About this experience

Follow Ruta 7, the freight road to Chile, from the irrigated valley up into bare mountain: the Potrerillos reservoir, the broad plain at Uspallata, and the thermal spring that built the ochre arch at Puente del Inca.

The road ends, for the day, at the viewpoint over the Horcones valley and the south face of Aconcagua.

Highlights
