Major city · Argentina
San Juan
Give San Juan one full day for the centre and the dinosaur museum, then use it as a base for Ischigualasto or Barreal — not as a city break on its own.
San Juan is a low-rise wine city in a dry Andean valley, rebuilt on wide tree-lined avenues after the 1944 earthquake. The centre is walkable in half a day; the reason most travellers stop is the province around it — Ischigualasto (Valle de la Luna), Barreal and the Ullum reservoir. Flights from Buenos Aires take about 2 hours; the long-distance bus from Mendoza is about 3 hours.

- South America ↗Above 2,500 m (Bogotá, Quito, Cusco, La Paz) keep the first day light; sleep lower where you can (Sacred Valley before Cusco) and descend if headache comes with vomiting or confusion.
- South America ↗A yellow fever certificate is required on arrival in French Guiana, and asked for on some routes into Bolivia, Paraguay, Suriname and Guyana, or when arriving from Amazon areas — vaccinate at least 10 days before travel and carry the card.
- South America ↗Overnight buses are the norm in Argentina, Chile and Peru, but pick top-tier companies and keep valuables on your body; on-board thefts from overhead racks are the common loss.
- Argentina ↗Check entry rules for your passport with Argentina's National Migration Directorate (Migraciones) or an Argentine consulate before booking.
- Argentina ↗Since April 2025 the official, MEP and street ('blue') dollar rates sit within a few percent of each other; a foreign card is usually the best-value way to pay, while ATM withdrawals carry high fixed fees. Rules have changed often — check before you fly.
- Argentina ↗Patagonia (El Calafate, El Chaltén, Ushuaia) is a November–March trip; in winter many services close and hiking is limited.
- Argentina ↗Since August 2026 non-resident foreigners must show insurance or pay for non-urgent care at nationally run public hospitals, and Buenos Aires City, Mendoza, Salta, Jujuy and Santa Cruz charge visitors for scheduled care; emergencies are still treated. Travel with medical insurance — check the current rules.

Getting around
The centre is flat and walkable: Plaza 25 de Mayo to Parque de Mayo is about 2.5 km. City buses, taxis and remises cover the rest; remises are booked by phone or app rather than hailed. For Ischigualasto, Barreal or the Ullum reservoir you need a car, a tour or a long-distance bus.
