The center of Foix is small but very cute. It's worth taking a walk through the historic center.

I climbed it from its easier side, the one that starts from Foix and stretches for 28 kms, crossing the Col de Marrous. It's a steady climb, with a few tough kilometers, and very pleasant. It's the side used by the Tour de France to descend it. The best thing about the Mur de Peguère are the views from its summit.
