Abra del Acay, Mountain pass in Salta Province, Argentina.
The Abra del Acay road pass reaches an elevation of 4,956 meters, making it the highest navigable point along Argentina's National Route 40.
The construction of this mountain pass began in 1943 and concluded on July 8, 1960, funded by both the National Roads Directorate and Salta Province.
The pass connects the wine-producing Calchaquíes Valleys with the Puna Plateau, serving as a vital link between these distinct geographical regions.
Travelers need to carry repair equipment, food, water, and a full fuel tank due to limited services and absence of cell phone coverage.
The narrow gravel road through Abra del Acay presents extreme conditions with strong winds and an oxygen-depleted environment at high altitude.
