Known as L'Estanh de l'Airòla in Occitan, Étang de l'Ayrolle is a surface of lagoon water on the Mediterranean coast in the Aude department, between Étang de Bages-Sigean and the sea. Mainly located in the towns of Gruissan and Peyriac-de-Mer, the pond is included in the perimeter of the Narbonnaise Regional Nature Park. The northern part of Étang de l'Ayrolle houses salt marshes exploited at the discretion of craftsmen who sell very little of their production.
