A magnificent location offering stunning views of the Ariège Pyrenees: the Montcalm Massif, the Bassiès Massif, the Beille Plateau, and more. Easily accessible from Croquié in both summer and winter, provided you're well-equipped and at least a little fit (800m+). Its only drawback: it's very crowded, especially in winter.
