Pic de Séron, Mountain summit in the French Pyrenees, France.

Pic de Séron is a mountain summit in the French Pyrenees located between the communes of Aulus-les-Bains and Ustou in the Haut-Salat region of Ariège. The peak rises to about 2.489 meters and dominates the landscape with its position between important mountain valleys.

The summit lies exactly on the municipal boundary between Aulus-les-Bains and Ustou, in the Haut-Salat area of Ariège. That boundary line, not a building or event, is the peak's documented administrative role: it separates two communes of the Couserans. The summit rises to 2,489 m and is the highest point of this stretch of the dividing ridge.

The peak stands on the boundary between Aulus-les-Bains and Ustou, in the Haut-Salat of Ariège. Its slopes overlook the cirque de Cagateille and the Guzet ski area, whose Freychet sector lies close by. The Turguilla cabin, at 2,078 m south toward the étang de Réglisse, has seven bunk beds.

Hikers can reach the summit via the southern slope trail which leads through meadows before joining the ridge line near a mountain pass. Weather conditions change quickly at this elevation, so it helps to start early and carry layers for temperature shifts.

The Turguilla hut stands at 2,078 m south of the summit, near the path to the Réglisse lake, and has seven sleeping places on wooden platforms. The peak also overlooks the Cagateille cirque and the Guzet ski area, whose Freychet sector lies close by.
