Shortly before the bridge over the Canal du Rhone à Sète, you can turn onto a gravel path next to the canal. However, the entrance leads under a barrier, it is not possible to drive around. If you have luggage with you, unloading is unfortunately inevitable.
This saves you a 20km detour of EuroVélo 6 around the Étang de Vic via Villeneuve-les-Maguélone. The trip right next to the canal is extremely interesting, as the canal is structurally delimited and runs through the Étang de Vic. Although the path is a gravel / gravel road, it can also be ridden well with a loaded trekking bike
