Full guide to Ruta 40 (Patagonia Section) β†’

Embarking on a Ruta 40 adventure through Patagonia is an unforgettable experience, but understanding Argentina's financial system is crucial for a stress-free trip. The country operates with a dual exchange rate system: the official rate and the 'DΓ³lar Blue' (blue dollar) or parallel market rate, which typically offers a significantly more favorable exchange for foreign currencies. This guide will equip you with the knowledge to manage your money effectively, ensuring you're ready for everything from fuel stops in remote areas to delightful meals in charming Patagonian towns. Cash remains king, especially off the beaten path.

Exchange Rate

Argentina operates with both an official exchange rate and a 'DΓ³lar Blue' (blue dollar) or parallel market rate. For tourists exchanging foreign cash (primarily USD), the blue dollar rate offers a significantly more favorable exchange, often double or more than the official bank rate. While technically an informal market, it is widely accepted and utilized by tourists. For debit/credit card purchases, a special 'MEP dollar' rate is often applied automatically, providing a rate much closer to the blue dollar than the official rate. Always check current rates before your trip, as they can fluctuate significantly.

Exchange Options

Bank ATM

Pros: Convenient for small, urgent cash needs in larger towns. Official exchange rate is applied.
Cons: Very low withdrawal limits (often equivalent to $50-100 USD per transaction), high transaction fees for foreign cards, and ATMS frequently run out of cash, especially on weekends or holidays. The official rate is very unfavorable.
Recommended For: Emergency cash only when other options are unavailable, or for topping up small amounts of pesos.

Western Union

Pros: Offers the best official way to access a rate very close to the 'blue dollar' rate. You can send money to yourself from your home country and pick up pesos in Argentina. Widely available in most towns, including many along Ruta 40.
Cons: Can involve long queues, especially at peak times. Funds might not be immediately available in smaller branches. Requires planning ahead to send money.
Recommended For: The primary recommended method for exchanging larger sums of money due to the highly favorable exchange rate.

Exchanging USD cash (Blue Dollar Market)

Pros: Offers a highly favorable 'blue dollar' rate for USD cash. Can be found in major cities (e.g., Bariloche, El Calafate) through 'cuevas' (unofficial exchange houses) or trusted individuals.
Cons: Can be risky if you're unfamiliar with the process or dealing with untrustworthy individuals. Security concerns with carrying large amounts of cash. Not always available in very small or remote towns along Ruta 40.
Recommended For: Tourists confident in navigating the informal market, typically through referrals, for the best cash rates. Always count your money carefully and ensure security.

Credit/Debit Card Purchases

Pros: Convenient for larger purchases in established businesses (hotels, larger restaurants, supermarkets). Many transactions will automatically apply a favorable 'MEP dollar' rate, close to the blue dollar, reducing the need for cash exchange.
Cons: Not universally accepted, especially in smaller shops, roadside eateries, or for fuel in remote areas. Subject to international transaction fees from your home bank. Some smaller businesses may surcharge for card payments or prefer cash.
Recommended For: Paying for accommodations, major restaurant bills, and supermarket purchases in urban centers, provided the favorable MEP rate is applied.

ATM Information

ATMs along Ruta 40, especially in the Patagonian section, are notoriously unreliable. They are scarce in smaller towns and often run out of cash, particularly on weekends or holidays. Withdrawal limits are very low, typically equivalent to $50-100 USD per transaction, and foreign transaction fees from both your home bank and the Argentine ATM operator can be substantial. Do not rely solely on ATMs for your cash needs; always plan to arrive with sufficient pesos obtained via Western Union or USD cash exchange.

Card Acceptance

While major credit cards (Visa, Mastercard) are accepted in hotels, larger restaurants, and supermarkets in bigger towns (e.g., Bariloche, El Calafate, Esquel), cash is absolutely essential for many aspects of a Ruta 40 road trip. Smaller shops, local eateries, gas stations in remote areas, and many tour operators will only accept cash. Always ask 'Aceptan tarjeta?' (Do you accept card?) before ordering or purchasing. Be aware that some businesses might add a surcharge for card payments or offer a better price for cash.

