Argentina's famous narrow-gauge steam train averages less than 30km/h on its meandering weekly journey between Esquel and Nahuel Pan – if it runs at full speed. In its current incarnation, La Trochita, which Paul Theroux facetiously called the Old Patagonian Express, is more tourist attraction than public transportation. It departs weekly in low season but almost daily in January and February.
Nahuel Pan is the first station down the line, 20km east. The trip takes 45 minutes. It's popular with groups so book ahead. For a small additional charge, you can organize with one of the Esquel travel agencies to return by minibus.
