Nice relax and shower stop in the swimming pool by Parc de'Espagne. Also a hose to clean the bikes in park near the gondola lift entry.

The Col de Pailhères isn't the most well-known of the Pyrenean passes, yet it's a concentration of everything cyclists are looking for. From Ax-les-Thermes, the slopes of this hors catégorie route constantly vary, requiring constant adjustments to finish at an altitude of over 2,000 meters in a superb setting.
