This prominent hill rising out of the plain is the remnant of an island when the sea was much more extensive in the 2nd century BC. There must have been a priory here of the abbey in the nearby village of St. Michel de l'Herm. A small chapel now stands in a private garden. The moinerie (monks' quarters) and school are privately owned.

North of Baie de l'Aiguillon, this sandy point was once a protection for ships. A real break between the marsh and the sea, the dunes cohabit with the mudflats and salt meadows. Located in the middle of the migratory axis, the Pointe de l'Aiguillon allows you to observe more than 400,000 migratory birds each year. From April to August, be vigilant: the Kentish Plover breeds on the beach. To preserve the eggs and the broods, please walk DOWN the beach.

Beginning of the sensitive natural area protected from the Breton sluice, the strait located between the northeast coast of Île de Ré and the mainland. This strait opens to the north-west on the Atlantic Ocean off Sables-d'Olonne and ends, in its south-eastern part, by the bay of l'Aiguillon (mouth of the Sèvre Niortaise) towards the north and the Ile de Ré bridge to the south.
