Ran across an article in Bloomberg News:
Swiss Boaters Fight Billionaires for Lakeside Access about the struggle to gain access to lake shores, especially in the Leman region, where rich owners zealously guard their lakeside properties. Similar article (thanks, Google

) in SwissInfo a few months ago:
Campaigners want public access to all waterways.
The organization behind the campaign is
Rives Publiques, which seems somewhat similar to the
Right to Roam campaign of the Ramblers Association.
