The climb from Jongieux le Haut is still very pleasant, and at the chapel you are rewarded with a beautiful panoramic view. The descent to Yenn can be very slippery in rainy weather; a warning sign is posted along the descent.

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.
