9–10 hours
Comfortable walking 1–3 miles at high altitude with brief hills; able to stand for scenic stops and handle a full day out.
Follow Route 7 from Mendoza into the high Andes, where Potrerillos Lake gleams, Puente del Inca glows, and Aconcagua commands the skyline. This private day trip balances scenic driving, a mellow high-altitude walk, and a wine-paired lunch for an approachable, all-in look at Argentina’s big mountains.
Dawn finds Mendoza waking slow and warm, while the highway to Chile points straight at the Andes like a dare. The Mendoza River runs alongside, restless and silver, pushing you west as vineyards give way to scrub and stone. By the time the road climbs to Potrerillos, the wind is talking—quick, cool sentences skimming the artificial lake where turquoise water holds back a mountain’s worth of melt. Cameras come out. Layers zip up.

Horcones sits near 3,000 m; hydrate early, eat lightly, and walk at a conversational pace to manage the thin air.
Rapid weather swings are common; pack a windproof shell, insulating layer, and sun protection even on clear mornings.
Carry a passport or government ID—there are occasional roadside checks along Route 7 near the border corridor.
Gusts at Potrerillos and Puente del Inca can be strong; secure hats and step carefully on exposed overlooks.
Puente del Inca hosted a famed early-1900s spa serviced by the Transandine Railway, which once linked Buenos Aires and Santiago through these valleys.
Aconcagua Provincial Park protects fragile alpine desert; stay on signed trails, pack out all waste, and give wildlife space year-round.
Mountain gusts and quick temperature drops are common, so a lightweight shell keeps you comfortable at viewpoints.
High-altitude sun is intense; full coverage prevents headaches and sunburn during midday stops.

The Horcones trail and roadside viewpoints can be rocky and dusty; grippy soles improve stability.
