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!
