This 17.5 km circuit will take you along the Sienna harbor, with its incredible flora and fauna. The salt meadows, the samphire, the narrow streets and lanes are just some of the treasures to be discovered during your walk. You’ll also have the pleasure of hiking with a view of the harbor at Regnéville Sur Mer and the Pointe d’Agon in the distance. Soak up the atmosphere of this small commune where the maritime past is still very much alive.
