There are 6 sea shuttles on the Arcachon Bay, either by pinasses or by small boats. It is often possible to board a bicycle on the trans-basin. Only the sea connection between Arcachon and Cap Ferret operates all year round.
These 6 shuttles depart from Arcachon or Cap Ferret or Moulleau or Canon or Andernos les Bains or Dune du Pilat.
