Clémencières Pass

Highlight • Mountain Pass

A wonderful little pass just outside Grenoble. The climb via the Narbonne road is definitely worth the detour. It's steeper than the traditional route, but so peaceful!

The Col …

Pfff, the climb to the Col du Coq was tough... It's still just as beautiful but to be done in the morning, not on a Sunday evening after all the good weekend meals!
Otherwise, a great scare in the first bend on the descent after the Col de Porte: probably the film of diesel after the rain which made me …

But the circuit is still …
