Rockabill is a renowned offshore fishing ground and marine landmark located approximately four miles (6.5 km) northeast of Skerries in County Dublin. The area is dominated by the Rockabill Lighthouse, which stands over eighty feet tall on Carrig da Bheola, also known as Two Lips Rock. This is a classic Irish Sea mixed-ground mark, featuring rocky reefs around the base of the rock itself transitioning to sandy and mixed ground to the north near St. Patrick's Island. Depths around the lighthouse range from 7 to 9 fathoms (12.8 to 16.5 meters), while the grounds north of St. Patrick's Island drop to around 10 fathoms (18.3 meters). The area is a prime destination for small boat anglers launching from several harbours along the North Dublin coast, offering a diverse range of species throughout the year. The waters are also part of an important marine ecosystem, supporting significant seabird colonies.
