Despite the risk of becoming a sandbank, the bay of the Somme in Picardie is part of the club of the world’s most beautiful bays. The bay is also known for the presence of seals. There is a large number of campsites in well-known towns such as Le Crotoy (with nine campsites) or Quend (with seven campsites), but there is also a campsite open all year round in Larchères and a five star campsite in Villiers-sur-Authie.
