What to pack for a trip to Argentina?
What surprises most first-time visitors to Argentina is not the size of the country on paper but what it means in practice: a 20-hour night bus in a cabin chilled to near-freezing, then landing in a town where everything is shut until 17:00, then realising your plug doesn't fit and there's no adapter for sale.
In short, what catches you out here
- Argentina has historically had parallel exchange rates (official vs. blue/informal rate) creating confusion at ATMs and when budgeting; getting the best rate often requires cash transactions in person, and ATM withdrawal limits are low relative to fees.
- Argentina is the 8th largest country in the world; bus journeys between regions can take 20–30 hours, and domestic flights are expensive and sometimes fully booked weeks in advance if not reserved early.
- Many shops, pharmacies, and service businesses close from roughly 13:00 to 17:00 in smaller cities and towns, catching travellers off-guard when they need supplies or medication mid-afternoon.
Why this list?
Argentina rewards preparation not because it is dangerous or difficult, but because the gaps between its regions — subtropical north, high Andean altiplano, cold and windswept Patagonia — mean that what you need at one end of the country is almost the opposite of what you need at the other. Cash flow, domestic flight seats, baggage limits, and altitude acclimatisation all require decisions made weeks before departure, not on arrival. This list focuses on exactly those blind spots: the things that derail multi-week trips most often.
When to go
The Southern Hemisphere reverses the seasons: the austral summer (November to March) is the best time to visit Patagonia, Buenos Aires, and the Mendoza vineyards.
Less favourable : June to August
✔To do before you leave
Your countdown: every action at the right time, from furthest ahead to departure day.
- Domestic routes between Buenos Aires and Patagonia sell out weeks in advance during shoulder and peak season, and last-minute prices are prohibitive.
- Argentina's exchange rate situation changes frequently; arriving without understanding the current official vs. informal rate can mean losing significant value on every transaction.
- Allowances differ between Aerolíneas Argentinas and low-cost carriers, and between routes; being 1 kg over at a small Patagonian airport can cost as much as a separate ticket.
- ATM availability and withdrawal limits are much better in Buenos Aires than in Patagonian towns or remote north-west villages where cash is the only payment option.
- Spending a night in Salta city (1,187 m) before ascending to the high altiplano significantly reduces altitude sickness risk in the first days of trekking.
- Roaming costs in Argentina can be very high, and local SIM cards (Personal, Claro, Movistar) offer far better data packages for multi-week travel even if coverage remains patchy in the south.
- In smaller towns, pharmacies, supermarkets, and petrol stations close between 13:00 and 17:00; buying food, water, and any medication should happen before 12:30 to avoid a four-hour wait.
✔The essentials
Without these, the trip is compromised. Don't forget them.
- Mobile data disappears for hours in Patagonian parks, on Ruta 40, and in the Andean north-west; without offline maps, navigation on unmarked roads becomes genuinely dangerous.
- Argentina's Type I sockets are incompatible with UK, EU, and US plugs; adapters are rarely sold outside Buenos Aires and are expensive when found.
- The EHIC is not valid in Argentina; travellers departing from the UK or EU need separate travel insurance covering medical evacuation, which can cost thousands in Patagonia.
✔Nice-to-haves
Not vital, but noticeably more comfortable with them.
- Flying directly from Buenos Aires (sea level) to Salta then driving to Purmamarca at 2,400 m can trigger headaches, nausea and fatigue within hours; having a remedy on hand avoids losing a full day.
- Tap water quality varies sharply between provinces; in remote areas and small towns a filter removes the guesswork and avoids relying on expensive bottled water for a multi-week trip.
- Fitting clothing for both 35°C subtropical north and 8°C Patagonia into a single backpack or suitcase requires aggressive packing compression to stay within domestic baggage limits.
- Dry Andean air combined with high UV burns lips within a day on the altiplano; this is consistently the most overlooked item among first-time visitors to the north-west.
- Even lie-flat cama seats put awkward pressure on the neck over a 20-hour journey; the combination of neck pillow and eye mask (cabin lights flicker on at stops) meaningfully improves sleep quality.
- Hostels and bus stations often have a single free socket per room; charging phone, camera, and power bank simultaneously requires a multi-port adapter already fitted to a Type I plug.
- Offline maps, WhatsApp navigation, and translation apps run continuously in Patagonia where there are no plug sockets for an entire hiking day; a large capacity bank covers two full days off-grid.
- Domestic baggage limits mean main luggage often goes in the hold; a small daypack that fits under the seat keeps valuables, medication, and overnight items accessible during long transits.
✔Weather & season
Adjust to the time of year and forecast for your trip.
- Night buses air-condition the cabin to near-freezing; a thermal top makes the difference between sleeping and shivering through a 20-hour journey.
