If you get the chance go in or come out via the Mont Blanc tunnel. Fantastic!! Good French National and Departmental (our A & B roads but better) down there. Bit of M/Way but that's how it goes. Italian drivers are great??
. All get a new horn every Xmas cos they wear them out through the year. Watch out for those crazy 'anything hanging off your shoulder goes with them' putt putts. Ice Cream is nice too
. Coast road is good I used to do it in a artic so a bike is way easier. Carabinieri (national police) take no prisoners so beware. Apart from that ENJOY!!
