Mendoza Water Path: From Plaza San Martín to Lake Potrerillos
Select participants and date
Morning in Mendoza starts with a wind that carries dust and the Andes’ chill into the city. Stand at Plaza San Martín—under the statue of the liberator—and watch the town unfold westward: irrigation canals branching like veins across the dry plain, the Mendoza River tracking toward the mountains, and, beyond, Potrerillos Lake catching light on its hard surface. The tour moves with that geography, following meltwater from urban green spaces into a high-country reservoir and the steep-sided valleys around Cacheuta.

Adventure Tips
Hydrate before and during the trip
Carry at least 1.5–2 liters per person—altitude and dry air increase dehydration quickly.
Wear sturdy footwear
Trails around Potrerillos include loose scree and uneven surfaces; hiking shoes with grip are recommended.
Sun protection is a must
Even on cool days UV is strong; bring sunscreen, sunglasses and a hat for exposed sections.
Watch for altitude shifts
The route gains up to several hundred meters; brief light-headedness is possible—move slowly and communicate with your guide.
Local Insights
Wildlife
- Andean condor
- Patagonian hare (mara) and local passerine birds
History
Mendoza’s wealth grew from engineered irrigation systems that diverted Andean meltwater to the plains; the valley was a key staging area for General San Martín’s Andes crossing in the early 19th century.
Conservation
Water management is critical here—tourism must respect irrigation infrastructure and fragile high-altitude vegetation; stick to trails and avoid disturbing streambanks.
