The cols here are all world famous, thanks to the rather well known road race, the Tour de France.

Col de l'Iseran 

This col is one of the most famous and challenging road bike climbs in the French Alps. At 2,764m, it is the highest paved mountain pass in the Alps, making it a legendary route for cyclists. It often features as part of a stage in the Tour de France, adding to its prestige among road cycling enthusiasts.

The climb can be tackled from either the northern or southern side.

From Bourg-Saint-Maurice (north)

Distance: ~48km
Elevation gain: ~1,955m
Average gradient: 4.1% (but steeper in sections)

Key features:

  • a long but steady climb with breathtaking views
  • passes through Val d’Isère, a famous ski resort
  • some tunnels and avalanche protection structures
  • the final stretch is exposed and can be affected by wind

From Bonneval-sur-Arc (south)

Distance: ~13.4km
Elevation gain: ~977m
Average gradient: 7.3%

Key features:

  • shorter but steeper and more intense climb
  • stunning high-mountain scenery with hairpin bends
  • less traffic than the northern approach

It’s an epic challenge but well worth the effort for those who love high-mountain cycling.
