Best Beaches Near Dublin: Strands, Swims & Coastal Walks
Dublin Bay is a UNESCO Biosphere Reserve with more beaches than most visitors expect. This guide covers the best strands, swimming spots, and coastal walks within easy reach of the city, from the vast sands of Dollymount to the dramatic cliffs of Howth and the sheltered coves of Dún Laoghaire.
Dublin Bay stretches from Howth Head in the north to Killiney Hill in the south, threading together a surprisingly varied coastline of sandy strands, sheltered coves, Victorian piers, and dramatic clifftops. All of it is accessible by DART, bus, or a short drive, making a beach day one of the easiest and most rewarding things you can do here. For a broader look at what else the coast offers, see our day trips from Dublin guide. If you want to plan the rest of your time in the city around the water, our one-week Dublin itinerary builds in coastal stops alongside the main city sights.
💡 Local tip
Dublin's official bathing season runs 1 June to 15 September, when lifeguards are most likely to be on duty. Sea temperatures range from roughly 10–16°C year-round. Check tide times and water quality flags at Beaches.ie before you go.
Sandy Strands Close to the City
The closest beaches to central Dublin sit within Dún Laoghaire and the northside bay, reachable in under 30 minutes from the city centre. These are the go-to spots for Dubliners on a warm afternoon, and for good reason: the two main strands are long, free, and well-served by public transport.
1. Walk or Swim at Dollymount Strand on Bull Island
Dublin's closest large beach, just 5 km from the city centre. The 5 km sandy strand sits on a UNESCO Biosphere Reserve island with dunes, salt marshes, and birdlife. Take the 130 bus or cycle the wooden bridge. Strong tides, so check flags before swimming.

2. Stroll the Tidal Flats of Sandymount Strand
A vast tidal strand on Dublin's southside, immortalised in Joyce's Ulysses. At low tide, the sand stretches hundreds of metres, with views of the Poolbeg chimneys and Wicklow Mountains. It's a walker's beach rather than a swimmer's, due to the shallow tidal nature.

3. Take the Classic Pier Walk at Dún Laoghaire

What is the closest beach to Dublin city centre?
Dollymount Strand on Bull Island is the closest large sandy beach, approximately 5–6 km from the city centre. It is reachable by the 130 bus from the city or by bicycle across the wooden causeway. Sandymount Strand is also close and accessible by bus or about a 25-minute walk from Lansdowne Road DART station.
Can you reach Dublin beaches by public transport?
Yes. The DART coastal rail line connects the city centre to Sandycove & Glasthule, Dún Laoghaire, Killiney, and Howth. Dollymount and Sandymount are served by Dublin Bus routes. Fares on the DART with a Leap Card are typically under €3 one way for short coastal trips. Check Transport for Ireland for current timetables and fares.
Is it safe to swim at Dublin beaches?
Most designated Dublin beaches have lifeguards on duty during the official bathing season (1 June to 15 September). Water quality and safety flags are updated daily at Beaches.ie. Strong tidal currents exist at Dollymount's seaward side, and Sandymount is primarily a walking beach due to shallow, fast-moving tides. The Forty Foot at Sandycove and Seapoint are the most popular dedicated swimming spots.
Which Dublin beach is best for families with children?
Dollymount Strand is wide, sandy, and backed by dunes that children enjoy exploring. Dún Laoghaire's pier and nearby Seapoint offer calmer waters. Sandycove's sheltered cove is good for smaller children. All are free to access. Check Beaches.ie for current water quality status before visiting with young children.
Are there any beaches reachable from Dublin as a day trip beyond the city?
Yes. Killiney beach (mainly pebble, good for walks) is at the southern end of the DART line. Further out, Brittas Bay in County Wicklow is one of Ireland's finest sandy beaches, approximately 1 hour south of Dublin by car. Portmarnock and Rush beaches are accessible by rail or bus north of the city. These make excellent day trips; see our day trips from Dublin guide for more.
