First inhabited by the tribes of Ouen Island, it was then used to house employees of the Prony prison camp who came here to raise livestock and grow vegetables. Located near the Prony Needle and accessible by boat from Baie de la Somme, the island has an exceptional biodiversity: more than 80% of its plants are native species.

    Named after Admiral Casy in 1854, the island is a magnificent nature reserve spanning 40 hectares. First inhabited by the tribes of Ouen Island, it was then used to house employees of the Prony prison camp who came here to raise livestock and grow vegetables. Located near the Prony Needle and accessible by boat from Baie de la Somme, the island has an exceptional biodiversity: more than 80% of its plants are native species. An hour-long walk along a signposted trail is a great way to enjoy the variety of species this now unoccupied island has to offer. You can also go snorkelling to admire the coral and fish, or camp here for the night.

    Casy is a “sustainable resource management area” and as such, visitor activities are strictly regulated:
    - the removal of any animals, plants or minerals is strictly prohibited;
    - fires are only permitted if you bring your own wood and a portable barbecue;
