How to Get to Dún Laoghaire

Dún Laoghaire is easiest to reach via Dublin - Dublin Airport (DUB) is the main international gateway, and the town is on the DART suburban rail line. From the airport you can combine an airport bus into central Dublin with a DART train, or take a taxi for door-to-door convenience.

By Air

Dublin Airport (DUB): Taxis from Dublin Airport to Dún Laoghaire take about 25-35 minutes and typically cost €35-€50. For cheaper options, take the Airlink 747/757 or other airport buses into Dublin city centre (around 30-45 minutes, about €7 one-way), then transfer to the DART suburban rail at Pearse or Connolly for a ~20-25 minute ride to Dún Laoghaire (Dún Laoghaire station).

By Train & Bus

Key interchange stations are Dublin Connolly and Pearse; the DART from central Dublin to Dún Laoghaire takes roughly 20-25 minutes. Single fares on suburban rail vary by distance and payment method but typically fall in the low single-digit euro range; Leap cards give cheaper fares.
