Once you get past Grenoble you’ve got a choice or routes. If you head towards Lus la Croix Haute you have a drive through stunning scenery, but maybe not necessarily great access to the best sport crags. You have the Vercors up to your right, and you pass right under Mont Aiguille, but hardly a sports crag! Then you go over the Col de la Croix Haute and down past Lus la Croix Haute. If you swing left here towards the ski area La Jarjatte, it is a stunning valley, all it’s missing is a great sports crag! A nice short via ferrata though.
As you head down this valley, the Buëch, there’s a number of crags over to your right, towards Chatillon, but they take a bit of finding and you’ll need a local guide.
South of Lus you pass my village, St Julien en Beauchêne - If you want an hour’s exercise, there’s a nice little aiguille here - in the Orpierre guide. Another 10 mins south, there’s another reasonable crag at the Gorge d’Aginelles, and a couple of ViaFerrata. Neither of these are worth a big detour, but if you’re passing....
I guess the other route from Grenoble is down the N85 to Gap, but I’ve no idea what’s along that road! In between the 2 routes is the Devoluy, which is fabulous, big mountain routes, sport, skiing, cycling, the lot!
There are other crags lower down the Buëch valley, past Orpierre, but then you’re getting off route for Cëuse. There’s a load of crags up around Lyon I believe with a local guide - but we’ve yet to explore those. Have fun!