Tipping Guide

Tipping ('propina') is customary in Argentina: - Restaurants: Around 10% is standard for good service. Leave cash directly, as it's not usually added to card payments. - Taxis: Not expected, but you can round up the fare for good service. - Tour Guides: 10-20% of the tour cost, depending on satisfaction, especially for multi-day excursions. - Gas Station Attendants ('ν”Œλ ˆμ΄λ³΄μŠ€'): Not expected, but a small amount of change is appreciated if they provide extra services like cleaning your windshield. - Porters/Hotel Staff: A small amount (e.g., 500-1000 ARS) per bag or for helpful service.

Budget Tips

  • 1Utilize Western Union: This is generally the most efficient and cost-effective way to get Argentine Pesos at a favorable rate. Plan to pick up money in larger towns.
  • 2Carry USD cash: Bring crisp, new USD 50 or 100 bills for exchanging at the blue dollar rate if you choose that method. Smaller denominations are useful for everyday spending.
  • 3Stock up on cash: Always carry more cash than you think you'll need, especially before venturing into remote sections of Ruta 40 where ATMs and card machines are non-existent.
  • 4Small denominations are key: Break down larger bills whenever possible, as smaller shops may struggle with change.
  • 5Fuel wisely: Always fill up your tank when you see a gas station, especially in Patagonia. Many smaller YPF stations require cash payment, or may have unreliable card machines.
  • 6Book accommodations in advance: If possible, pay for your car rental and some accommodations online in advance using a credit card to lock in rates and potentially benefit from the MEP dollar rate.
  • 7Self-catering: Consider buying groceries in larger towns and cooking some of your meals to save money, especially if staying in cabins or hostels with kitchens.
  • 8Tolls: Always carry small peso bills for tolls ('peajes'). While less common on Ruta 40 itself in Patagonia, some access roads or bridges may have them, and they are exclusively cash-based.

Frequently Asked Questions

Is it better to use USD or ARS on Ruta 40?

It's best to use Argentine Pesos for most daily transactions. However, having crisp USD 50 or 100 bills is highly recommended for exchanging to pesos at the favorable 'blue dollar' rate, typically through Western Union or trusted exchange points in larger towns. Some larger hotels or tour operators might accept USD directly for major payments.

How much cash should I carry for a road trip on Ruta 40?

You should carry a significant amount of pesos, especially between major towns. A good rule of thumb is to have enough cash for at least 3-4 days' worth of fuel, food, and any activities you plan to do, as ATMs are unreliable and card acceptance is spotty. Always top up your cash whenever you find a reliable source.

Can I pay for fuel with a credit card at all gas stations?

No. While larger YPF stations in major towns may accept credit cards, many smaller or remote gas stations along Ruta 40 are cash-only or have unreliable card machines. Always assume you'll need cash for fuel, especially outside of major hubs. It's crucial for managing your car rental expenses.

What about toll roads on Ruta 40?

Tolls ('peajes') are less common on the Patagonian section of Ruta 40 compared to other parts of Argentina, but some access roads or smaller stretches might have them. These are always cash-only and require small denominations of Argentine Pesos. Factor this into your cash planning.

Is Western Union safe to use in Argentina?

Yes, Western Union is a widely used and generally safe method for tourists to exchange money in Argentina, offering an excellent rate close to the 'blue dollar'. Be prepared for potential queues and bring your passport for identification. Always use official Western Union branches.

Are there any specific payment methods for car rentals?

Most major car rental companies will require a credit card (Visa or Mastercard) for the booking and a security deposit. Ensure your credit card has sufficient limit. However, for incidentals, fuel, and some smaller local rental agencies, cash may be preferred or required during your journey.

Should I be worried about counterfeit money?

While not common, it's wise to be vigilant, especially when dealing with informal exchanges. When receiving money, quickly check for watermarks, security threads, and textured printing. If receiving a large sum, try to do so in a well-lit area. When using official channels like Western Union, this concern is minimal.

What if my credit/debit card doesn't work?

Always have a backup credit card and plenty of cash. Inform your bank before travel about your plans to avoid fraud alerts. If a card doesn't work, it could be a machine issue, a bank block, or simply that the establishment is cash-only. Having diverse payment options is key.
