Valdrôme / Valdoule P'tites Routes du Soleil

From the Haut Diois area to the Oule Valley, the P’tites Routes du Soleil® crosses into the département, or French county, of Hautes-Alpes, skirting around the Crête des Dindarêts. The climb to the Col de Rossas (a pass at 1,125m) is regular. This is the only difficulty you’ll encounter before descending again to the Château de la Charce, once home to local 17th-century feisty fighting heroine Philis de la Charce. A deceptively flat-looking stretch takes you up the Oule Valley, known for its truffles. These local ‘‘black diamonds’’ are found around holm oak trees, harvested in winter, and renowned for their flavour, if you get the chance to taste them.
