Popular around Retenue du Dorlay
The Col de Pavezin is certainly not the highest, but it is no less mythical. The inventor of the derailleur, Paul de Vivié, who settled here, made it an unmissable rendezvous. The pass is located between the Rhône valley and the Gier valley, and opens up a grandiose panorama of the Alps and the Rhône furrow.

Very rocky, it hits your legs hard and for a long time Half sunny - half shaded A bit steep, you'll have to pedal to pick up speed In conclusion, very pleasant, but very physical when you want to set a time trial
