More ways to explore the area's outdoor wonders
You step off the transfer and the Andes take the volume out of the world: wind pushes at your jacket, scree talks underfoot, and a chain of raw ridgelines dares you higher. This single-day trek from Mendoza guides you into Vallecitos, where three distinct 3,000m-plus summits sit close enough to link in a long, demanding circuit. Expect steep approaches, rocky ridges, and open high-mountain meadows that reveal Aconcagua’s shadow on a clear day.

8–10 hours
Fitness Level
Good aerobic fitness and prior day-hiking experience at elevation; able to sustain steady climbs and descents for most of the day.
Wildlife
History
Vallecitos sits within corridors used for centuries by indigenous highland groups and later by shepherds; the area evolved into a mountaineering training ground as alpine sport grew in Mendoza.
Conservation
High-altitude ecosystems are fragile—stick to established routes, pack out all waste, and follow guide instructions to minimize erosion and wildlife disturbance.
Reserve your spot on the Trekking day in The Andes (from Mendoza) today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize in Mendoza first
Spend 24–48 hours at Mendoza elevation before the trek to reduce altitude effects; avoid heavy exercise the day prior.
Start before dawn
An early departure avoids afternoon wind and gives firmer snow/ice conditions on high slopes if present.
Bring sun and eye protection
UV intensifies above 3,000m—sunglasses (UV), high-SPF sunscreen, and a wide-brim cap are essential.
Pace for altitude and terrain
Move deliberately, use trekking poles on scree, and communicate symptoms of altitude sickness to your guide immediately.
Sturdy trekking boots
Support and traction for scree, rock, and mixed terrain across steep ascents and descents.
Layered insulation (fleece + wind shell)
Rapid weather changes demand a breathable mid-layer and a waterproof, windproof outer shell.
Sunglasses & high-SPF sunscreen
High-altitude UV is intense; protect skin and eyes throughout the day.
summer
Hydration system (2–3 L) and high-energy snacks
Sustained effort at altitude needs continuous hydration and quick calories to maintain pace.
