Ferries to Italy

Ciao Bigmal,
well to get across the Channel you will need to look up the sites of P&O, Seafrance, Norfolk line, and Eurotunnel.
Once you get to the other side, Calais or Dunkirk, then suggest for starters what is known as the 'Russell Route'. This has been my personal favourite for many years:
Calais or Dunkirk, toll free A26 to Lille, from there toll free in to Belgium towards Mons/Charleroi/Namur. At Namur turn right for toll free to Arlon/Luxembourg. Across Luxembourg, with a stop here for cheap fuel, in the direction of Thionville/Metz. At Metz go towards Strasbourg, here a small toll is paybale. Then Strasbourg - St.Louis - Basel in to Switzerland. At Basel pick up Swiss vignette for motorways, Euro 40, and proceed to Luzern/St.Gothard Tunnel (included in your vignette). Through St.Gothard to Airolo/Bellinzona/Chiasso, and enter the Italian toll road system at Como.
Another route, if you have time, is Calais - Reims - St. Dizier - Epinal - Col
du Bonhomme - Mulhouse - Basel, and then as above.
Many more routes available, but less direct.
For aires/campsites then I would consult the MHF data base in the first instance.
Once in Italy then you can go East towards the Adriatic, where most of the 'bucket and spade' sandy beaches are to be found. e.g. Lido di Jesolo, Lignano Sabbia d'Oro, or a bit further South to Rimini/Cattolica/Riccione.
On the Tirrenian West Coast, you would need to get down as far as the Tuscan riviera to find wide sandy beaches, such as Forte dei Marmi, Lido di Camaiore, Marina di Pietrasanta.
In all the above mentioned areas, most beaches are 'private' in that they have been given a goverment concession to be able to provide access/deckchairs/bars etc. for a fee. Usually somewhere around Euro 10 per person per day, although iit can vary widely. In each area you will find however also public no charge beaches. You will be hard pushed to find any wild camping areas though.
