Cajon del Maipo and San Jose de Maipo

Cajon del Maipo is the canyon of the Maipo River in the high Andes, about 50 km south-east of central Santiago in Chile's Metropolitana region, and San Jose de Maipo is its main village. The journey takes roughly 1.5 hours: visitors ride Metro Line 4 to Las Mercedes, then take the MB72A Metrobus or a colectivo to the village plaza, a trip of 60-75 minutes that costs about CLP 1,500-2,500. Drivers follow Ruta G-25 via Puente Alto and pay for parking in town. Organised day tours from central Santiago run at CLP 40,000-90,000 and often bundle rafting or a lunch stop. The canyon suits travellers who want mountain scenery without a long transfer. San Jose de Maipo itself has a small plaza, craft stalls and cafes, and the road beyond it climbs through San Alfonso, where visitors find riverside cafes, hot springs and adventure operators. River rafting on the Maipo starts from about CLP 35,000, and walking trails of varying length leave from several roadside points. A workable one-day arc begins with an early departure from Santiago to reach the village by mid-morning, followed by a walk around the plaza and a coffee. The late morning and early afternoon suit rafting, a hike or a hot-spring soak further up the canyon, with lunch at a grill or cafe in San Alfonso. The return bus or colectivo leaves in the late afternoon so that the descent finishes before dark. The best window runs from October to April, with wildflowers in October-November and warmer water for rafting in summer. Winter brings snow at higher altitude and occasional road closures. Food is simple and local: empanadas, grilled meats, trout and baked goods are common at stalls and family restaurants. Services thin out past San Jose de Maipo, so cash, water and sun protection are worth carrying. Weekends are busier on the road and at cafes, while weekdays are calmer.
