Bull Island lies off Dublin's city's north coast between Clontarf and Sutton. It's not really an island at all anymore because it is connected to the mainland by a road in it's middle part and also by this wonderful wooden bridge at it's most southern point. The bridge is only wide enough to accommodate one car at a time and so it is fitted with traffic lights. The bridge is also the start of the Bull Wall which was built to provide shelter for shipping in Dublin Bay. The Island has 2 golf courses, is a bird sanctuary and of course has a fabulous stretch of white sandy beach called Dollymount. Bull Island is correctly known as North Bull Island, because there is also a South Bull and if you look carefully at the photo you can see the South Bull, which forms the other half of this sea defense system. This extends from Poolbeg on the south side of the river Liffey and the Poolbeg lighthouse is visible at it's end.
