Beautiful footbridge to cross the stream of the same name near Le Villaret

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.
