Overview
The Cajón del Maipo is the valley of the Maipo river, running into the Andes south-east of Santiago. The road climbs past orchards and villages such as San José de Maipo, into a steep, narrow valley with the Volcán San José (5,856 m) at its head.
It is a classic weekend escape for people from the capital. Activities include rafting on the Maipo, day walks, horse riding, hot springs and stargazing, and the road continues to Baños Morales, Embalse El Yeso, with its turquoise reservoir, and high viewpoints. Wildlife includes Andean condors, which often circle above the valley.
Highlights
- Embalse El Yeso, a turquoise reservoir at about 2,500 m
- Hot springs such as Baños Morales
- Rafting on the Maipo river
- Villages such as San José de Maipo, with markets and cafés
Best time to visit
October to April is the main season, with warm days and open roads. January and February are very hot at lower levels. Winter brings snow and closes the upper road, but the lower valley remains accessible.

Getting there
Fly to Santiago (SCL), then drive about 1.5 hours to San José de Maipo, or take a metro and bus. Day tours run from Santiago. The road to the upper valley is mountainous, and some areas require permits or fees, so check local conditions.
What to expect
Easy to moderate. Many sights are close to the road, and walks are of all lengths. Altitude, sun and heat can be strong. Weather in the high valleys changes quickly.
Practical tips
- Check road and reservoir access, as some sections have restrictions.
- Carry water and sun protection, even on cool days.
- Book rafting and hot springs with licensed operators.
- Plan to return before dark, as the road is winding.
