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!

The Col du Tourmalet... a pass that was a real challenge for me! It climbs continuously for 20 km without any real respite... With the end getting a bit tougher, especially mentally!

A beautiful, quiet pass. Easily accessible by mountain bike from Bederet. The trail from here to Cauterets is a dream. A must-do if you're in the area!
