North Bull Island

A 5-km-long (3-mile-long) island created in the 19th century by the action of the tides, North Bull Island is one of Dublin's wilder places—it's a nature conservancy with a vast beach and dunes that attract thoUSAnds of varied seabirds year-round. The island is linked to the mainland via a wooden causeway that leads to Bull Wall, a 1½-km (1-mile) walkway that stretches as far as the North Bull Lighthouse. The island is also accessible via a second, northerly causeway, which takes you to Dollymount Strand. (The two routes of entry don't meet at any point on the island.) You can reach this causeway from the mainland via James Larkin Road.
