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.
