You leave Brem-sur-Mer and there, suddenly, a superb marshy area that you cross for several kilometers. Very frequented by cycle tourists, these marshes are absolutely worth the detour. We will stop at the viewpoints where the marshes disappear into the horizon, populated by seabirds... An enchantment.
