The Biggest Mistakes First-Time Visitors Make in Argentina
The most common mistake is booking a same-day domestic connection out of Buenos Aires without accounting for the hour-plus transfer between the international airport (Ezeiza/EZE) and the domestic one (Aeroparque/AEP). Others: bringing cash expecting a 2023-style 'blue dollar' windfall (mostly gone since 2025), falling for the counterfeit-bill-swap or fake-police scams, self-driving Mendoza's wineries, and assuming Patagonia's trails are open in July because it's 'summer' back home. None of these ruin a trip, but all of them are avoidable with five minutes of planning.
Every destination has a list of rookie mistakes, but Argentina's are unusually specific and unusually avoidable — most come down to one wrong assumption (about an airport, an exchange rate, or a season) rather than genuine bad luck. Here's what actually trips people up.
1. Booking a same-day domestic flight straight off an international arrival
International flights land at Ezeiza (EZE); nearly all domestic flights to Patagonia, Mendoza, or Iguazu depart from Aeroparque (AEP), a separate airport about 20 miles across the city with no shared terminal. Clearing immigration, collecting bags, and crossing the city by road takes an hour in light traffic, 90 minutes or more at rush hour, before you even check in again. Build in at least 4–5 hours between an international arrival and a domestic departure.
2. Bringing a stack of cash for the 'blue dollar' rate
Plenty of pre-2025 articles still circulating online describe a huge arbitrage between Argentina's official exchange rate and the informal 'blue dollar' cash rate — advice that's now largely outdated. Since Argentina lifted its currency controls in April 2025, the gap has narrowed to just a few percent, and cards now work at broadly fair rates. Bring some USD or EUR as a practical backup, not as a strategy.
3. Falling for the counterfeit-bill handback trick
A common taxi and street-vendor scam: you hand over a large peso bill, the person claims it's counterfeit or that they lack change, and swaps it for an actual counterfeit before handing it back. Pay with smaller bills where possible, and if you do hand over a large note, watch it the whole time and know that real bills have a woven-in (not glued-on or printed) security thread you can check against the light.
4. Falling for the fake plainclothes police scam
Someone claiming to be a plainclothes officer conducting an anti-counterfeiting check approaches you on a busy street and asks to inspect your wallet or cash — then pockets bills or swaps in counterfeits before handing it back. Real Argentine police don't conduct spontaneous cash inspections of tourists on the street; politely decline, ask to see identification, and if in doubt, insist on walking to the nearest police station or tourist-police post together rather than handing anything over on the spot.
5. The mustard or 'bird poop' distraction trick
You're sprayed with mustard, mayonnaise, or a similar substance that looks like bird droppings, and a helpful-seeming stranger offers to help you clean up — while an accomplice goes through your bag. If it happens, don't stop to clean up on the spot or follow anyone anywhere; keep moving to a safe, populated spot first.
| Mistake | The fix |
|---|---|
| Same-day EZE-to-AEP domestic connection | Leave 4–5+ hours between an international arrival and any domestic departure |
| Bringing cash for a 'blue dollar' windfall | Use a no-foreign-fee card; carry $200–400 cash as backup, not a strategy |
| Handing over large bills to taxis or vendors | Pay with smaller denominations; check any large bill's security thread against the light |
| Engaging with unsolicited 'police' cash checks | Decline politely, ask for ID, insist on a real police post if pressured |
| Self-driving between Mendoza wineries after tastings | Hire a driver, join a tour, or rent a bike in Maipú instead |
6. Self-driving between Mendoza's wineries after tastings
It happens constantly and it's genuinely dangerous on unfamiliar roads — hire a private driver for the day (affordable, especially split among a group), join an organized wine-tour van, or rent a bike in Maipú, where several wineries sit close enough together for a slow, careful cycling day.
7. Assuming Patagonia is fully open because it's 'summer' back home
Argentina's seasons are flipped — June, July, and August are the Southern Hemisphere winter, and some El Calafate and El Chaltén hotels and tour operators scale back or close entirely during that window. If you want Patagonia's trekking season, plan for November through March instead.
8. Not booking the Fitz Roy trail permit ahead
Since October 2024, El Chaltén's popular Laguna de los Tres trail to Fitz Roy requires a paid entry permit booked online in advance — local guides can't buy it for you on the spot. Booking it last-minute in peak season (December–February) risks finding it sold out.
None of these mistakes are dealbreakers — they're all avoidable with a few minutes of planning before you land. The airport transfer and the outdated currency advice trip up more first-timers than any actual crime does; Argentina is genuinely one of the safer countries in South America for visitors who take normal city precautions.
