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.

A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

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 cave and at the northern exit there is even a waterfall and another picnic area (in the shade, more for summer, in winter we prefer to picnic at the southern exit!)

A place full of charm: a unique cave with the road passing under the rock: you have to go through it, and go through it again!
