Trade Santiago's skyline for high-Andean light on this private minivan day tour to El Yeso Reservoir and Termas Colinas. Scenic stops, short walks, and a thermal soak combine geology and local culture in a single day trip.

A low sun slants across serrated ridges as the minivan climbs out of Santiago’s dust and into the cooler breath of the Andes. The road tightens, the river seems to push the valley open, and El Yeso Reservoir appears — a sheet of alpine blue framed by raw granite and snow-scoured slopes. The guide eases the group to a roadside mirador; wind tugs at jackets, and the landscape hums with altitude.

A low sun slants across serrated ridges as the minivan climbs out of Santiago’s dust and into the cooler breath of the Andes.

The guide eases the group to a roadside mirador; wind tugs at jackets, and the landscape hums with altitude.
Cajón del Maipo is the upper basin of the Maipo River, a corridor shaped by glacial carving and volcanic lifts. El Yeso is an artificial reservoir built to secure water for the Santiago basin, its dam and road a modern footprint amid older ranching and mining routes. Termas Colinas sits higher still, where thermal water emerges along fault lines; locals have used these springs for muscle relief and ritual for decades.
Expect a day of short walks, panoramic stops, and a long soak — nothing technical, but altitude and sun are active players. The itinerary blends geology (rock faces and moraine) with culture (small Andean settlements and roadside vendors), and the guide often points out faint irrigation channels and century-old stonework.
Practical notes: leave bulky plans in the van, bring layered clothing, and stagger your water intake to counter altitude effects. Footwear should be stable on gravel pullouts and short slopes. The thermal pools range in temperature; enter slowly to avoid a rapid heart-rate change. Private transport means customized pacing, but permits and entrance to Termas Colinas are handled by the operator. Arrive prepared to exchange city heat for thin air, and a day that moves from cinematic views to quiet thermal recovery.
easy.
10 hours.
Suitable for people who can handle several short walks, standing at viewpoints, and a soak; no sustained hiking required.
The tour departs Santiago and typically takes about 1.5–2 hours each way depending on traffic and exact pickup location.
Hot springs have temperature ranges up to 55°C; people with heart conditions, pregnancy, or spinal issues should avoid high-temperature pools and consult their doctor.
Walking is light—short walks to viewpoints and to the thermal pools; no technical trails or long hikes are required.
Private transportation, guide service, and entrance to Termas Colinas are included; confirm food or additional fees with the operator.
Cajón del Maipo has long been a working corridor for irrigation, mining, and mountain access; El Yeso reservoir is a modern infrastructure project supplying water to the Santiago basin.
High-altitude vegetation and thermal ecosystems are fragile—stick to paths, avoid soaps in springs, and carry out all waste to limit impact.
TAC Turismo operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
