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 cove of Mancel includes an island, the island of Mancel. The villages of Mousterian and Montsarrac are located on either side of the cove. It is almost completely emerged at low tide and totally submerged during high tides. It is rich in eelgrass which attract waterfowl, such as geese, shelducks, swans and egrets. The sacred ibis is also common there since its accidental introduction into the gulf.
