Grande Séolane, Mountain summit in Alpes-de-Haute-Provence, France

Grande Séolane is a 2,909 m summit in the Alpes-de-Haute-Provence that closes the Barcelonnette basin to the southeast and overlooks the Ubaye valley. Its upper part is a steep wall of bare grey and tan limestone cut by vertical gullies and horizontal bands, with snow lying in the crevices; below, smooth snowfields are split by dark strips of exposed rock. The summit plateau is karstic, and the mountain's ridges mark the boundary of Méolans-Revel, Les Thuiles and Uvernet-Fours.

Grande Séolane is built from limestones of the sub-Briançonnais zone, a unit of the western Alps. Its summit is a limestone plateau on which karst relief has developed, with the rock dissolved into hollows and channels. The mountain rises as a massif enclosed on all sides by rock walls, closing the Barcelonnette basin to the south-east above the Ubaye valley.

The normal route leaves from the Col des Thuiles, with a short, easy climbing step just above the pass. A second marked itinerary climbs the south-east gully under its Occitan name, lou cheminet, where the rock is of poor quality and calls for care. Several climbing routes have also been opened on the surrounding walls, often at a high level.

The route from Col des Thuiles provides direct access with a moderate climbing section near the summit. Proper equipment and experience in steep terrain are needed to reach the top safely.

The southeastern path Lou Cheminet is a marked hiking route through characteristic limestone rock formations with its own name in the regional trail network. The trail requires care due to occasionally unstable rock.
