Like the numerous marshes that embroider the interior of the Gulf of Morbihan, the Lasné marsh maintains a rich animal diversity. Every year, thousands of birds come to feed and nest in its waters. When walking, be discreet and equip yourself with a binocular to observe them.

The tip of Corn Er Vechen is a tiny projection of land in the Gulf of Morbihan. On clear days, the views are clear and water activities multiply. Ideal for a little quiet break.
