4 Best Sights in Cajon del Maipo, Side Trips from Santiago

These hot springs high in the mountains at 3,500 meters (11,483 feet) above sea level are a series of natural pools down which water drops, cooling gradually. The road is rough and often impassable in winter and there is little infrastructure, but the view and clear skies are spectacular, including from the astronomical observatory located here. Rustic lodging and camping is available. Do not confuse these rustic springs with Termas de Colina, which are similarly named but located north of the city.

Two pools in the tiny village of Baños Morales, where the Morales and Volcán rivers meet, are pleasantly warm, not hot, and rich in iodine and other minerals. You can hike from this area as well. Be warned that surprise winter storms can trap you here. The village has some rustic lodging, but many people prefer to come for the day.

This small tourist complex in the shadow of the mountains has a swimming pool and picnic area for short stays, as well as lodgings for longer sojourns. This is also a great base for exploring the Cajón. Accommodations come in several forms, including campsites, lodge suites, and freestanding cabins with rustic wood furniture. From here, multiday horseback-riding trips, guided hikes, and rafting excursions are available, as is transportation from Santiago.

The Alemán Lo Valdés Mountain Center, built in 1932, provides basic, well-priced lodgings and organizes activities such as trekking and horseback riding in the mountains. It is open year-round and has a restaurant that also serves day visitors until 8 pm; meals won't cost more than 9,500 pesos. If you'd prefer to do your own hike, the center can give you a map and instructions.
