The panoramic view of Lake Serre-Ponçon, along with the beauty of the lakes and the diversity of the landscapes encountered, make this hike, at the crossroads of the Ubaye and La Blanche valleys, an essential itinerary in the Alpes de Haute-Provence.
"The site of the Lacs du Col Bas is classified as a Sensitive Natural Area, a fragile site that is rich in biodiversity. It is important to stay on the marked trail (Decree of Biotope Protection No. 8–3106). You can find the arrêté de protection de biotope n°86-3106 for more information.
At Lac Noir, it is possible to descend to the Lac du Milieu, whose shores are lined with larch trees. Crossing the pastoral mountain of Clo Bas offers a completely different landscape, with exceptional plant and animal diversity. The ascent to the summit is done through an old military track that follows the mountainside.
