The Greenway of the Gaves

The Greenway of the Gaves – Voie Vertes in French – provides you with a car-free cycling route to travel from Lourdes along the Vallée des Gaves. Formed from a disused railway line originally constructed at the end of the 19th Century, it was designed to take travelers to the spas located in Luz Saint-Saveur and Cauterets. The now transformed rail-trail is 18.6kms long and takes in the 12 villages dotted between Lourdes and Piereffite-Nestalas.

It is a great option for families and being a disused railway line is a relatively flat riding option. Along the route are information signs which we recommend stopping to read so you can discover the history of the towns in the valley. We have often used the rail trail when returning back to Argeles Gazost from longer rides in the higher mountains and found it a good way to spin the legs out after a harder ride. Be mindful the rail trail is also a shared path for pedestrians and roller-bladers alike so be courteous to other users.

Even though the rail trail is almost completely flat, reminders of the Tour de France are never too far away.
