Uspallata Pass, Mountain pass between Argentina and Chile in Mendoza Province
Uspallata Pass is a mountain crossing through the Andes at approximately 3,832 meters (12,572 ft) elevation, linking Mendoza Province in Argentina with Los Andes in Chile. The Pan-American Highway and the Cristo Redentor Tunnel provide modern passage through this high-altitude route.
In 1817, General José de San Martín led military forces through this passage as part of the campaign to free Chile from Spanish colonial rule. This crossing became a key moment in South America's path to independence.
The Christ the Redeemer statue at this location symbolizes peace between the two nations and marks where people cross between countries. Visitors often pause here to acknowledge this shared monument and what it represents in the relationship between the peoples.
The high altitude and alpine weather mean visitors should prepare for mountain sickness, strong winds, and sudden weather changes. It helps to start the journey gradually and bring warm clothing regardless of the season.
From this mountain pass, visitors can see Mount Aconcagua, South America's highest peak at about 6,962 meters (22,841 ft), rising to the north of the crossing. On clear days, the summit comes into view and dominates the northern horizon.
