Suitable for most active travelers comfortable walking 1–2 miles at altitude with brief inclines.
Trade the tour bus for a relaxed, small-group day into Aconcagua Provincial Park. Walk the easy Horcones Lagoon trail beneath the highest peak in the Americas, then cap it with a classic Argentine asado in Uspallata.
Dawn breaks over Mendoza as the Andes draw a hard blue line against the sky, inviting and a little intimidating. The road threads west up Route 7, past poplar windbreaks and vineyards giving way to rock and river. At Potrerillos Dam the water goes electric-turquoise, a still mirror that dares you to linger. Higher still, Uspallata offers a warm stop—coffee, a croissant, a last breath of low-elevation comfort—before the mountains take over the conversation.

Horcones sits near 2,900–3,100 m. Walk slowly, hydrate often, and skip alcohol until lunch if you’re sensitive to elevation.
UV intensity is fierce year-round—wear SPF 30+ and a brimmed hat even on cool days.
Carry a light windproof jacket and a warm midlayer; the valley can switch from calm to gusty within minutes.
Sturdy walking shoes or light hikers with good grip make the short loop more comfortable and stable.
This corridor carried pre-Columbian trails and, later, General José de San Martín’s Army of the Andes during the 1817 campaign for independence. Puente del Inca’s mineral arch once hosted a famed 19th-century spa along the trans-Andean route.
Stay on signed paths to protect fragile alpine soils and vegetation; wind makes litter highly mobile, so pack out all trash and favor refillable bottles.
Gusts funnel through the Horcones Valley; a shell keeps windchill in check.
High-altitude UV can burn quickly, even on overcast days.
Hydration helps manage altitude; refill in town to reduce plastic use.
Bright rock and snowfields amplify glare on the trail and at viewpoints.
