Milliau Island,

A listed site owned by the Conservatoire du Littoral, Milliau Island covers an area of 23 hectares. Comprising moorland, rocks and cliffs… Over 250 plant species grow there, making it a veritable little natural paradise. It is also of great geological interest as it is composed of pink granite and is home to one of the oldest volcanic rocks. Aside from the many stories one could tell about this island, another distinctive feature is how to reach it: it can only be reached on foot at low tide.
