An island located in Dublin Bay in Ireland, about 5km long and 800 m wide, lying roughly parallel to the shore off Clontarf, Dollymount, Raheny, Kilbarrack, and facing Sutton.
The island is connected to the mainland by the Bull Bridge, today a one-lane wooden road bridge (with weight and height restrictions) at the southern (Clontarf/Dollymount) end, and by a broad causeway at Raheny, approximately halfway along, and forms part of Raheny and Clontarf districts.
