Chile Travel Guide: Santiago, Patagonia, Atacama in 2026

Citizens of around 90 countries — including all EU/Nordic countries, the UK, US, Canada, Australia, Japan, South Korea, Russia, and most of Latin America — can enter Chile visa-free for up to 90 days as tourists. The 90-day stamp can sometimes be extended by 90 more days through PDI (the immigration police) for around $100 USD. Citizens from non-exempt countries can apply for the e-Visa online or visit a Chilean consulate. Passport must be valid for the duration of your stay (Chile is unusually flexible on the 6-month rule). The SAG agricultural declaration on arrival is taken seriously — fines for undeclared fruits, seeds, or meat products start at $200 USD. Mercosur ID-card holders (Argentina, Brazil, Uruguay, etc.) can enter with their national ID alone. Compared to most of South America, Chile is on the pricier side, but services are reliable.

Chile spans over 4,000 km north to south, so timing depends entirely on the region. Patagonia (Torres del Paine) is only practical October to March — December–February peak, January–February for the long-daylight summer trekking; trails close from late April. Atacama Desert is essentially year-round but April–June and September–November are the sweet spots (avoid January thunderstorms, June nights are very cold). Santiago and wine country are best March–April (harvest season, Colchagua wine festivals) and October–November (spring, blooming Andes). Easter Island (Rapa Nui) is year-round but February is the Tapati Rapa Nui festival — the most important cultural event on the calendar. Ski season at Valle Nevado and Portillo: June–September. Seasons are reversed from northern hemisphere.

Chile demands time — 12–15 days minimum if you want Atacama, Patagonia, and one cultural region. The classic: Santiago (2 nights) — the Bellavista neighborhood, the Mercado Central seafood lunch, day trip to Valparaíso (colorful colonial port) and the Casablanca Valley wineries. San Pedro de Atacama (3 nights) — fly to Calama, then 90 min to San Pedro at 2,400m altitude. Day tours: Valle de la Luna at sunset, El Tatio geysers at sunrise (4,300m, very cold), Atacama Salt Flat with flamingos, Lagunas Altiplánicas. Torres del Paine (4–5 nights) — fly Santiago → Punta Arenas → bus to Puerto Natales → into the park. The full W Trek is 4–5 days; day-hikers can do the iconic Towers viewpoint in one day. Optional Easter Island (3–4 nights) via Santiago — 5.5 hour flight, the moai statues, Anakena beach, Tapati Festival in February.

San Pedro itself sits at 2,400m — mild altitude, most people are fine. But the key sights climb higher: El Tatio geysers at 4,300m (the day-tour starts at 4am for the steam plumes at sunrise — cold and exposed), Lagunas Altiplánicas around 4,200m, and the Chile–Bolivia border crossing tours peak at 5,000m. Three rules. Spend 24 hours in San Pedro before any high-altitude excursion — your body needs the time. Drink coca tea (legal here, traditional, helps) and skip alcohol the first day. Acetazolamide (Diamox) is the standard preventive — start 24 hours before going up. Locals also use soroche pills (sold in any pharmacy, around $5). Symptoms to watch: headache, dizziness, nausea, shortness of breath. If they worsen, descend immediately. Most visitors do El Tatio on day 2 or 3, not day 1.

Yes — Chilean wine country is one of the New World's most exciting, and the regions are easy to combine with Santiago. Three valleys to know. Casablanca Valley (1 hour from Santiago, cool-climate Sauvignon Blanc and Chardonnay, on the way to Valparaíso) — Matetic Vineyards, Casas del Bosque, Bodegas RE. Colchagua Valley (2 hours south of Santiago, the heart of Chilean Cabernet Sauvignon and Carmenère — the grape that was lost in Bordeaux and rediscovered in Chile in 1994) — Lapostolle, Viu Manent, Montes; base in Santa Cruz for 1–2 nights. Maipo Valley (45 min from Santiago, the historic heartland — Concha y Toro, Santa Rita, Almaviva). March is harvest season, the most atmospheric time to visit. Most wineries require advance booking, especially small premium producers.
