Getting to Dublin

By Air: Dublin Airport

Dublin Airport (DUB) is the main international gateway to Ireland and one of the busiest airports in Europe. It has two passenger terminals: Terminal 1 (older, handling a mix of airlines including Aer Lingus short-haul and most non-Ryanair carriers) and Terminal 2 (newer, handling Aer Lingus long-haul routes and some others). Most airlines are clearly signposted, but check your terminal before you arrive to avoid a long walk between buildings.

The airport is about 12 kilometres north of the city centre. Journey time to the city varies between 25 minutes (off-peak by car or bus) and over an hour in heavy traffic. Morning and evening rush hours can significantly extend road journey times. Plan accordingly.

Airlines serving Dublin: Ryanair and Aer Lingus dominate, with between them operating routes to most European cities. Long-haul routes connect Dublin directly to North America (Aer Lingus, United, Delta, American Airlines), the Middle East (Emirates, Etihad), and a growing number of other destinations. The US pre-clearance facility at Dublin Airport means American-bound passengers clear US customs and immigration before boarding, avoiding the process on arrival in the States.

Getting from Dublin Airport to the City Centre

There are four main options for getting from the airport to central Dublin: bus, taxi, private transfer, or car hire. There is no rail link (a proposed Metro North connection has been planned and cancelled multiple times over the decades). Here's the honest breakdown of each.

Aircoach is a comfortable express coach service running from both terminals to multiple stops in the city centre, including O'Connell Street, College Green, and several stops south to Ballsbridge, Donnybrook, and onwards to Bray. Services run 24 hours a day, 7 days a week, approximately every 15-30 minutes. Journey time is typically 30-45 minutes but can stretch to an hour in heavy traffic. Tickets can be bought on the bus (card payment accepted) or cheaper in advance online at aircoach.ie. A single adult fare is approximately €8-12 depending on route.

Dublin Bus Airlink (routes 747 and 757) is the lower-cost bus option, operated by Dublin Bus. Route 747 connects both terminals to Busaras (the central bus station), Connolly Station, O'Connell Street, and the south inner city. Route 757 serves a different set of south city stops. Leap Cards are accepted and provide cheaper fares than cash. Airlink is good value but can be slower than Aircoach in heavy traffic and luggage space at rush hour is limited.

Taxis are available from the official taxi rank outside arrivals in both terminals. A metered fare to the city centre costs approximately €25-35 depending on destination and traffic. There's no need to haggle or agree a price in advance; the meter is the fare. FreeNow and Uber also work from the airport for pre-booked pickups, but the official rank is straightforward and there's no advantage to apps over walking to the rank. Allow more for peak traffic times.

For private transfers, several companies offer pre-booked door-to-door transfer services from the airport to your hotel or accommodation. These are priced higher than taxis but offer the convenience of a named driver meeting you in arrivals with your name on a board. Useful if you're arriving very early or late, with a large group, or simply don't want to faff about with the rank. Dublin Airport private transfer bookings on GetYourGuide cover the main transfer operators with clear pricing. Airport transfer options on Viator include private and shared shuttle services at various price points.

Car hire desks are in both terminals. All the major operators are represented (Hertz, Europcar, Enterprise, Sixt, Budget, Avis). Ireland drives on the left. Rental cars are almost always manual transmission unless you specifically book automatic, and automatics typically cost significantly more. If you're planning to spend time in Dublin city centre, think hard before picking up a car at the airport: parking in the city is expensive, traffic is challenging, and the public transport options are sufficient for most itineraries. If you're heading straight to other parts of Ireland, collecting at the airport makes sense.

By Ferry: From Britain and Europe

Dublin has two ferry terminals: Dublin Port (about 3km east of the city centre, on the north bank of the Liffey) and Dun Laoghaire harbour (about 15km south of the city centre, on the coast).

Irish Ferries and Stena Line are the main operators from Holyhead in Wales to Dublin Port. The crossing takes about 3.5 hours on the fast craft service and about 3.15 hours on the conventional crossing (timings vary). Both companies also operate overnight services with cabin accommodation. From Holyhead, rail connections from London Euston and across Wales make this a viable car-free option for travellers from Britain who prefer not to fly. Journey time London to Dublin via Holyhead is approximately 8-10 hours total.

