La Trochita, El "Viejo Expreso Patagónico"

La Trochita, (El Viejo Expreso Patagónico), in English known as the Old Patagonian Express, is a 750 mm (2 ft 5 1⁄2 in) narrow gauge railway in Patagonia, Argentina using steam locomotives. The nickname La Trochita means literally "The Little Narrow Gauge" in Spanish. It is 402 km in length and runs through the foothills of the Andes between Esquel and El Maiten in Chubut Province.

Originally it was part of Ferrocarriles Patagónicos, a network of railways in southern Argentina. Nowadays, with its original character largely unchanged, it operates as a heritage railway and was made internationally famous by the 1978 Paul Theroux book The Old Patagonian Express, which described it as the railway almost at the end of the world.

El Bolsón (during the "7 day challenge")

We start the day on our bikes for a ride at Cabeza Del Indio (mostly single track) where we enjoy the spectacular view of the Azul River Valley at the summit.

Get ready for a nice downhill ride as we head for lunch all the way to the river. After lunch we will hike to El Cajon del Azul, a spectacular refuge at 4,500 feet, where we will be received with mate, homemade bread and craft beer. Or you just can relax by the river. That same afternoon we will head on our vehicles to El Maiten, where a traditional asado (traditional Argentine barbecue) awaits.
