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.

Superb view of Hautecombe Abbey. This was built in the 12th century. It houses the remains of several kings and queens (of Sardagina, Italy) and many counts of Savoy.
