Even on an electric mountain bike in turbo mode, some sections are impassable. To get through them more or less, you have to look for the sides of the track, where a bit of grass allows you to pass without getting stuck in the sand.

The sandy trails are impassable by bike. We had to walk a lot on these trails.

From the beautiful restaurant on the Bay of Authie, a narrow footpath leads past the small harbor of Madelon - and if the water is not too high, it even takes you the three kilometers to the bridge for pedestrians, cyclists and horse riders towards the Baie de la Somme.
