see the entire spectacle at once. The Brazilian side is shorter and simpler—one main trail that ends with a jaw-dropping, mist-soaked walkway right over Devil’s Throat.

Key trail & attractions:

• Main Walkway (Trilha das Cataratas) → A 1.5 km path along the edge of the river, with multiple viewpoints. Starts with distant panoramic views and ends right in front of Devil’s Throat.
  
• Devil’s Throat Walkway → A raised bridge over the Iguazu River, right on the edge of the abyss. This is where you get completely drenched, but the view? Insane.

Elevator to Upper Lookout → After the walkway, take the glass elevator to an upper platform, giving you a higher perspective of the falls.

The Argentina side is larger, more physical, and more immersive. You walk long distances, spend hours on elevated walkways, and slowly build up to Devil’s Throat. Starting here makes sense when your energy is high and you want to explore without feeling rushed. By the end of the day, you will be tired, but you will have seen the falls from every possible angle.

This order works best if you have one and a half to two days in Iguazú.

The Brazil side is quicker and more efficient. The main trail delivers panoramic views almost immediately, and the entire visit can be done in a few hours. If you are arriving late, traveling the same day, or only have half a day available, starting with Brazil ensures you still get the most iconic views without exhaustion.

This is also a good option if you prefer minimal walking.
