"Dublin bay" is defined by land masses in the shape of a large C, forming an immense "ring of bay and skyline." At the extreme northeastern reach of this arc lies the large, high, and wild peninsula called Howth Head (pronounced "Hoath"). Off the southerneastern tip of the C, perhaps six miles away from Howth as the gull flies, lies small Dalkey Island and the rocks around it.
