About
Trail Walking of 10.5 km to be discovered at Occitania, Ariège, Bonac-Irazein. This trail is proposed by GuyVachet.
Description
Boucle dans la vallée d'Orle pour le sentier découverte Decauville à partir du parking de la Pucelle. Dans un premier temps, le GR T53 monte régulièrement en direction de Port d'Orle ce qui permet d’accéder au sentier Decauville à la cote 1280m. Ce sentier ombragé retrouve les vestiges de l'exploitation minière tant matériels qu'ouvrages d'art de la voie ferrée spécialement construite pour acheminer le minerai extrait du Mail du Bulard qui nous domine de 1500m. Au croisement avec le GR10, le reprendre pour une petite montée en direction de la Cabane du Besset afin d'avoir une belle vue d'ensemble de la vallée d'Orle. Redescente par le GR10 et le chemin de départ jusqu'au parking.
