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.

The road is a bit chilly in winter, near the start of the climb to Cachaudegé and the Portech pass.

Be careful, since yesterday, June 19th, the descent to Rivèrenert has been freshly graveled and dangerous. I had a rear puncture due to small, sharp gravel sticking to the tire when braking. So, don't go crazy on this descent, friends.

Because around 12pm and >31°C, the climb from Biert is mostly in the shade, and this pass generally ends a series of small linked passes (like Portech, Catchaudégué or La Core, Saraillé, etc.). And the challenge of the last 3 km is worth experiencing to strengthen your mental strength. Get to your pedals

Beautiful place in the Pyrenees surrounded by mountains with a thermal bath from 1822. The Marathon des Oussailles starts here.

Couserans is a Gascon country of mountains, hills, meadows, lakes, waterfalls and forests which is entirely part of the Pyrénées Ariégeoises Regional Natural Park. Among its 18 valleys located at the foot of the majestic Mount Valier, some remained landlocked until the recent past, which allowed them to maintain their own identity, such as the Bethmale valley. At the beginning of the 20th century, it was an overpopulated country whose small agricultural plots did not allow families to live, which is why the inhabitants had to show a lot of imagination to find survival activities. This is how some became “bear handlers”, peddlers of vanilla, fake stone, ice. Others became itinerant “raw distillers” or gold prospectors.
