Bird and Denis Island are coral cays surrounded by white sand beaches. From the closed lagoons, on the eastern side of the islands, to the shallow sea grass and coral areas, on their western side, Bird and Denis offers a wide variety of marine environments. Their waters are home to outstanding marine life: hawksbill sea turtles resting under the surface, inoffensive juvenile blacktip reef sharks sneaking out the rocks, spotted eagle rays darting above the seagrass, sea anemones hosting couples of skunk clownfish, and a wide variety of other species (angelfish, triggerfish, butterflyfish…).

Hawksbill sea turtles and skunk clownfish can be easily spotted while snorkeling along Denis Island’s coasts.

Bird Island and Denis Island, like the other islands of the granitic bank of the Seychelles, enjoy a tropical climate and pleasant temperatures all the year round. Unlike other groups of islands in the Seychelles (Aldabra or the Farquhar islands), they are not in the path of cyclones.
