ASDU is famous for its live house reef jealously guarded and protected by it's management.

The natural beauty of this tiny island is in its white sandy beach that recedes to crystal clear waters of the lagoon and in its exotic coral reef abundant in tropical fish of unimaginable colours. The fish literally swim with you and occasionaly nudge you for new acquaintance. The reef, about 20 to 30 meters from the beach, is ideal for beginner-divers and for snorkeling. For the experienced diver there are the special off-shore reef diving spots as well as the channels that open to the Indian Ocean to have a rare glimpse of what life is with the undersea predators.
