It’s a long trip, but Italy is fairly easy to reach via road, with connections from all border countries in the North. Taking the Eurostar to France and working from there is the quickest route, and a number of ferry routes are available for those less willing to drive across half of mainland Europe. Eurolines operating out of London’s Victoria Coach Station offer routes to a number of Italian destinations.

A standard pink EU driving license is the required driving documentation. If a photo licence is not held, an International Driving Permit must be obtained along with suitable photo ID. Insurance is mandatory and Green Card insurance is recommended.
