Coaches are the backbone of intercity travel in Ireland, and for good reason: they connect every major city and most large towns at reasonable fares, they run frequently between Dublin and the other population centres, and — unlike the train network — they reach coastal towns and rural hubs that the railway simply never served. Understanding the four main operators and how their routes overlap will save you both money and waiting time.
Bus Éireann: the national network
Bus Éireann is the state-owned national coach operator, running Expressway services between most Irish cities and towns. Its network is the widest of any Irish operator, covering routes from Dublin to Cork, Galway, Limerick, Waterford, Sligo and further north to Derry. It also operates into Northern Ireland on some cross-border routes, though Translink (the Northern Irish operator) handles most services within Northern Ireland itself.
Expressway coaches are comfortable and modern, with luggage holds and USB charging on many vehicles. Tickets can be booked online at the Bus Éireann website or via the Leap card system for certain city services. Fares on popular long-distance routes are competitive, and booking in advance usually secures the lowest price — walk-up fares cost more on busy routes.
Bus Éireann also runs Local Link services in rural areas, though these are more relevant to local residents than to travellers moving between cities.
Citylink: the fastest Dublin–Galway option
Citylink is a private operator that specialises in express services between Dublin and the west of Ireland, with routes to Galway, Athlone, Westport, Clifden and Limerick among others. On the Dublin to Galway corridor — one of Ireland's busiest intercity routes — Citylink and Bus Éireann compete directly, and the competition is good for passengers: frequent departures, keen fares and modern vehicles.
Citylink coaches typically run non-stop or near-non-stop between major stops, making them faster than some equivalent Bus Éireann journeys. Dublin to Galway takes around 2 hours 15 minutes to 2 hours 30 minutes depending on the service. Citylink departs Dublin from outside Busáras (the central bus station) on Store Street, making coordination with other services straightforward.
GoBus: competing on the Galway corridor
GoBus also operates on the Dublin–Galway corridor and overlaps with both Bus Éireann and Citylink on that route. Like Citylink, it focuses on frequency and competitive pricing rather than breadth of network. For the Galway route in particular, comparing all three operators when you book — Bus Éireann, Citylink and GoBus — can turn up a meaningfully cheaper or more conveniently timed departure. GoBus also runs to Ennis in County Clare and some Connacht towns.
All three operators depart from the Dublin city centre area, though the exact stop may vary slightly — check your specific booking for the boarding point.
Aircoach: airports and express city links
Aircoach is a private operator that focuses specifically on airport connections and a small number of express city-to-city routes. Its primary use for most travellers is the Dublin Airport to Dublin city centre service, which runs 24 hours a day and is one of the most frequently used airport coaches in Ireland. Aircoach also runs from Dublin Airport to Cork city, making it possible to arrive into Dublin and travel south without changing at all.
For the Dublin–Cork route, Aircoach competes with Bus Éireann on the intercity leg. Journey time is roughly 3 hours 30 minutes to 4 hours between Dublin and Cork, and Aircoach's route passes through the airport — useful if you are travelling between Cork and a Dublin Airport connection. See also our guide to booking coaches for tips on comparing operators.
Dublin: where coaches depart
Most intercity coaches depart from or near Busáras on Store Street, Dublin's central bus station, which sits a short walk from Connolly rail station and the DART line. Aircoach uses stops on O'Connell Street and St Stephen's Green rather than Busáras itself, so confirm your departure point when booking.
Dublin is not a huge city, but traffic can be very slow at peak times, particularly leaving the city southbound. Coaches on routes out of Dublin often run behind schedule during Friday afternoon rush hours — build in a buffer if you have an onward connection.
Cork, Galway, Limerick and regional hubs
All three of Ireland's other large cities have well-served coach connections:
- Cork: served by Bus Éireann and Aircoach from Dublin; also connected to Limerick, Killarney, Tralee and Waterford by Bus Éireann.
- Galway: the busiest multi-operator corridor in Ireland; also connected by Bus Éireann to Limerick and Sligo.
- Limerick: a junction point for routes between Dublin, Cork, Galway and Ennis.
Smaller towns in the west, southwest and northwest are typically served only by Bus Éireann, sometimes with infrequent schedules — check carefully before booking if you are heading somewhere off the main corridors.
Cross-border services to Northern Ireland
Bus Éireann and Translink both operate on cross-border routes between Dublin and Belfast, and between other towns in the Republic and Northern Ireland. The journey between Dublin and Belfast takes around 2 hours 30 minutes by express coach. Aileen (Bus Éireann's joint service with Translink, branded GoldLine) covers this corridor with good frequency.
Cross-border travel does not require a visa for most visitors, but note that Northern Ireland uses the pound sterling (GBP) rather than the euro, and is not part of the Schengen Area or the EU — relevant for any wider European travel planning. See our Schengen 90/180-day rule guide if you are juggling time in the EU and the UK.
Note on timetables: Irish coach services are reduced significantly on public holidays, and Sunday frequency is often much lower than weekdays. If you are travelling on a bank holiday, check timetables carefully — some routes run a Sunday schedule or less.
Tickets and booking tips
Each operator sells tickets on its own website and app; there is no single booking platform covering all Irish coaches. For comparison, a journey-comparison site shows operators and approximate timings, but fares must be confirmed on the operator's own site. Key points:
- Online booking usually saves money versus walk-up fares on busy routes.
- Most coaches allow luggage in the hold at no extra charge, though size limits apply.
- Seat selection is available on some bookings; on others seats are allocated at boarding or first-come-first-served.
- Return tickets on some routes offer a discount over two single fares.
For the Dublin–Galway corridor especially, it is worth checking all three operators (Bus Éireann, Citylink, GoBus) before booking — the price difference between the cheapest and most expensive can be significant on the same departure day.
FlixBus in Ireland
FlixBus operates a limited network of routes in Ireland, including services on the Dublin–Cork and Dublin–Belfast corridors. Coverage is narrower than Bus Éireann's network, but fares can be very competitive, particularly on advance bookings. See our dedicated FlixBus guide for how the pan-European operator works.
Frequently asked questions
What is the fastest coach from Dublin to Galway?
Citylink and GoBus typically offer the fastest services, often running non-stop or with very few stops, completing the journey in around 2 hours 15 minutes to 2 hours 30 minutes. Bus Éireann Expressway also runs the route but may make more intermediate stops on some departures.
Is there a coach from Dublin Airport to Cork?
Yes. Aircoach runs a direct service from Dublin Airport to Cork city, making it possible to arrive into Dublin and continue to Cork without going into Dublin city centre. Journey time is around 3 hours 30 minutes to 4 hours depending on traffic.
Do I need to book in advance or can I buy on the day?
On popular routes (especially Dublin–Galway on Friday evenings and Dublin–Cork at weekends), booking in advance is advisable as services can fill. For less busy routes and off-peak travel, buying at the station or on the bus is usually possible, though online booking is cheaper on most operators.
Are Bus Éireann and Translink the same company?
No. Bus Éireann serves the Republic of Ireland; Translink is the state transport operator in Northern Ireland. They cooperate on some cross-border routes, but operate independently with separate ticketing.
