San Antonio de los Cobres is a high-altitude town located in the Los Andes Department of Salta Province, Argentina. Situated at approximately 3,775 meters (12,385 feet) above sea level, it serves as a gateway to the Puna de Atacama region and is a key stop on the Tren a las Nubes (Train to the Clouds) railway line. The town's name, which translates to "Saint Anthony of the Coppers," reflects its historical association with copper mining in the surrounding Sierra de Cobre. Today, San Antonio de los Cobres is known for its indigenous culture, traditional weaving, and as a starting point for tourists embarking on one of the world's highest train journeys. ​ The Tren a las Nubes is a renowned tourist train that traverses the rugged terrain of the Andes, culminating at the Viaducto La Polvorilla. This impressive steel viaduct, located about 13 kilometers from San Antonio de los Cobres, stands at an altitude of 4,220 meters (13,845 feet) above sea level. Spanning 224 meters in length and reaching a height of 63 meters, the viaduct is a testament to early 20th-century engineering. Constructed between 1930 and 1932 under the direction of engineer Richard Maury, it was designed to overcome the challenging topography of the region. Today, the Viaducto La Polvorilla remains a highlight of the Tren a las Nubes experience, offering passengers breathtaking views of the Andean landscape. ​
