A superb climb which leads us to a magnificent view of the Chartreuse mountains, much more beautiful than at the summit of the Col des Mille Martyrs, and yet much less known!

The church was built between 1902 and 1911. The use of concrete imitating stone is remarkable.

Very good for a restart, to be done regularly the first few weeks 😊

This cycle path connects Grenoble to Valence along the Isère River. It's flat, a little boring, but car-free.

1.5km for 150m of elevation gain. As soon as you leave the Col de Parménie, the gradient starts at 12%, then quickly increases to 14% and then climbs to 17%. It calms down a bit after the bend. The road is in good condition, relatively wide, and with little traffic (it's a dead end), which allows you to maneuver to cope with the slope.

Not far from Vorreppe, the Isère River flows around the Bec de l'Échaillon, which overlooks it at an altitude of 622 meters. This meander offers a magnificent view of this Vercors peak.
