How to Get to Dalkey

Dalkey is a coastal suburb of Dublin with frequent DART rail service and easy access from Dublin Airport. The DART is usually the fastest, most reliable way to reach central Dublin from Dalkey.

By Air

Dublin Airport (DUB): Dalkey is best reached via Dublin Airport (about 20-30 km; 25-40 minutes by car). From the airport you can take an Airlink/Aircoach bus into Dublin city centre (≈€7-10) then transfer to DART suburban rail from central Dublin to Dalkey (see train paragraph). Taxi direct to Dalkey is about €30-45 and takes around 25-40 minutes depending on traffic.

Shannon / other airports: Farther away and not practical for Dalkey unless combining other travel plans.

By Train & Bus

Train: Dalkey is served by the DART (Dublin Area Rapid Transit) on the coastal line - the station is Dalkey station. DART runs every 10-20 minutes in daytime to central Dublin (Connolly/Grand Canal Dock) and to Bray/Greystones; journey to central Dublin is ~20-30 minutes. Typical single fares are around €2.50-€4.50 depending on card/zone and discounts.

Bus: Dublin Bus routes and local private operators serve the area for short hops and connections; buses can be useful for places outside the DART corridor but are slower for city centre access.

How to Get Around Dalkey #

Dalkey village is very walkable, with a compact centre of cafés, shops and pubs. The DART rail line stops at Dalkey station, providing fast and frequent trains to central Dublin and south towards Bray; several bus routes and taxi services also serve the village. Cycling is an option for short trips along the coast, and a car is useful for exploring nearby coastal walks and estates.