P&O Ferries operate from Liverpool to Dublin Port, a longer crossing (about 8 hours) but useful for travellers from northern England and Scotland. Brittany Ferries connects Roscoff in Brittany and Cherbourg in Normandy to Cork (not Dublin), which is worth knowing if you're arriving from France and planning to travel north.

Getting from Dublin Port to the city centre: buses run from outside the terminal to Busaras and O'Connell Street, or a taxi is about €12-15. The walk to the city centre from Dublin Port is about 40 minutes along the North Wall Quay, which is doable in good weather with not too much luggage.

Getting from Dun Laoghaire to the city centre: the DART train from Dun Laoghaire station (a 10-minute walk from the ferry terminal) takes about 20 minutes to Pearse Street or Connolly Station. This is actually one of the more pleasant ways to arrive in Dublin, on a clear day the DART runs along the coast with excellent views of the bay.

By Rail: From Within Ireland

Dublin is the hub of the Irish rail network, operated by Irish Rail (Iarnrod Eireann). Intercity services connect Dublin to Cork, Galway, Limerick, Waterford, Sligo, and Belfast. Dublin has two main rail termini:

Heuston Station, on the south side of the Liffey west of the city centre, handles trains to Cork, Limerick, Galway, Westport, Tralee, and Waterford. It's served by the Luas Red Line (Heuston stop) and several bus routes. From Heuston you can reach O'Connell Street by Luas in about 10 minutes.

Connolly Station, on the north side of the Liffey near the Docklands, handles trains to Belfast, Sligo, and Wexford, as well as DART and commuter rail services. It's about a 15-minute walk from O'Connell Street or accessible by Luas Red Line.

The Enterprise train service between Dublin Connolly and Belfast Lanyon Place takes about 2 hours and is a scenic and comfortable way to travel between the two capitals.

By Coach: Intercity Buses

Several coach operators connect Dublin to cities across Ireland and to Britain. Bus Eireann is the national operator, running from Busaras (the central bus station on Store Street, north inner city) to towns and cities across the country. Private operators including GoBus, FlixBus, and various regional operators also serve major routes, often at competitive prices if booked in advance.

International coach services from Britain, operated by companies including National Express and FlixBus, connect Dublin (via ferry) to London, Manchester, and other British cities. These are cheap but very long journeys and are only worth considering if flying is genuinely not an option.

What to Know Before You Arrive

Currency: The Republic of Ireland uses the euro. Northern Ireland uses pound sterling. If your trip is entirely in the Republic (which Dublin is), you won't need sterling. Card payments are accepted almost everywhere in Dublin, including in most taxis. Cash is useful for some markets, smaller pubs, and tips, but you won't be caught out by relying on card for most things.

Power: Ireland uses Type G plugs (the three-pin UK-style plug) and 230V power. This is the same as the UK. If you're coming from continental Europe, North America, or most other regions, you'll need an adapter and possibly a converter. Most modern phone and laptop chargers are dual voltage (check for 100-240V on the charger), so you'll only need the adapter plug.

SIM cards and data: EU roaming rules mean that visitors from most EU and EEA countries can use their home mobile plans in Ireland without extra charge (check with your provider). Visitors from outside the EU should consider an Irish SIM or an eSIM from operators like Airalo for affordable data. Coverage in Dublin city centre and along the main transport routes is excellent with all Irish operators (Three, Vodafone, Eir, Tesco Mobile).

Entry requirements: Republic of Ireland is not in the Schengen Area, though it is in the EU. Citizens of EU and EEA countries can enter freely. UK citizens can enter freely under the Common Travel Area arrangement. Citizens of the US, Canada, Australia, and most other developed countries can enter visa-free for tourist visits. Check current requirements with the Irish Naturalisation and Immigration Service (inis.gov.ie) if you're unsure, as rules can change.

Time zone: Ireland is in GMT (Greenwich Mean Time) in winter and IST (Irish Standard Time, GMT+1) in summer. Clocks change in late March and late October, the same schedule as the UK and most of Europe.

Useful Apps to Download Before You Arrive

A few apps worth having on your phone before you land: TFI Live for real-time public transport tracking, FreeNow for taxis, Revolut or a fee-free card for spending in euros (if visiting from the UK), and the Dublin Bus app or just Google Maps, which handles Dublin public transport routing well. Leapcard.ie works as a mobile top-up if you run low on credit.
