Cerro de la Gloria is a rocky hill at the western end of Parque San Martín, rising above the park to give the best views of Mendoza and the Andes from within the city. A paved road and a footpath wind up to the summit, where the Monument to the Army of the Andes — a large bronze ensemble unveiled in 1914 — commemorates General San Martín's famous crossing of the Andes in 1817. The monument was cast from cannons captured during the wars of independence that followed.
On clear days the view from the summit is superb. The city spreads out to the east, and the snow-capped wall of the Andes fills the horizon to the west, with the profile of Aconcagua sometimes visible far to the north on the clearest winter mornings. The viewpoint is worth visiting at dusk when the light on the mountains is best.
The hill is the focal point for the Fiesta de la Vendimia celebrations each February. The Frank Romero Day Amphitheatre on the hill's lower slopes hosts the main harvest festival events, including the coronation of the Harvest Queen — a theatrical spectacle that draws visitors from across Argentina.
