The experience

You start before dawn. Meet at Plaza Antofagasta in front of Salta's train station at 6:15 am for check-in with your passport and ticket. The bus departs at 7:35 am heading toward San Antonio de los Cobres, climbing into the foothills of the Andes. Your first stop is Campo Quijano, 30 kilometers from the capital, where you see the C-14 railroad branch: an engineering landmark carved into the mountainside. At 8:05 am the bus stops at Viaducto del Toro in the Quebrada (gorge) of the same name, a second vantage point into the ravine.

By 9:25 am you arrive at El Alfarcito, a village at 2,800 meters elevation where local artisans keep traditional handicrafts alive. You eat a country breakfast here and walk through the craft fair, then visit the Father Chifri Foundation, an organization supporting education and training for the community. At 11:40 am you reach San Antonio de los Cobres and board the Train to the Clouds at the station. If you bought the train-only ticket, you join the group here. The train departs at noon, traveling at 35 kilometers per hour through open Andean landscape. On board, bar service, postal service and merchandise are available. Around 1 pm you arrive at the Polvorilla Viaduct: a steel structure 223.5 meters long, weighing 1,600 tonnes, standing 63 meters above ground at more than 4,200 meters elevation. This is the highest point of the C-14 railway branch. You have 30 minutes to descend, walk around the viaduct, and photograph it before reboarding for the return to San Antonio de los Cobres, arriving around 2:45 pm.

You then have two hours in San Antonio de los Cobres. The craft market is open, and you can make a clay pot with your own hands or arrange a trek with llamas (both optional and not included in the ticket price). Lunch is on your own. At 4:30 pm the bus departs for the return journey. After an hour's drive you stop at Santa Rosa de Tastil, home to one of Argentina's largest archaeological sites, estimated to have housed 3,000 people. You arrive back in Salta around 8 pm. A live guide in English or Spanish is on board the train throughout.
