Argentina

Argentina’s seasons are reversed, and the country is big enough that "best time" is really a regional question. For Buenos Aires, Mendoza and the northwest, the spring (September–November) and autumn (March–May) shoulders are mild and uncrowded — the safe all-round choice. Buenos Aires summers are hot, humid and half-empty as locals leave; Iguazú is hot and humid year-round, a little easier in the shoulder months.

Patagonia sets its own clock: its summer, November to March, is the window when trails are open and excursions run, while winter largely closes it down. Add the seasonal highlights — Mendoza’s wine harvest (February–April, with the Vendimia festival in early March), the southern-right whales off Península Valdés (June–December) and Bariloche’s ski season (June–September) — and the pattern is clear: choose the region first, then the month.

For years the "blue dollar" parallel rate made bringing cash US dollars hugely advantageous. After the government lifted most currency controls in April 2025, that gap has largely closed — by 2026 the official and parallel rates sit within a few percent (around 1,500 pesos to the dollar), and foreign Visa/Mastercard now settle at roughly the market (MEP) rate, so cards are the easy, safe default. Chasing street changers, and the old Western Union edge, are no longer worth the trouble.

Cash dollars still have niche uses — some sellers and private landlords prefer them, and small vendors may not take cards — but they’re no longer the trip-defining advantage they were. Inflation is down sharply from its peaks but still high (~33% a year), so a quoted peso price can go stale within weeks. The one firm rule: this picture has shifted repeatedly since 2023, so re-check the current rates within days of travelling and before any large transaction.

Argentina is vast, and most domestic routes hub through Buenos Aires, so inter-regional trips often backtrack via the capital rather than connecting directly. Crucially, Buenos Aires has two airports: Aeroparque (AEP), right in the city, handles most domestic and regional flights, while Ezeiza (EZE) is the international gateway about 45 minutes out — leave generous time for any connection between them. The main carriers are Aerolíneas Argentinas and JetSMART, which overtook the shrinking Flybondi in 2025–26.

On the ground, Argentina’s long-distance "cama" buses are a genuine pleasure — fully reclining (even near-flat "suite") seats make overnight hauls civilised. In Buenos Aires you need a SUBE card for the Subte, city buses and trains (the Subte also takes contactless bank cards now); official black-and-yellow taxis and the Cabify app are legal, while Uber runs in a legal grey zone. In Patagonia, be ready for ripio (gravel) roads — much of Ruta 40 and its side roads are unpaved, with long gaps between fuel stations, so fill the tank at every chance.

The connection that catches people out is the two Buenos Aires airports: domestic flights use Aeroparque (AEP) in the city, but international ones use Ezeiza (EZE), about 45 minutes away through heavy traffic — so a same-day domestic-to-international hop means a cross-city transfer, not an airside connection. Give it several hours or, better, an overnight in the city. And in Patagonia, fill the tank at every station: much of Ruta 40 and its side roads are ripio (gravel) with long gaps between fuel stops.

The sensible trip picks two or three regions and flies between them rather than trying to join the dots overland. A classic two-week shape is Buenos Aires, a Patagonia leg (El Calafate plus El Chaltén, or Ushuaia), and one of Mendoza, Salta or Iguazú — booked around the fact that the south only opens in summer while the city and the northwest are at their best in the shoulders.

Go in the southern summer (November–March) and book well ahead: flights to El Calafate and Ushuaia, lodging in El Chaltén and the glacier excursions all sell out in peak season. El Calafate is the base for the Perito Moreno Glacier in Los Glaciares National Park; El Chaltén is the trekking hub beneath Mount Fitz Roy (3,405 m), with day hikes straight from town — though the park introduced a sector entry fee there in 2024, so they are no longer free. Ushuaia, the southernmost major city, is the jumping-off point for Tierra del Fuego and most Antarctica cruises.

One persistent confusion to clear up: Torres del Paine is in Chile, not Argentina. Pairing it with El Calafate is a popular itinerary, but it means crossing the border into a separate Chilean national park with its own rules and fees — plan it as an international leg, not an Argentine day trip. And note the summer paradox: Patagonia is at its windiest in the warm months, so pack for gusts even on a sunny day.

Natural-hazard caveat: wildfires hit parts of Patagonia in early 2026 and can close trails or parks at short notice in a dry, windy summer — check park (APN) and operator notices close to your dates.

Argentina’s national parks now charge foreign visitors far more than nationals — roughly double the resident rate at Los Glaciares, and up to seven times the local rate at Iguazú. The peso figures are repriced for inflation every few months, so the US-dollar equivalents (at ~1,500 ARS to the dollar) are the steadier guide. The table shows the headline gate prices as of late 2026:

Eat your way through the staples: empanadas, milanesa, choripán from a street grill, and dulce de leche in everything from alfajores to breakfast. The parrilla (steakhouse) is the set-piece meal — order a cut, let it come slowly, and pair it with a Mendoza Malbec. If someone shares mate with you, the etiquette is simple: drink it down and pass the gourd back without saying “gracias” unless you’re done for good.

Wine travel is easy to build in — Mendoza is the obvious base, with bodega visits a short drive from the city and the Vendimia harvest festival in early March, while Cafayate in the northwest offers some of the highest vineyards on earth. Buenos Aires itself is a serious food city, from Palermo’s restaurants to the old cafés notables.

Entry is straightforward: visa-free for 90 days for US, UK, EU, Canadian and Australian visitors (extendable once for about US$50), with no reciprocity or arrival fee since 2018. A mandatory-travel-insurance law has been on the books since July 2025 but has no implementing rules and isn’t checked at the border — carry insurance anyway. A yellow-fever certificate isn’t required, though the jab is recommended for the Iguazú region (Misiones/Corrientes). The emergency number is 911, and tap water is safe in Buenos Aires and the major cities.

Socially, Argentina is relaxed and liberal: same-sex marriage has been legal since 2010 — the first country in Latin America to do so — and Buenos Aires is one of the region’s most LGBTQ-friendly cities. Greetings are a single cheek kiss (men included), the Spanish is distinctive Rioplatense (vos instead of tú, “sh” for ll/y), and fútbol is a religion — a Boca–River Superclásico is the hottest ticket in the country. Above all, the pace runs late: lunch at two, dinner at ten, and the night just beginning at midnight.
