Berck - Route Départementale 303

Carrefour Parking: Overnight parking is permitted in the summer by the store (we asked), despite the prohibition signs. The day we were there, there were 25/30 RVs. Very convenient when there's no more space in the RV parks or to avoid paying exorbitant parking prices. Located about a 45-minute walk from Authie Bay, a better place to see seals than the Bay of Somme. There's a lot of traffic and noise at night, but it's still bearable.
