Description: Shortly after leaving the Tourist Office of Mons, you will see the signposting which invites you to leave the Voie Verte. From paths to small roads, you first reach the Verdier Bas, then by a small rise, the Hameau de La Coste. The tiny road takes you to the bottom of Saint Martin de l'Arçon and its town hall. The track is shaded. At St Martin, the climb gives way to the descent to La Pomarède, the first hamlet of Colombières sur Orb. After a picturesque crossing, you descend along a small playful path towards La Borie, then Aire Vieille. At the lowest point, you join the Voie Verte which takes you back to Mons. The small passage in the Tunnel will allow you to refresh yourself during the hot weather.
