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.

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

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
