Over 450 km, from the Atlantic to the Mediterranean, the Pyrenees have been crossed more than 30,000 times.
It is in the central part, between Catalonia and Aragon, from Val d'Aran (Province of Lérida) to Bielsa (Province of Huesca)
, that the most important itineraries are located. The French and Spanish partners have chosen to join forces on both sides of the mountain.
