Rhone-Alpes (inc. Lyon) ...

Best tackled North to South so you're doing the northern hairpin section uphill. Endless hairpins at the northern end, fast open section in the middle and some nice twisties on the southern end, a great road. Only problem we had on one run was melting tarmac with 40+ temperatures.
A recommended detour instead of taking the N85 south from Grenoble.
