Very poorly maintained road (stones, dung, etc.) but without any cars. A good alternative for a quiet climb, definitely to be avoided on the descent.

The road is reserved for bicycles and pedestrians, it's really pleasant, especially with everything else being full of cars... it's a nice break, plus the view is magnificent, we really appreciate it!

No cars, no motorcycles. This section of the Tourmalet is very pleasant. The surface is a little rough, but passable.

Reaching the Col d'Aubisque from Argelès-Gazost is a real journey. To get there, you have to overcome nearly 30 kilometers at an average gradient of 4.7%. The climb is irregular, with two respites: one just before starting the climb to the Col de Soulor, around the tenth kilometer; and a second at the twentieth kilometer, after switching to the other side of this same pass.

Uncleaned road, lots of stones and gravel + dirt. Possibly take it on the way up if you are fed up with cars on the main road, but otherwise stay on the main road. On the way down, there is no question: don't take this road!
