Hiking in Colmars, France centers on the high, quiet country of the upper Verdon, where fortified Colmars sits below ridges leading toward Allos and the Mercantour edge. Les Tours du Haut-Verdon threads through alpine pastures, larch forests, and big open views above the valley, giving this corner of Alpes-de-Haute-Provence the kind of mountain depth that rewards hikers who want space, elevation, and long days on foot.
