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…).

When to go to Bird and Denis Islands?

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.

Snorkeling is possible all the year round, with average water temperatures of 82°F/28°C. From October to March, rains are more frequent (with a peak in January), the temperatures are highest (+/-86°F/30°C) and there is most humidity. From April to September there is a cooler and dryer period, but it is also windier (+/-75°F/24°C). As the wind has a certain amount of importance in snorkeling, you should remember that the prevailing wind is north-westerly from October to March and south-easterly from April to September. The inter-seasons (March to May and September to November) are the best periods for snorkeling.
