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)

The largest natural plain lake and the second largest ornithological reserve in France, Lake Grand-Lieu offers magnificent lakeside landscapes. Here, you have to get off your bike to get as close as possible to its waters.
