I wish It is stunning but it'll be mobbed, I suppose it's one of those must do roads though A much better and more fulfilling road is The Gorge du Verdun, this is where Clarkson raced the two skinny hippy climbers and tested the RS4, now that is worth it, hit it at the right time, around 6-7ish in the evening, and it's breathtakingly stupendous, even my, normally, speed limiting governor of a mrs, was egging me on
Hang a right at Castellane on the Route Napoleon, do the north side, which I thought was the high side, lunch or dinner at Moustier San Marie, then take on the south side You can even do it en route to Stelvio, albeit a longer route, with a quick stopover In Monte Carlo.
I guarantee absolute satisfaction, or I'll pay your fuel bill
