On the way along the flanks of the Montbrison Massif, you will pass a small chapel tucked away in the hamlet of Les Combes. Built in 1718, the Chapelle Saint-Roch still bears the inscription above its entrance: “Passants, Saint Roch préservez-nous de la peste.” (“Travellers, Saint Roch, protect us from the plague.”) Saint Roch is known as the protector of travellers, pilgrims and the sick. The chapel is simple and humble, built from stone and wood, with a flat barrel vault and shingle roof — a quiet witness to centuries of passage through these mountains. As you ride past, pause for a moment. Try the doo... if it’s open.

Maximum point reached by both the road (in summer) and the chairlift (in winter) In all seasons, with good weather, a 360° spectacle guaranteed on the splendid peaks of the Dauphiné! the climb remains manageable up to approximately 100 m. below the arrival square of the lifts, here you arrive in double figures and you also need to push the bike a little, but the show pays off in a big way! for the descent you can choose the road or a route (S1-S2) which starts just below and which roughly follows the same itinerary. The road also has some challenging sections (uneven surfaces, potholes and steep sections) but overall it remains an S1. I haven't been able to evaluate the other tracks that start on the side of the dirt road, but I think there is something for all tastes... the only way is to try them!
