What day trips can you do from Dublin without a car?

Almost all of Dublin's major day trips are accessible without a car — through organised coach tours, public buses or the DART. Wicklow/Glendalough, Kilkenny, Belfast and Galway all have good public transport or tour options. The Cliffs of Moher and Connemara are most practical by organised coach tour.

Day trips from Dublin without a car 2026: coach tours, trains and buses

Dublin without a car: more accessible than you’d think

Many first-time visitors assume they need a rental car to see Ireland beyond Dublin. They don’t. The Republic has a well-organised network of organised day tours from Dublin, plus public bus and rail services that reach most main destinations. The trade-off with organised tours is a fixed schedule; the trade-off with public transport is planning effort. Both are manageable.

This guide covers the realistic options for each major day trip, including which are easy by public transport and which genuinely require a tour. For those who do want to drive, see driving in Ireland from Dublin.

The DART: free day trips on the coast

The easiest and cheapest car-free day trips from Dublin use the DART coastal railway. All of the following are accessible on a Leap Visitor Card with no additional booking:

Howth (30 min from Connolly): The most popular and rewarding. Take the DART to Howth, walk the coastal cliff path (5–6km loop), have chowder at the harbour. Free except transport (~€3 each way with Leap card). See Howth day trip guide and Howth cliff walk.

Dún Laoghaire (25 min from Pearse): Elegant harbour town on Dublin Bay. The pier walk, the People’s Park Sunday market, seafood restaurants, and a ferry connection to Dalkey. See Dún Laoghaire destination.

Dalkey (30 min from Pearse): Coastal village with its own castle. Easy combination with Dún Laoghaire. See Dalkey village guide.

Bray and Greystones (35–55 min): Seaside towns at the end of the Wicklow DART line. The coastal path from Bray to Greystones is one of Dublin’s best walks. See Bray and Greystones destination.

Malahide (25 min from Connolly): For Malahide Castle and gardens. See Malahide Castle guide.

Wicklow and Glendalough: best by tour

The Wicklow Mountains and Glendalough monastic valley are the most popular day trip from Dublin, but the countryside itself isn’t served by direct public transport convenient for day-trippers.

Best option — organised coach tour: The Wild Wicklow and Glendalough day tour (from €35) covers the Sally Gap mountain road, Glendalough and often includes a sheepdog demonstration. Departs from central Dublin around 08:30–09:00, returns late afternoon. Comfortable, informative and hassle-free. Alternatively, the Glendalough and Wicklow Mountains full-day trip (€28) is excellent value.

Public transport option: Dublin Bus route 65 serves Blessington; St Kevin’s Bus runs from Stephen’s Green to Glendalough (twice daily in summer, less frequently off-peak, ~€15 return). The bus leaves you at Glendalough village. This works but requires checking the schedule carefully — the last return bus from Glendalough is early afternoon, limiting time there.

See Wicklow and Glendalough day trip guide for detailed comparison of tour options.

Kilkenny: excellent by train or bus

Kilkenny is one of the best day trips reachable by public transport from Dublin.

By train: Irish Rail runs 3–4 services daily from Heuston Station to Kilkenny (with a change at Kildare or direct). Journey ~1.5 hours. Kilkenny station is a 15-minute walk from the medieval castle and city centre. Book at irishrail.ie.

By Bus Éireann / JJ Kavanagh: Direct buses from Busáras to Kilkenny, several per day, about 2 hours. Cheaper than the train.

Organised tour: If you want guiding and hassle-free logistics, tours are available but less necessary here than for Wicklow — Kilkenny is compact and easy to navigate independently. See Kilkenny day trip guide.

Cliffs of Moher: coach tour is the realistic option

The Cliffs of Moher are in County Clare on the Atlantic coast — a 2.5–3 hour drive from Dublin. There is no practical direct public transport from Dublin to the Cliffs for a day trip.

Best option — organised tour: The Cliffs of Moher full-day tour from Dublin (from ~€35–45) covers 12–13 hours return, typically via Limerick or the Burren. It’s a long day but the only realistic car-free option. Book at least a week ahead in summer. See Cliffs of Moher day trip guide.

Combining with Galway: The Galway and Cliffs of Moher day tour covers both in a very full day. Some operators drop you in Galway and you take the train back to Dublin independently.

Belfast: train or bus, very easy

Belfast is one of the easiest car-free day trips from Dublin.

By Enterprise train: 2 hours from Connolly to Belfast Grand Central. Runs multiple times daily. About €25–35 single. Very comfortable. See Dublin to Belfast transport.

By express bus: Translink Goldline and other operators run frequent services from Busáras to Belfast Europa Bus Centre. About 2–2.5 hours, €10–20.

Organised tour with Titanic: The day tour to Belfast and Titanic Museum (~€45) includes return coach transport and Titanic Belfast admission — good value compared to train plus museum entry separately.

See Belfast day trip guide.

Galway: train or bus

Galway is 3 hours from Dublin by rail (Heuston to Galway), with multiple trains daily. It’s a full day out if doing it independently — arrive around midday, explore for a few hours, return evening. Irish Rail direct services make this feasible; book at irishrail.ie.

For a more structured day that includes the Cliffs of Moher and the Burren, an organised tour is more efficient but very long (13 hours). See Galway day trip guide.

Giant’s Causeway: coach tour only from Dublin

The Giant’s Causeway is in County Antrim, Northern Ireland — about 2.5 hours from Dublin by fast car. Without a car, a coach tour is the only practical option for a day trip. These run regularly and typically pair the Causeway with Dark Hedges and Belfast.

The Giant’s Causeway, Dark Hedges, Dunluce and Belfast tour covers the Causeway Coast highlights in 12 hours from Dublin. A long day but one of the better day-trip itineraries available. See Giant’s Causeway day trip guide.

Cork and Blarney Castle: train or bus

By train: Heuston to Cork Kent Station takes 2.5–3 hours. Multiple services daily. Blarney is a 30-minute bus journey from Cork centre (Bus Éireann 215).

By coach tour: Various operators run Cork and Blarney Castle day trips from Dublin (~€55–89). These are very long days (13 hours) and may not be worth the fatigue versus overnighting in Cork. See Cork and Blarney day trip guide.

Newgrange and the Boyne Valley

The Newgrange megalithic passage tomb is in the Boyne Valley, about 50km north of Dublin. There’s no direct public transport from Dublin to the visitor centre.

Best option — organised tour: Several operators run Newgrange day tours from Dublin covering the Brú na Bóinne visitor centre, Newgrange, and often Hill of Tara. About 7–8 hours. Entry to Newgrange itself requires booking through the visitor centre regardless of how you arrive.
