Ireland's Eye Anciently called 'Adros' by Ptolomy, 'Adrea Deserta' by Pliny, and 'Andros' and 'Edria' by other early navigators. is a small long-uninhabited island off the coast of County Dublin, Ireland. Situated directly north of Howth village and harbour, the island is easily reached by regular seasonal tourist boats, which both circumnavigate it and drop off day trippers. There is a yacht anchorage to the north of it, and kayakers also land.
The island is formed from quartzite and greywackes, and some sandstone, and has soils based on glacial drift. It is home to nationally significant bird populations, notably of guillemots, razorbills, kittiwakes and cormorants, as well as gulls, and also including modest numbers of puffins and peregrine falcons.
