Tour de la Montagne de l’Ubac by mountain bike
Starting from the center of Ribiers, head toward the school and climb for several kilometers along a road and then a trail. This will take you to the Col de Couaïs, where you’ll descend into the Jabron Valley. A long descent along the trail gives you a chance to rest after the climb. Pass through the village of St-Martin and follow the trail to the St-Claude Chapel. A trail leads to Vieux Noyers. The atmosphere among the ruins is unique. Go around the church and continue on the trail. For a change of scenery, head back into the Buëch Valley via the Col de St-Pensier, then the Pas de St-Pensier. The trail is technical (with a few steps) and then smooth until you reach the dirt road. Head up the track, then turn right onto a smooth single track before reaching the Rocher de Pierre Impie. Caution: on the rest of this descent, there are many intersections and the trail is not always clearly visible; follow the markings carefully (same route as the PR—yellow—markings). The final few kilometers to Ribiers are on the road.
