I went there to take a dip but the site was littered with rubbish (cake wrappers, chips, candy, tissues, McDonald's bags, pizza boxes, etc.) right down to the water. Exceptional because it was the day after the music festival or just a habit? Sunday was also packed with people (obviously)

Of this important 9th century abbey, all that remains today is the very beautiful abbey church, a priory and the gardens.

Peaceful little port on the Acheneau River. The place seems very popular with anglers.

At the end of winter, the path stops with the level of the lake which cuts the road and does not allow you to go to the end. But it doesn't matter, it's always nice to go for a little walk
