The currency is the Argentine peso, ARS. Foreign Visa and Mastercard usually get a tourist-friendly MEP rate close to the blue rate. That means cards are actually useful now, especially in Buenos Aires and bigger cities. Still, carry cash for kiosks, tips, transport cards, produce markets, nightlife, and smaller shops. ATMs are the weak point. They often have high fees, low limits, and sometimes no cash. Use them only as backup, and always refuse dynamic currency conversion. Western Union is still popular for cash, but lines, short hours, and empty branches are common. Do not leave the country with a large pile of pesos.

Argentina has four main travel climates. The northeast, Iguazú and Misiones, is hot, humid, and rainy for much of the year. Summer highs are often above 30°C and feel sticky. The center, Buenos Aires, Córdoba, Rosario, has clearer seasons. In May, days are roughly 15-21°C, while summers are hot and humid. The northwest, Salta and Jujuy, is drier. It has a summer rain season and cold nights at altitude. Patagonia is the least predictable area. It is cold, windy, and very seasonal. From late May to August, you can get freezing temperatures, snow, and limited transport or trail access.

The main real danger is petty theft, especially phone snatching in Buenos Aires. Keep your phone away from the hand nearest the street. Stay alert on buses, trains, and around Retiro, Constitución, San Telmo, and busy tourist streets. Distraction scams still happen, including the old mustard trick. Random people who stop you on the street are usually not worth your time. At night, walk with purpose and use Uber or Cabify instead of taking long walks in unknown areas. Rosario needs more care than most normal backpacker stops. Outside the biggest cities, places like Salta and Mendoza usually feel calmer.

Argentina is set up for long-distance buses and domestic flights. For buses, Plataforma 10 and Central de Pasajes are the easiest booking tools. Common companies on backpacker routes include Flecha Bus, Andesmar, Via Tac, Cata Internacional, and Via Bariloche. Overnight buses can be worth the extra money if you choose semicama or cama. In Buenos Aires, a SUBE card keeps buses, trains, and the Subte cheap. For long trips, especially to Patagonia, compare flights on JetSmart, Flybondi, and Aerolíneas Argentinas. Buses are slower and sometimes not much cheaper.

Health risk here is usually more about mosquitoes, weather, and altitude than serious food poisoning. Tap water is generally fine in Buenos Aires and many cities. In remote areas, some travelers prefer filtered or bottled water. Dengue risk gets higher after rain, especially in the north and green city areas, so use repellent, mainly at dusk. In the northwest, altitude can affect you badly above 2,500 m. Go up slowly and drink enough water. Public healthcare is available and usually decent in cities, but it can be crowded. Good travel insurance is still the wise choice.

Do not rush to buy an overpriced tourist eSIM if your phone can use a physical SIM. Claro and Personal are the most practical choices, and Movistar is also available. Claro tourist and prepaid options are strong. One reported tourist pack was 25 GB for 19,250 ARS. Other reported prepaid packs were 2 GB, 4 GB, 25 GB, and 40 GB. Personal had reported tourist packs from 5,400 ARS for 4 GB and around 10,000 ARS for 10 GB. Buy in an official store or an authorized kiosk with your passport. Coverage is good in cities and on main routes. It gets weaker in remote Patagonia and mountain areas.

Spanish is the main language, and Argentine Spanish has its own accent, slang, and the famous vos. Because of this, even decent textbook Spanish can feel a little strange at first. In Buenos Aires, many hostel staff, café workers, and tourist businesses can speak some English. In Mendoza, Bariloche, and the usual backpacker route, you also find basic English fairly often. Bus terminals, markets, small towns, and the northwest are more Spanish-only. A few useful phrases help a lot, especially for transport and money.

Argentina runs late, especially Buenos Aires. Dinner starts late, nights start even later, and people are often relaxed about time. This can test your patience if you think in a northern Europe way. Restaurant service is usually less active, so call someone over when you need help. Tipping around 10% in restaurants is standard, usually in cash. Bargaining is limited. You might do it a little at craft markets, but normal shops have fixed prices. People usually dress a bit smarter than the average hostel dorm style, especially at night. If mate appears, treat it as a social ritual, because that is what it is.

Food is heavy on beef, pasta, pizza, empanadas, milanesas, choripán, and medialunas, and regional differences are worth trying. In the northwest, empanadas salteñas and tamales are the right choices. In Buenos Aires, cheap lunches and simple meals can still be quite reasonable for backpackers. Better dinners get expensive quickly, especially in tourist areas. Medialunas were reported at around 1,500 ARS from a bakery, or about 3,500 ARS in a nicer café. Street food exists, but budget eating often works better with bakeries, set lunches, rotiserías, and grocery-store self-catering, especially outside Patagonia.
