A chill wind lifts off the high ridges as walkers climb toward a sharp, open viewpoint at 2,500 metres. The trail runs through sparse scrub and pumice-strewn slopes; behind, the Andean skyline is dominated by the bulk of San José Volcano — a 5,856 m peak that still shapes the ground beneath your boots.

History
The San José volcanic complex has shaped local settlement and travel routes; its last significant activity in the 20th century left fresh volcanic soils and visible lava deposits.
Conservation
The terraces and surrounding high-Andean vegetation are delicate; stick to trails, avoid soaps in pools, and pack out all waste to protect the thermal system.

Acclimatize before hiking
Spend a day in Santiago or San José de Maipo to reduce the risk of altitude effects before reaching 2,500 m.
Footwear matters
Wear sturdy trekking shoes with good grip for loose volcanic scree and uneven trail sections.
Protect from sun
High-altitude sun is intense — use SPF, sunglasses and a brimmed hat even on cool days.
Respect the terraces
Calcareous deposits form the pools; avoid standing on or scrubbing terraces to preserve them.
Sturdy hiking shoes
Essential for traction on loose volcanic scree and uneven trail surfaces.
Warm, windproof jacket
Temperatures can drop quickly at 2,500 m; a windproof layer prevents heat loss after the climb.
fall
Swimwear and quick-dry towel
Needed to enjoy the thermal pools; quick-dry fabric is convenient for changing.

Sun protection (SPF, hat, sunglasses)
