Ireland is routinely sold as a country you need a car to see properly, and for the far west's smaller peninsulas that's largely true. But the country's three biggest draws outside Dublin — Galway, the Cliffs of Moher area, and Killarney's lakes — sit close enough to Irish Rail and Bus Éireann/Citylink routes that a full week covering all three, without ever renting a car, is genuinely comfortable rather than a compromise.
The shape of the week
This route runs Dublin → Galway → Killarney → Dublin, using Irish Rail's Intercity network for the long legs and a mix of Citylink and organised day tours to fill in the parts the railway doesn't reach directly. It assumes you fly into and out of Dublin, easily the best-connected international airport on the island. Every leg here runs on Ireland's ordinary public transport — nothing requires a private transfer, though the Galway–Killarney connection takes a little more planning than the other legs.
Days 1–2: Dublin
Give Dublin a full two days before heading west: Trinity College and the Book of Kells, the Guinness Storehouse, and a wander through Temple Bar and along the Liffey cover the obvious ground, but Dublin's real strength for a car-free trip is how walkable and well-connected the city centre is — you won't need a taxi for most of your stay. Note that Dublin's two main Irish Rail stations, Heuston (for Galway, Cork, Limerick) and Connolly (for Belfast, Sligo), are not connected to each other by rail; a Luas tram or short taxi links them if you need both.
Day 3: Dublin to Galway
Irish Rail runs direct and connecting services from Heuston to Galway in around two hours fifteen to two hours thirty minutes; Citylink and GoBus coaches cover the same corridor from Dublin's city centre in a similar time and compete keenly on price, so it's worth comparing train and coach fares for your specific date rather than assuming one is automatically cheaper. Whichever you choose, arriving into Galway by early-to-mid afternoon leaves time to walk the compact medieval centre and Latin Quarter before dinner.
Day 4: Galway and the Cliffs of Moher or the Aran Islands
Galway is a genuinely good base for a car-free day trip rather than just a stopover. Several tour coaches run day trips from Galway to the Cliffs of Moher and the Burren, a straightforward way to see one of Ireland's most photographed landscapes without arranging your own transfers. Alternatively, a ferry from Rossaveal (with a bus connection from Galway city) reaches the Aran Islands — Inis Mór, the largest, has bicycle hire and a slower, starker landscape that rewards a full day. Either option works well as a single day out of Galway, returning to the same hotel that night.
Day 5: Galway to Killarney
This is the one leg of the week that needs a little more planning: there's no direct fast link between Galway and Kerry, and the journey — by rail via a change at Limerick, or by a combination of coach services — typically takes around four to five hours door to door. It's a genuine travel day rather than a quick hop, so treat it as one: book the connection in advance, don't schedule anything else for the day, and enjoy watching the country change from the flat limestone of the Burren into Kerry's greener, hillier landscape as you go.
Day 6: Killarney and the Ring of Kerry
Killarney is the obvious base for exploring Kerry without a car, and it's set up for exactly that: Killarney National Park, with Muckross House and Ross Castle, is walkable or cyclable directly from the town centre, and jaunting-car (horse and trap) rides through the park are a genuine local tradition rather than a tourist gimmick. For the wider Ring of Kerry — the celebrated 179 km coastal loop that most visitors otherwise drive — organised day coach tours run from Killarney and cover the full route in a single day, a sensible solution given how narrow and slow the Ring's roads are even for confident drivers — see our driving in Ireland guide for what self-driving the route actually involves, if you're weighing the two approaches. It's a different experience from self-driving, but it removes the genuine stress of Ring of Kerry driving (narrow roads, tour-bus traffic in the same direction at the same time of day) entirely.
Day 7: Killarney to Dublin, and going home
Irish Rail runs Killarney to Dublin Heuston in around three hours thirty minutes to four hours, often with a change at Mallow — check the specific connection when booking. Timed against an evening or next-morning flight from Dublin Airport, this closes the loop comfortably, arriving back in the capital with time to spare rather than cutting it fine.
Tickets, passes and booking
Book Irish Rail tickets online in advance for the best fares, particularly on the Dublin–Galway corridor, which sees the most competition and the widest fare spread between an early booking and a walk-up ticket. Citylink and GoBus sell through their own websites rather than a shared platform, so comparing all three operators (Irish Rail, Citylink, GoBus) for the Dublin–Galway leg specifically is worth the extra few minutes. Interrail and Eurail passes cover Irish Rail, though seat reservations aren't standard on Irish trains in the way they are on the continent — see our full Ireland by train guide for the wider network, and our coaches in Ireland guide for how Bus Éireann, Citylink and GoBus overlap and compete on the busiest routes.
What this loop doesn't reach
A week is enough for Dublin, Galway and Kerry properly, but it deliberately leaves out Ireland's more remote corners — Donegal in the far northwest, the Dingle Peninsula, and much of Connemara beyond Galway city itself are reachable by local bus but with considerably lower frequency and more planning required, and don't fit comfortably into a single week alongside the three destinations above. Our broader Ireland by rail and bus guide covers what the wider network can and can't reach if you're extending this trip on a future visit.
Frequently asked questions
Can you really see Dublin, Galway and Kerry in a week without a car?
Yes, using Irish Rail for the long legs and Citylink or organised day tours to fill the gaps — the Ring of Kerry and Cliffs of Moher in particular are well served by coach day trips designed for exactly this kind of car-free itinerary.
How do I get from Galway to Killarney without a car?
By train via a change at Limerick, or a combination of coach services — allow four to five hours door to door and treat it as a full travel day rather than trying to combine it with sightseeing.
Is the Ring of Kerry worth doing without a car?
Yes — organised day coach tours from Killarney cover the full 179 km route in a day and remove the genuine stress of driving its narrow roads yourself, particularly the risk of meeting tour coaches head-on on the tightest sections.
Do I need to book Irish Rail or Citylink tickets in advance?
Advance booking secures the cheapest fares, especially on the popular Dublin–Galway corridor. It isn't strictly required on most Irish Rail services, but Citylink and GoBus coaches can sell out on Friday evenings and weekends, so booking ahead is the safer approach.
