La Baie de Sienne

The Bay of Siena offers wonderful walks between land and sea. This registered natural site covers an area of 2,061 hectares on the land domain and 42 hectares on the sea domain and extends from Montmartin-sur-Mer to Agon-Coutainville.
Taking the GR223 from Agon allows an intimate discovery of the bay, with its landscapes changing with the rhythm of the tides.
