Nice hotel in Culoz. We stayed there on our long-distance hike from Tarifa (Spain) to Switzerland and can highly recommend the accommodation.

Small lake a stone's throw from the Rhône, the wine-growing villages of Bugey de Belley and Grand Colombier. You can swim there in summer at the beach on the south side or fish. To discover at the edge of the lake: its sculpted rocks and sculptures.

Lake Barterand was an interesting place of experimentation to promote the art of stone cutting. A giant sculpture was created in homage to the legends of Bugey and in particular here in Gargantua, on one side of the lake. This work first required cutting the rock in order to remove part of the hard limestone. Subsequently, 7 sculptors from all over France came together to create this work in bas relief where we find: Gargantua the giant man and gourmet who opens the rock with his powerful hands. The bunches of grapes are a nod to Bugey wines and the spirit of Bugey conviviality. It then transforms into drops then into a stream bathing the Vouivre, a half-charming, half-evil character, coming from the mists of the marsh.
