I plan a trip for late spring: I will start from Feldkirchen at the Austrian border, crossing Switzerland to reach the Aosta valley in Italy, drive to the Montblanc area than down to Nizza and back to Italy's Riviera, to Genua than Livorno where I will load the M3W on a train to Vienna.
Did a similar tour with the motorbike some years ago and it was great.
Now I hope for nice weather in June.
