The minivan peels away from Santiago and the city’s concrete hum gives way to a narrowing valley: rivers begin to speak louder, and the Andes push the sky into a steeper blue. On this full-day excursion travelers move through the carved corridors of Cajón del Maipo—past shuttered railway tunnels and terraced farming plots—until the mountains open to thermal pools steaming against the cold alpine air.

Layer for dramatic temperature shifts
Bring a warm midlayer and a lightweight shell—the valley can be hot at midday near lower pools and cold in early morning or late afternoon.
Hydrate before and during the day
High-elevation sun and hot pools dehydrate quickly—carry a refillable water bottle and sip steadily.
Mind thermal pool etiquette
Observe posted signs: limit soak times in hotter pools and avoid soaps or oils to protect the mineral springs.
Plan for limited cell service
Download directions and meet-up details before you leave Santiago; Termas Colinas has little to no Wi‑Fi.
Layered clothing
A warmth-retaining midlayer plus a windproof shell handles valley temperature swings and alpine breeze.
Sturdy walking shoes
Closed, grippy shoes are useful for short walks, wet surfaces near pools and uneven village streets.
Refillable water bottle
Hydration is essential at altitude and after hot soaks—many operators stop for brief breaks but not constant water access.
Biodegradable sunscreen
Protects skin from strong mountain sun without harming sensitive pool and river ecosystems.
