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!

Beautiful spot on the greenway: in addition they left the toilets functional with toilet paper, and also a drinking water point: perfect!

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!
