Superb climb! The beginning is the hardest, with very high gradients. Then it gets less steep, and the landscape opens out into a superb high valley, and the views get better and better as you go along. Beware of the few very narrow tunnels, where passing each other is difficult and a headlamp is essential! There is little traffic as the valley dead-ends at the summit.... read more

Superbe ascension ! Le début est le plus dur, avec des pourcentages très élevés. Puis cela devient moins raide, et le paysage s'ouvre sur un superbe vallon d altitude, et la vue devient de plus en plus belle à mesure qu'on progresse. Attention aux quelques tunnels très étroits, où se croiser est difficile et une lampe indispensable ! Peu de trafic car la vallée est en cul de sac au sommet

Very gentle climb, which after a tough start flattens out into a long valley through beautiful (unlit) tunnels, where large holes in the wall give you nice views (and some light)!

Zeer rustige beklimming, die na een pittige start afvlakt een lang dal in door prachtige (onverlichte) tunnels, waar je door grote gaten in de wand mooi uitzicht hebt (en wat lichtval)!
