Great straight in soft gravel. The route remains pleasant with views of the Chartreuse while staying on the flat.

Nice flat gravel path to avoid the very busy road between St Laurent du Pont and St Joseph de rivière, up to the Demay bridge. Runs along the l'Herretang canal

The most direct passage to leave Grenoble by the South following the Drac Decathlon Comboire is just to the south

It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

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

Very pretty, but it's not the Vercors, it's the Chartreuse, Mont St Eynard to be exact.
