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

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!

The coolness in these gorges is much appreciated when it's close to a heatwave on the plains! And the wild atmosphere of the small road through these gorges (before reaching a busy road for a beautiful descent) is good (a little "kick in the ass" to get out!).
