Denis is about twice the size of Bird and lies about 95 km north of Mahé (and 45 km east of Bird). The vegetation is denser than on Bird, and with its wild and romantic ambience, Denis Island is an ideal candidate for honeymoons and honeymooners. It is shielded on the south and east sides by a protective coral reef, which creates ideal conditions for snorkellers. A lighthouse - along with some historic buildings - still remains from the days of the coconut palm plantation.
In der ehemaligen Pflanzersiedlung leben rund 50 Insulaner, die auch Vieh züchten und Gemüse anbauen, das hauptsächlich in der Küche der Inselunterkunft Verwendung findet.
