The mountain operator for people who want the Andes without Aconcagua's three weeks. They work the Cordón del Plata — the range you see from Mendoza city — with guided climbs of Cerro El Plata at 6,300 metres, trekking from Vallecitos, and day hikes around Penitentes.
El Plata is the classic acclimatisation peak for Aconcagua and a serious objective in its own right, while the Vallecitos treks suit anyone fit who wants a few days above 3,000 metres with a guide. They run trips in Spanish and English for groups, couples and families.
They publish no office address; the pin marks Vallecitos, where most of their trips start. Book by WhatsApp.
