Train to the Clouds

Salta serves as the departure point for a journey to the puna, or high-altitude desert. The 94-mile trip takes visitors from 3,280 feet above sea level to an altitude of 13,123 feet at San Antonio de los Cobres, where they board the main attraction: the Train to the Clouds. The railway reaches an altitude of 13,845 feet and runs along the amazing La Polvorilla Viaduct, which bends sharply into a camber curve tighter than a semi-circle.
