High in the eastern flank of the Chilean Andes, the valley opens like a long breath: wind carries dust and resin, peaks cut a serrated horizon, and steam rises in pockets where the ground keeps its heat. Guests start before dawn from Santiago, climbing hairpin roads into Cajón del Maipo until the air thins and the landscape turns volcanic—rust-colored scree, hardy shrubs, and sudden stands of queñua.

High in the eastern flank of the Chilean Andes, the valley opens like a long breath: wind carries dust and resin, peaks cut a serrated horizon, and steam rises in pockets where the ground keeps its heat. Guests start before dawn from Santiago, climbing hairpin roads into Cajón del Maipo until the air thins and the landscape turns volcanic—rust-colored scree, hardy shrubs, and sudden stands of queñua.
The pools at Colina are fed by geothermal waters originating under Volcán San José; the area’s geology is recent and restless, shaped by Andean uplift and glacial scouring. Human history here mixes mining and rail transport—old train lines once supported Chile’s early industry—and today small mountain towns like San José de Maipo keep that working-mountain character alive. Wildlife is bold and visible: swift foxes slip between rocks and Andean condors wheel on the thermal winds.
Practically, the day combines a roughly 4 km trek at elevations approaching 2,500 m with time to relax in mineral springs that range from warm to near-boiling at source, tempered in constructed pools to comfortable bathing temperatures. The operator provides snacks, bottled water, an English-speaking guide, and transport in an air-conditioned vehicle. Expect variable temperatures—cold shade, intense sun on exposed slopes—and a moderate level of exertion; altitude can make an easy walk feel harder.
Bring a swim kit, layered clothing, sturdy footwear, sun protection, and a daypack with water. Plan for an 8-hour outing and a private pickup; for photographers the light around mid- to late afternoon can be especially crisp. The visit is both a natural soak and an introduction to the raw, volcanic edge of the Andes.
moderate.
8 hours.
Moderately fit — able to walk 4 km on uneven ground at high altitude; some experience with day hikes helpful
The trekking portion is about 4 km one-way with modest elevation change; the whole tour runs roughly eight hours including transport and pool time.
The tour visits managed thermal pools where the company provides access for the group; pools are communal rather than individually private.
The site sits near 2,500 m; mild symptoms (headache, shortness of breath) are possible—stay hydrated, avoid alcohol before the hike, and inform the guide of any concerns.
Yes — the private tour includes pickup and drop-off in Santiago in an air-conditioned vehicle; confirm your pickup point at booking.
The valley supported early Chilean rail and mining operations; tracks and mining ruins remain as reminders of 19th–20th century mountain industry.
Visitors are asked to pack out waste and avoid soaps in thermal pools; local operators promote low-impact visits to protect fragile alpine vegetation and water quality.
