THE ADVENTURE COLLECTIVE® · Independent discovery and booking for outdoor travel
Chain three 1,200+m summits above the pre-Andean valleys of San Juan in a single day. Expect steady climbs, loose scree, sweeping lake and peak views, and a full-day push requiring good fitness and sensible layering.

A cold wind brushes past as you step out of the van and onto stone-strewn slopes—three ridgelines rise ahead, each crowned above 1,200 meters. The route threads exposed grassy benches, compact scree fields and short steeps that test rhythm more than technique. From the highest shoulder the valley opens: blue lakes mirror serrated peaks of the pre-Andean range while low scrub whispers underfoot.

A cold wind brushes past as you step out of the van and onto stone-strewn slopes—three ridgelines rise ahead, each crowned above 1,200 meters. The route threads exposed grassy benches, compact scree fields and short steeps that test rhythm more than technique. From the highest shoulder the valley opens: blue lakes mirror serrated peaks of the pre-Andean range while low scrub whispers underfoot.
This part of Argentina’s San Juan province is shaped by uplift and erosion—ancient marine sediments folded by Andean tectonics now form the foothills known locally as the precordillera. Small ranching communities and stone cairns mark old herding paths; the landscape carries traces of rural mountain culture and seasonal grazing patterns.
Expect a full day on the move: steady uphill, occasional short scree descents, and three distinct summit moments separated by ridge runs. Weather can flip quickly in the precordillera—sun and wind trade places as you gain and lose elevation—and late-season snow can linger above 1,200 m.
Practical guidance: leave early to avoid afternoon winds, carry 1–2 liters of water per person plus a high-energy lunch, and wear grippy boots and layers for wind and sun. The operator includes private transport and bottled water; the outing is best for trekkers with solid aerobic fitness and some experience with long, continuous climbs. Move deliberately on loose sections, protect skin from strong mountain sun, and plan your descent with daylight in mind.
challenging.
6–8 hours.
Good cardiovascular fitness and leg endurance; comfortable with sustained uphill hiking and brief off-trail scrambling.
You should have a moderate to high fitness level—comfortable with several hours of continuous uphill hiking and repeated elevation changes.
No technical climbing gear is required; the route is a demanding trek with some exposure and short scrambling, not roped climbing.
Private transport, bottled water and an air-conditioned vehicle are included; confirm pickup point and bring food and personal layers.
The operator may cancel for poor conditions; they offer full refunds if canceled at least 24 hours prior and will notify guests if weather forces a change.
The precordillera was formed by complex uplift and folding of sedimentary layers during Andean compression; the area has a tradition of small-scale pastoralism and mountain guiding.
Stick to established boot tracks and avoid disturbing grazed meadows; water is scarce—pack out all waste and minimize single-use plastics.
