These Belledonne balconies are superb. I'd never ridden them. Who knows why 😳? From Uriage to Theys, it's absolutely beautiful, but the continuation to Allevard via the Col du Barioz isn't, in my opinion, very interesting. Next time I'll stop in Theys. Similarly, for the return, next time I'll do better because the departmental road to Grenoble is mediocre. But I was very hot and in a hurry to get home, so I didn't push myself too hard to optimize the route. All my cycling friends prefer to ride these balconies from north to south, so I'll try it next time.
