I love this village. It's an ideal starting point for a hike to the Cirque de Saint-Même.

The ASTERIX comic series by the author duo Goscinny & Uderzo, which has enjoyed success far beyond France's borders, has introduced its international audience to the unexpected characters that appear here. The distinctive style with which the various inhabitants of the famous Gallic village are drawn makes each character unique.

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

Beautiful surroundings and a wonderful place to start this (and other) hikes. Les Ateliers du Cucheron is a fantastic hotel/gite with very friendly staff. I'll definitely be back to discover more hikes.

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.

A little "kick in the pants" to get out! Cool and in the shade!
