September 25, 2026, Piste cyclable du tracé ferroviaire près de Foix

Beginning or end of the railway cycle path „Voie Verte“ St. Girons - Foix or vice versa. A short section also serves to continue to (or from) Palmier. The Foix - Pamier route is neither signposted nor developed. But it can be easily ridden on small side roads.

At the school, there is a tap on an outbuilding. When heading towards Foix, this is the last tap directly on the cycle path that we noticed. It makes sense to refill your supplies here.

One of many old train stations on the route, all of which are inhabited as private homes. How we wished that one of them housed a café. Nostalgic memories of the Alpe-Adria journey are awakened!

Trailhoulet du Vernajoul 10.5 kms

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.

I can only speak about my experience descending it from the south side, the one that starts in the village of Biert. It's simply a great pass, with a very tough final section, very similar to its close brother Mur de Peguère. With hardly any traffic, it has the appeal that the road is very narrow and very winding, which helps mentally.
