A few excursions also include a walk to the Termas de Colina thermal springs. You can take a dip in the six different pools and feel the rejuvenating water working wonders for both body and soul.

El Yeso Dam

The reservoir was created in 1964 when the El Yeso River was dammed. Today, the lake is a major water source for Santiago and a popular destination for tourists wanting an easy day tour to the Andean mountains.

El Yeso is famed for its turquoise waters, which perfectly complement the surrounding mountains. On a day trip to El Yeso Dam, you’ll be able to explore the shoreline, check out overlooks and hike to hidden cascades.

Termas de Colina

Heated by nearby San José Volcano, the thermal waters contain minerals to soften the skin and invigorate the body. A dip here is the perfect reward for all that hiking around the reservoir!

Tunel del Tinoco

This mysterious and derelict railway tunnel has its place firmly cemented in local folklore.

After the tragic suicide of a broken-hearted construction worker in 1998, the tunnel became a shrine. It’s said that his spirit will grant the wishes whispered by pilgrims who journey to the entrance.

You can walk through the tunnel to visit the shrine and see the archways from all angles.
