Salt Marshes of Île d'Olonne
Highlight • Natural
From June to September, during the harvest period, the salt workers are on the site of the salt marshes.
'Discussed walks' allow you to follow a salt worker for around 1 hour and discuss the marsh, the profession and all the subjects linked to this activity (context, environment, economy).
