Select participants and date
Dawn loosens its grip on Mendoza as the van rolls west, vineyards giving way to ochre foothills and the river chattering beside Provincial Route 86. The mountains gather quickly here. Past Cacheuta’s stone tunnel and the blue plane of Potrerillos Dam, the Cordón del Plata rises like a stern teacher, its snowfields explaining exactly where the region’s water is born. The road aims higher, threading Andean valleys where the air turns sharp and the sky stretches thin.

Adventure Tips
Acclimatize and pace yourself
You’ll be hiking near 3,000 m; walk slowly, sip water often, and avoid heavy exertion if you feel lightheaded.
Bring pesos and your passport
Aconcagua Park charges an entrance fee in Argentine pesos and rangers will check your ID—carry your passport.
Dress for four seasons
Strong sun, cool shade, and gusty winds can hit in the same hour—pack a windproof layer, hat, and gloves.
Watch winter road conditions
Snow and black ice can close sections of Route 7; check updates and expect itinerary changes in mid-winter.
