A full-day escape from Santiago into Cajón del Maipo: a 4 km high-altitude hike to a San José Volcano viewpoint followed by thermal terraces at Baños de Colina. Expect stark volcanic scenery, lime-formed pools and a restorative soak.
More ways to explore the area's outdoor wonders
You leave Santiago before dawn and the city light thins into scrub and then granite. The road climbs into Cajón del Maipo, and after an hour or two the Andes dominate the window—raw talus slopes, dark volcanic ribs and the looming cone of San José. The guided route gains about 300–400 meters over a 4 km out-and-back to a high viewpoint at roughly 2,500 m, where the volcanic complex and glacial cirques read like a geological atlas.

Acclimatize and hydrate
Drink water before and during the hike—altitude around 2,500 m can amplify fatigue and dehydration.
Wear sturdy shoes
Rocky, uneven trail sections and short steep pitches require hiking shoes with grip.
Protect from high-altitude sun
UV is stronger at 2,500 m—bring sunscreen, sunglasses and a wide-brim hat.
Bring a towel and quick-dry swimwear
Pools are natural and temperature-variable; a towel and modest swimwear make the soak comfortable.
Hiking shoes
Stable grip for rocky alpine trails.
Layered jacket (windproof)
Wind and temperature drop quickly at 2,500 m.
Sun protection (sunscreen, hat, sunglasses)
High-altitude UV protection is essential year-round, especially in summer.
