Col du Grand Colombier, Mountain pass in Ain, France
Col du Grand Colombier is a mountain pass in the southern Jura hills reached by a completely paved road with four different climbing routes. The road connects various valleys and offers different difficulty levels depending on the route chosen.
The pass was long ignored by the Tour de France until the race included it for the first time in 2012. This inclusion marked an important moment for the region and brought international recognition to the pass.
The pass draws cyclists who gather to tackle steep climbs together and become part of the local mountain cycling tradition. For many visitors, riding over it becomes a personal challenge within this mountain landscape.
Visitors should be prepared for changing weather conditions, as the mountain pass can develop unexpected cold or wet conditions depending on the season. Those coming by bicycle should be in good physical condition, as the longer routes demand endurance.
The pass holds a special place in professional cycling as it lies outside the Alps and Pyrenees yet reaches the highest difficulty category in races. This exceptional status makes it particularly interesting to cyclists.
