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!

Nice place to cool off on a small pebble beach just before the bridge when it's a heatwave!

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!).

For the peace and quiet, the view, the hiking trails, the little restaurant, the magnificent Granier aux Egaux road.
