Polvorilla Viaduct (Viaducto de la polvorilla) Tours

Polvorilla Viaduct (Viaducto de la polvorilla)
The star attraction of Argentina’s famous Train to the Clouds (Tren a las Nubes) is the mighty Polvorilla Viaduct (Viaducto de la polvorilla). At an altitude of 13,842 feet (4,220 meters), the 20th-century viaduct is the highest point of the railway route and affords spectacular views over the surrounding Andes.

The Basics
Riding the Train to the Clouds over the Polvorilla Viaduct is an unforgettable experience, passing over a vast desert canyon. Travelers can ride a short section of the original Train to the Clouds railway between San Antonio de los Cobres and the Polvorilla Viaduct. It’s about a 2-hour round-trip journey, and the train stops at the viaduct for around 30 minutes, leaving plenty of time for photos. A popular choice is to take a day trip from Salta, stopping in the villages of Campo Quijano, El Alfarcito, and San Antonio de los Cobres along the way.

Things to Know Before You Go
  • Those who love train travel won’t want to miss a ride on the Train to the Clouds—it’s one of the highest railways in the world.
  • The total round-trip time for the Train to the Clouds is 2 hours and 45 minutes.
  • Trains go at a speed of just 20 mph (35 kph), leaving plenty of time to admire the scenery and take photos.
  • San Antonio de los Cobres and the viaduct are at high altitude—it is recommended that visitors spend a day or two acclimatizing beforehand.
  • The train is wheelchair-accessible.

How to Get to There

The Polvorilla Viaduct lies around 12.5 miles (20 kilometers) west of San Antonio de los Cobres along Route 40. Although it is possible to view the viaduct from the road, the only way to cross it is aboard the Train to the Clouds, which leaves from San Antonio de los Cobres station.

When to Get There
The Train to the Clouds has only two or three departures a week (normally on Thursday and Saturday), departing at midday, so be sure to plan ahead if you have your heart set on a ride. Bus transfers from Salta start from early morning.

Argentina’s Train to the Clouds

The Train to the Clouds was originally a 269-mile (434-kilometer) railway running from Salta to La Puna. Climbing through the Andes mountains, it includes 21 tunnels, 29 bridges, and 13 viaducts and passes through Cordillera de los Andes, Valle de Lerma, and Quebrada del Toro. Today, the only section of the railway in operation is the highest and most scenic section, from San Antonio de los Cobres to the Polvorilla Viaduct.
