Sandymount Strand (Irish: Dumhach Thrá) is a large strand on the east coast of Ireland, adjacent to the village and suburb of Sandymount in Dublin. It is part of South Bull - a major component of the south side of Dublin Bay, and part of the Dublin Bay Biosphere Reserve. South Bull is a mirror to the North Bull sandbank, which grew into North Bull Island.
Sandymount Strand is a popular place for locals to take a walk. People, and in the past - there is no longer public vehicular access - cars, have been occasionally trapped by the incoming tide. A large inlet of water that remains even at low tide is known locally as "Cockle Lake".
This seaside suburb is located around a pleasant harbour and has a famous Martello Tower where the writer James Joyce once stayed for a week as a guest of poet Oliver St John Gogarty.
The opening scene of Joyce's Ulysses is set in this tower. It now hosts a small Joycean museum, open in summer time. Bloomsday is celebrated in Sandycove in Joyce's honour on the 16th of June every year. It is also the birthplace of Irish patriot Sir Roger Casement (1864-1916).
