The trail opens with the Andes breathing cold air into the valley as you leave the ski-club parking and step into the Quebrada del Estudiante. Low scrub and stands of cacti give way to steep switchbacks; the path climbs steadily, each bend revealing a broader sweep of Potrerillos Lake glinting like a blue shard below. The summit of Arenales stands as a clear objective: a rocky ridge that demands steady legs and attention to footing.

Start early
Begin at first light to avoid afternoon wind and to catch clearer views of the lake and surrounding peaks.
Carry at least 2–3 L of water
High sun and dry air in the Mendoza Andes increase dehydration risk—bring more water than you think you'll need.
Use trekking poles
Poles help on loose scree near the summit and reduce impact on the knees during the descent.
Layer for sudden cold
Wind and exposure at the ridge can drop temperatures quickly—pack a light insulated layer and a wind shell.
Sturdy hiking boots
Support and traction on dirt trails and loose scree near the summit.
Trekking poles
Improve stability on steep sections and protect knees on the descent.
Sun protection (hat, SPF, sunglasses)
High solar radiation and reflection from rock demand reliable sun protection.
summer
Insulating jacket & wind shell
Lightweight layers keep you warm on exposed ridges where wind can be strong.
