ViaRhona is a cycle route from Geneva to the Mediterranean Sea, and this site includes an interactive map which allows visitors to search for places and features along the route, and to add their own features such as hotels, restaurants, cycle shops etc.
Each feature includes a description and an icon which allows features to be grouped together for easy reference.
Feature-creators need a valid email address and (optionally) a website from which they can link their feature.
The service is free, supported by advertising. Further work on the site will follow in the next few weeks.
