Tips from the Community

Siro Arias Valdés - Testadicorsa

A heavenly place to enjoy the Pyrenees in their full glory. Ideal for a family picnic in spring or summer. Also, as there is a bar - restaurant, it is ideal if you want to have a drink on the terrace.

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.

It is a MUST of the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Any of its slopes 2 is spectacular and tough. The views from its summit are wonderful, feeling the wild side of the Pyrenees. Of course, once at the summit of this pass... you have to descend to the Étang de Lers and enjoy a quiet rest on the shores of the lake. It is a pass that has been part of the Tour de France route on several occasions, although always far from the finish line. The first professional rider to crest it in the lead was the unforgettable Marco Pantani in 1995.

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.

I loved the climb, a little less the descent, quite tiring

I liked the climb from the north side (from Massat), very scenic and alpine landscapes towards the end at the étang de Lers

Nice steady and scenic climb to its summit. Good coffee at the arrival (with a view!)
