Global guests, local quests: Whenever there was a full moon in the sky, the Arteplage Mobile du Jura transformed itself into a ship of discovery and undertook its full moon expeditions from midnight until the new morning. It sought out the most charming spots on the shores of the three lakes. A guide provided the passengers with food, drink and warm blankets. The adventure cruises were each characterised by a particular musical ambience (jazz, classical, baroque, psychedelic) and offered more leisurely cultural contributions (readings, films).
