From the village of Les Aires, you will discover single trails and forest roads of the Saint Michel forest. The first section with a rising profile will take you to the chapel of Saint Michel, overlooking the ruins of the castle and the medieval village of Mourcairol (XIIth Century), from where you will enjoy a magnificent panorama of the Orb Valley and the Caroux mountain. Then you will run on technical ground to the high point before enjoying a more downhill descent to return to the starting point. A perfect route to combine discovery of local heritage and a training on varied terrain.
