Andes Hiking from Santiago: What to Know

Expect a solid day trip that gets you out of the city smog and into real Andean scenery within 1–2 hours of driving. Most hikes are moderate: think 4–8 hours of walking on good trails with views of jagged peaks, glacial valleys, and sometimes condors. Altitude starts around 2,500–3,500 m, so you’ll feel the thinner air; headaches and faster breathing are normal. Groups are small (6–12 people), transport is usually a comfortable van, and guides handle logistics so you just walk. Weather can shift fast—sunny mornings can turn to cold wind or light snow even in summer.

The best time is November to March when days are longer, warmer, and trails are mostly snow-free. Shoulder months (Oct, April) are quieter and cheaper but can be colder or wetter. Expect to pay around $80–$180 per person for a full-day guided hike including transport and lunch; half-day options run $50–$90. Private tours sit at the higher end.

Pick the Cajón del Maipo route if it’s your first time—it’s the most scenic and reliable. Skip volcano “summit” day-tours unless you’re very fit and acclimatized; they’re long, crowded, and often more driving than hiking. Bring your own water bottle, layers, sunscreen, and a good hat. If you get altitude headaches easily, take it easy the first 24 h in Santiago.
