Dollymount Strand is the closest large beach to Dublin city centre. It is situated on Bull Island which was created in the 19th century in Dublin Bay to deal with silting problems. The sandy beach here runs along the full 5 kilometre length of the island. Today, it is an important nature reserve, being a breeding site for many bird species and one of the most protected areas in Ireland. The island, reached across a causeway from the mainland, also has two golf courses and a number of car parks. At the far south-western end, a large car park offers direct access to the beach and public toilets can be found at Bull Wall Swim Point. Another large car park can be found by the centre of the beach, also offering direct access.