- Patagonian gusts regularly exceed 80 km/h; a standard rain jacket flaps open or inverts and provides no real protection, making a windproof membrane essential.
- UV radiation at 3,000–4,000 m in the Andean north-west and on Patagonian glaciers is extreme; standard SPF 30 applied once is not enough for a full day outdoors.

✔ Good to know
- Make sure your passport has at least 6 months of validity beyond your travel dates and at least two blank pages before you fly — border officers may turn you away otherwise. source
- Arrange travel medical insurance covering hospitalisation, emergency evacuation and repatriation before you leave home: since July 2025 Argentina asks non-resident visitors to show proof at entry points, and airlines may deny boarding without it. source
- Bring a mix of payment methods: credit/debit card (Visa or Mastercard are widely accepted and use a favourable MEP exchange rate) plus some crisp, post-2013 USD 100 or EUR 100 bills for small venues, tips and markets that prefer cash. source
- Expect steep ATM fees and low withdrawal limits from local machines; relying solely on ATMs can be costly, so plan your cash needs before you go and exchange at a reputable bureau rather than at the airport or a hotel. source
- Pack a universal travel adapter: Argentina uses Type I (angled flat-pin, common in Australia) and Type C (Europlug), at 220–230 V / 50 Hz — not compatible with US appliances without a voltage converter. source
- Check your visa status well before departure — entry rules vary by nationality and Argentina updated them in July 2025; some nationalities (e.g. Chinese and Indian passport holders) may need an AVE authorisation or a visa sticker depending on whether they hold a valid US visa. source
- Worn or damaged banknotes — Consider bringing only pristine, post-2013 large-denomination USD or EUR bills: exchange bureaux routinely decline torn, written-on or older notes, leaving you with unusable cash.
- US-style two-flat-pin (Type A/B) chargers without an adapter — Argentina uses Type I and Type C sockets at 220–230 V, so North American plugs won't fit and devices rated for 110 V could be damaged without a voltage converter.
- Large rolling suitcase for Patagonia trekking — Remote lodges and mountain trails have very limited storage; a compact backpack or soft duffel tends to travel much better on the uneven terrain and small transport links typical in Patagonia.
✔ Frequently asked questions
Is tap water safe to drink in Argentina?
Buenos Aires tap water is treated and generally considered safe to drink, but water quality becomes less reliable in provincial cities and genuinely variable in remote areas of Patagonia, the Andean north-west, and rural north-east. For a multi-week trip covering several regions, a portable filter or purification tablets remove the uncertainty and reduce reliance on single-use plastic bottles. When in doubt, ask locally.
What is the best way to get around Argentina on a multi-week trip?
For long distances (Buenos Aires to Patagonia, Buenos Aires to Salta), domestic flights are the only realistic option time-wise, but they should be booked weeks in advance as seats fill quickly and prices spike. For medium distances (between Patagonian towns, along the Andean north-west circuit), long-distance cama buses are comfortable and affordable if you prepare for the cold cabin. For Patagonian parks like El Chaltén and El Calafate, local transfers and rental cars are the main options, and road conditions in winter can require snow chains.
What should I pack differently depending on when I visit Argentina?
Argentina's seasons are reversed from the northern hemisphere: December to February is peak summer in the north (hot, humid, occasional flooding in Iguazú) and the best hiking season in Patagonia. June to August is winter in Patagonia with shorter days, possible road closures, and many park facilities closed, while the Andean north-west is dry and clear. Whatever the season, packing for both subtropical warmth and Patagonian cold in a single bag is the core challenge; layering with a compact but genuinely windproof outer shell is the most practical approach for a trip spanning both regions.
How serious is altitude sickness when visiting the Andean north-west of Argentina?
Flying from Buenos Aires (sea level) directly to Salta and then driving the same day to Purmamarca (2,400 m) or the Salinas Grandes (3,450 m) is a very rapid ascent and symptoms like headache, nausea, and fatigue are common. Spending one night in Salta city before ascending higher helps the body adjust. Many travellers carry a remedy (consult a travel health clinic before departure) and avoid alcohol and strenuous activity on the first day at altitude.
Are night buses in Argentina actually comfortable for long distances?
The cama class (fully or semi-reclining seats) on Argentine long-distance buses is genuinely more comfortable than standard coach seats and includes a meal service, but the cabin temperature is kept extremely cold by Argentine standards of comfort. Bringing a thermal layer and a travel blanket in your daypack rather than in the hold makes a significant difference over a 15–20 hour journey. Book cama seats as early as possible on popular routes like Mendoza–Bariloche or Buenos Aires–Córdoba, especially during January and Easter week.
