Argentina Train to the Clouds Train

The Train to the Clouds, Argentina

The Train to the Clouds (or Tren a las Nubes) is a tourist train in North western Salta Province in Argentina – and the name says it all. It’s the fifth highest railway in the world, starting at the City of Salta (1,187metres above sea level) and climbing up the mountain to La Polvorilla (4,200 metres). Runs as a heritage railway, once primarily for locals, it’s Argentina’s most famous railway journey and is an incredible feat of engineering.

The entire journey completes a round-trip of 434km in 15 hours (with stops along the way), winding through 21 tunnels, over 13 viaducts and 29 bridges. Passengers are more than taken care of extremely well – hosted in carriages with comfortable seats, air-conditioning and bar and dining cars. While the entire round-trip takes 15 hours, most tourists just do a segment of the route.
