Leisure base opposite Bas Bugey. A pleasant stop, but strangely located between 2 nuclear power plants...

Beautiful little lake! Not a soul around at the start of the year. I recommend passing by if you're cycling.

Small chapel dating from 1670 near a fountain, the end of the Roman aqueduct which crosses the village of Vieu and crosses this small cliff. Very beautiful viewpoint towards the south nearby.
