Pic de Séron

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.

This summit has served as a natural boundary marker between communities in the Ariège for centuries, shaping the territorial divisions of the region. Its role as a dividing point between territories established a lasting geographic and administrative legacy.

Local shepherds have grazed their flocks on the slopes for many generations, and you can still see the pastoral practices that shape the landscape today. This heritage of herding connects the peak to the communities below.

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.

Three mountain lakes - Aubé, Réglisse, and Astoue - are positioned around the summit in an equidistant pattern that creates a distinctive triangular arrangement. This unusual geographical configuration makes the area memorable for visitors exploring the mountain terrain.
