Salta-Jujuy

Salta-Jujuy is a 620-kilometer gravel ultra-cycling event starting in the city of Salta in northwestern Argentina, traversing the dramatic high-altitude landscapes of the Salta and Jujuy provinces toward the Bolivian border. This region of Argentina is renowned for its extraordinary geological diversity, including the multicolored rock formations of the Quebrada de Humahuaca — a UNESCO World Heritage Site — alongside high Andean plateaus, salt flats, and dramatic canyon systems carved into vividly striped sandstone. The altitude in this part of the Andes is significant, with much of the route likely climbing well above 3,000 meters into the puna, the high desert plateau characteristic of the Argentine northwest.

The combination of extreme geological color, high-altitude desert terrain, and the rich indigenous and colonial history of the Salta and Jujuy provinces makes this one of the most visually striking regions in South America for an ultra-cycling route. The September timing falls within the Southern Hemisphere's late winter to early spring, generally offering dry and stable conditions in this arid high-altitude region, though riders should expect cold temperatures at elevation, particularly overnight.
