Small pass in the Chartreuse, beautiful views and relatively quiet road.

The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible

From Saint Laurent du Pont, a demanding 14km climb, with many sections at over 10%. It is divided into three parts: 9km of irregular ascent (6 to 11.5% /100m) to the junction for the Chartreuse Monastery. Then 2km of flat terrain to the foot of St Pierre de Chartreuse and finally a very steep climb (several sections at +12% /100m) to the Col de Cucheron. A pass not to be underestimated! 25 degrees at St Laurent = 15 degrees at the top of the pass and its very shaded slopes. Dress accordingly.
