Stretching about 100 kilometers, this challenging loop through the Drôme offers a diverse exploration of the Baronnies Provençales. It passes through several mountain passes, including the Col de Perty and its magnificent winding road lined with linden trees. From mid-June to mid-August, when the lavender fields are in full bloom, cyclists can look forward to an exhilarating ride with purple as far as the eye can see.
