Detailed maps of Europe, including Western Europe, are available to view at ViaMichelin.co.uk and Europe-Map.org. The type of map detail required influences which map is the best to view online.
The Michelin map is designed for use in planning road travel and includes road numbers, junction details, markers for service stations and other useful tourist highlights. Simply drag the map to focus on the desired portion of Europe, and scroll in to see the details of local roads and connections. Europe-Map.org offers a map overlay on satellite photography that allows users to see details of the local environment rather than just the road systems.
