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

This is the longest tunnel on the greenway: it's super fun to go through. Be careful: it's a bit chilly!

A very beautiful viaduct, it's a bit impressive and truly unusual on a greenway. The train used to go there, now the bikes go there!

Hello everyone, I'm from Ariège, I decided this year to do the greenway with my dog Emy in both directions. It's a very beautiful walk, however there are some black points: lack of stone benches to deter potential thieves, and on the other hand the large Rimont tunnel which is 803 m long there is no more light. The motion detector does not work. Luckily that day I had my flashlight with me. There is horse excrement everywhere, perhaps one day we will have to ask the riders to pick up their droppings. It's a very beautiful walk.
