The Tour du Bastan is a 53 km technical route from Pla d'Adet (Saint-Lary ski area) to Vielle-Aure, centered on the Néouvielle reserve. The route's defining challenge is the Pas de la Crabe — a steep, scree-covered passage requiring careful footing on both ascent and descent. Runners cross the Hourquette Nère, climb to the Col de Bastanet (2,509 m — the highest point), and complete a circuit of the Bastan lake chain before descending to Vielle-Aure via the Col du Portet.
