At an elevation of 2 326m, the Cayolle Pass, located in the Val d'Entraunes, marks the border between the Alpes-de-Haute-Provence and the Alpes-Maritimes. Feel free to leave your car in the parking lot and stretch your legs. Many hikes are possible, including the Randonnée des 4 Lacs, our favourite on account of the superb views and the marmots that accompany you along the way.
