Dalkey Island and the Muglins
At the southern end of Dublin Bay lie two islands about 1 km from the shore. These islands are probably two of the most dived on places in Ireland. The largest is Dalkey Island and the smaller is The Muglins. When conditions are good diving here can rival many of the best sites in the west of Ireland.
There is a wealth of marine life supported by it's nutrient rich waters. Anenomes, starfish, sponges, mussels and seaweeds adorn the rocks, while Pollack, Wrasse, conger, ling, etc. swim in the immediate vacinity. Crabs, lobsters and octopus hide in their rocky crevices.
