The landmarks, rooms, and views travelers on this tour remember — all visible on a single visit.
A massive structure offering direct views of the turquoise waters and Andes peaks. It is the primary viewpoint for the entire reservoir.
A hiking route requiring a certified guide that showcases high-altitude mountain scenery. It offers a more immersive nature experience than the main viewpoint.
The best spot to photograph the intense blue hues of the water against the snow-capped mountain backdrop. This area is easily accessible for most visitors.
These destinations complement one another; visitors typically find the reservoir better for expansive Andean vistas while the springs offer superior physical recovery. Securing embalse del yeso termas tickets allows you to balance high-altitude sightseeing with geothermal soaking.

Follow Route G-25 to Route G-455; 4x4 strongly recommended.
Dress in multiple layers to adapt to rapidly changing Andean temperatures. Sturdy, closed-toe hiking shoes are essential for the rocky terrain around the reservoir.
No formal bag checks are in place, but maintain possession of your belongings at all times. Secure your vehicle if parking near the dam curtain.
Photography is permitted and highly encouraged from designated viewpoints. Using a tripod is helpful for capturing the turquoise water against the mountains.
The natural, rocky terrain is not suitable for wheelchairs or individuals with limited mobility. Viewpoints are reached via unpaved paths.
Mobile signal is extremely intermittent or non-existent in the canyon. Download offline maps before leaving San José de Maipo.
Families are welcome, but the high altitude (2,500m) may impact young children. Supervise minors closely near the reservoir and steep drop-offs.
No dining facilities exist directly at the reservoir. Bring all necessary water and food or plan for a picnic as part of a guided excursion.
Pets are discouraged due to the harsh high-altitude environment and wildlife protection. Check with specific tour operators if you must bring one.
Ensure your vehicle has sufficient fuel before leaving the town of San José de Maipo, as there are no services nearby. Altitude sickness can occur; stay hydrated.

The Embalse El Yeso sits at 2,500 metres, a reservoir constructed in 1964 to supply Santiago's growing population with meltwater from the Andes. Its dam, a 58-metre curved concrete wall, holds back glacial runoff that pools in a basin ringed by sedimentary peaks still dusted with snow through November. The water reads turquoise under midday sun — a trick of suspended limestone particles — and the reservoir stretches six kilometres into a valley where no road continues. What draws visitors beyond the reservoir itself is the convergence of high-altitude geography and geothermal activity less than fifteen kilometres downstream. The Cajón del Maipo corridor, carved by the Maipo River over millennia, exposes faultlines where mineral-rich thermal water surfaces naturally. Colina hot springs, a cluster of stone-lined pools fed by these aquifers, sits at the junction of canyon trails leading both to the Yeso watershed and deeper into Andean backcountry. Tour operators began pairing embalse del yeso termas itineraries in the early 2010s, recognising that the two-hour drive from Santiago could encompass both alpine scenery and a thermal soak within a single day. The reservoir itself is accessible only Friday through Sunday, a schedule imposed in 2018 to limit erosion along the gravel access road and reduce foot traffic across unstable scree slopes near the shoreline. Entry requires a 5,610 CLP conservation fee for foreign adults, collected at a ranger checkpoint five kilometres below the dam. Most arrive between 08:00 and 10:00 to secure roadside parking — the final three kilometres narrow to a single lane with limited pullouts. Wind picks up after 14:00, turning the reservoir's surface opaque and dropping temperatures sharply. Thermal pool infrastructure varies. Colina's main circuit comprises four pools at temperatures ranging from 32 to 42 degrees Celsius, each enclosed by dry-stacked basalt and fed by gravity flow from upstream springs. The water carries dissolved magnesium and calcium sulphate, leaving a white residue on stones and a faint mineral odour. Tours that include both embalse del yeso termas experiences typically allocate three hours at the reservoir and ninety minutes at the thermal site, with picnic provisions served at designated canyon viewpoints. The route back to Santiago retraces the same valley, descending 1,800 metres through switchbacks that open onto the city's eastern suburbs by early evening.
"The water reads turquoise under midday sun — a trick of suspended limestone particles — and the reservoir stretches six kilometres into a valley where no road continues."
A step-by-step walkthrough of the visit — what you'll see, how long each stage takes, and the details that matter.
You leave Santiago before sunrise, the van climbing through canyon walls still shadowed in pre-dawn blue. By the time you reach the ranger checkpoint at El Yeso, the first light is catching the peaks overhead. You pay the 5,610 CLP conservation fee and continue the final gravel stretch, the reservoir appearing suddenly as the road crests a ridgeline — a flat mirror of turquoise wedged between scree slopes and snowfields. You walk the shoreline trail, stones crunching underfoot, the air thin enough that you pause to catch your breath every few hundred metres. The water is too cold to touch. Wind starts to stir the surface by mid-morning, and you return to the vehicle as other groups arrive. The descent takes you back through the canyon to Colina, where the thermal pools are terraced into a hillside above the river. You change in a stone shelter and step into the first pool — 38 degrees, warm enough to soften the chill still in your legs from the altitude. The second pool runs hotter, 42 degrees, steam rising into the dry mountain air. You soak for an hour, the only sound the trickle of spring water refilling the basins. By late afternoon you are back on the valley road, the Andes receding behind you as the city reappears below.
