Route
Trev
Favourite for speed - Calais - Reims - Metz - Strasbourg - Mulhouse - Basle - Lucerne - St Gotthard - Chiasso - Milan - Garda - hard on the pocket though.
Favourite for cost - Calais - Dunkerque - Ostend - Brussels - Luxembourg - Metz - Chateau Salins - Phalsbourg - A4 motorway for one junction - Saverne - Molsheim - Obernai - Colmar - Basle - Chiasso and then toll free to Bergamo, A4 moorway to Brescia and then toll free again on the SS11 to Garda.
Alernative for low cost - as option 2 above to Metz, then Nancy, Charmes, Epinal, Thann, Basle and as above.
