Multi-Day Trips: Santiago as Your Hub
Chile is 4,300 km long and shaped like a ribbon, which means almost nothing near Santiago is reachable in an afternoon and almost everything worth seeing is a short flight or a long, spectacular bus ride away. Treat the city as base camp and pick one direction.
North: San Pedro de Atacama
LATAM, SKY and JetSMART fly SCL to Calama (CJC) in about 2 hours, from USD 40-120 one way, followed by a roughly 75-minute shuttle to San Pedro itself, sitting at 2,400 meters. Budget 3-5 days for Valle de la Luna, the El Tatio geyser field at 4,320 meters (a pre-dawn departure to catch the steam at its most dramatic), and the salt flats stretching toward the Bolivian border. This is genuinely high altitude, unlike Santiago itself, so build in a slow first day.
Check Atacama multi-day packages if you want lodging and desert excursions bundled together.
South: Chilean Lake District
A 100-minute flight from SCL lands you in Puerto Montt (PMC), gateway to Lake Llanquihue, the cone of Osorno Volcano, and Vicente Pérez Rosales National Park. Base yourself in Puerto Varas for 3-4 days, and if time allows, cross by ferry and bus to the wooden UNESCO churches of Chiloé Island. This is the greenest, wettest version of Chile you’ll see on a short trip, a real contrast to the dry central valley you’re leaving behind.
Far south: Torres del Paine
The 3.5-hour direct flight from SCL to Punta Arenas (PUQ) or the seasonal route to Puerto Natales (PNT) is the gateway to Chilean Patagonia. The “W” Trek runs 4-5 days; the full “O” Circuit closer to 7. Season is October through April; outside that window, wind and snow close much of the park infrastructure. Park entry, refugio booking and current trail status are all on parquetorresdelpaine.cl ; book refugios and campsites months ahead in peak summer (January-February), since capacity is limited and controlled.
Look into Torres del Paine trekking packages for logistics support on the W or O circuits.
East: overland to Mendoza, Argentina
Skip the flight and take the bus: Turbus, Andesmar and Cata Internacional run the Terminal Alameda to Mendoza route in 7-8 hours for USD 35-55 each way, climbing the switchback Caracoles road over Paso Los Libertadores at 3,200 meters, with Aconcagua visible along the way, before dropping into Argentina’s Malbec country. Bring your passport and expect a border stop with luggage checks; winter snow can delay or close the pass, so build slack into a return itinerary in July and August.
Planning notes
None of these routes overlap well with each other in a single week, so pick one region rather than trying to stack Atacama and Patagonia into the same trip. Domestic flights within Chile are cheapest booked 3-6 weeks out on carriers listed at latam.com , and December through February is peak season across all four directions, meaning higher fares and fuller refugios. If you’re combining a multi-day trip with more Santiago time before or after, this site’s Santiago day trips guide covers the shorter options closer to the city, and a Metro Bip! card (CLP 1,500, top-ups in CLP 1,000 increments) is worth having ready for the day you land back at SCL.
