The menhir stands on a rock called the Tombeau du Diable, which itself covers the Trou du Diable. The rock is said to be the one where Saint-Michel confronted and defeated the Devil. According to legend, a treasure was buried at its foot by a child or a salt worker after having stolen it from the Korrigans cave, on the wild coast of Pouliguen. Until the 1870s-80s, tradition dictated that young girls from the village would come to consult this menhir around August 15. Through rounds and songs around the Long Stone, they asked for their projects to come true, including marriage. If by misfortune one of the dancers touched the stone, she would not get married within the year

Bike barge only really runs on weekends in June. Don’t get caught out like I did and have to ride all the way round/through the salt marshes in the evening wind and rain.
