The trail opens with the river's voice — Horcones Creek pushing you upriver through scrub and wind-bent willow to the high plain where Confluencia sits at roughly 3,400 meters. Cold light slices across talus slopes and the southern face of Aconcagua rises like a gray wall ahead, its glaciers and rock bands studying every step.

The trail opens with the river's voice — Horcones Creek pushing you upriver through scrub and wind-bent willow to the high plain where Confluencia sits at roughly 3,400 meters. Cold light slices across talus slopes and the southern face of Aconcagua rises like a gray wall ahead, its glaciers and rock bands studying every step.
This short but satisfying trek follows a route used by early mountaineers and local muleteers who supplied big expeditions in the 20th century. Geologically the valley is driven by Andean uplift and glacial sculpting; granite and metamorphic rock frame braided streams that dare you to keep moving. Culturally, the Horcones area is part of Mendoza’s mountain tradition — small ranger outposts, shepherd tracks, and the seasonal rhythm of guiding teams.
Expect wide views, occasional scree, and a small campground atmosphere at Confluencia: tents, cooking areas, and the constant wind that scours the plain. Wildlife is sparse but hardy — condors wheel, and vicuña may graze higher on exposed slopes.
Practical guidance: allow 8–12 hours depending on pace and acclimatization, carry layers for high-altitude wind and sun, and plan Aconcagua Park entry payment separately (paid at park office). Guides handle logistics and transportation from Mendoza; bring hydration, a warm insulated jacket, and shoes with good grip for alternating packed trail and loose rock. Start early to avoid afternoon winds and give your body time to adapt to altitude before heavier days on the mountain.
