Ireland itineraries: 1 week, 2 weeks and 3 weeks

Pick the length first, then the route. Each row below is the version that fits without long driving days; nights are minimums, not targets.

This is the route to take if you have one week and want the two things Ireland does best: a city with museums and pubs, and Atlantic coast scenery. Three nights in Dublin covers Trinity and the Book of Kells, Kilmainham Gaol and a Georgian streets walk without rushing. Take the train or a bus to Galway — about 2.5 hours — and spend two nights there for music, pubs and a Connemara day trip.

Then move west or south-west for the last two nights. Doolin puts you under the Cliffs of Moher and inside the Burren; Clifden puts you in Connemara with Kylemore Abbey and the Sky Road. Both need a car to be worth it, so pick the car up in Galway rather than Dublin. Finish at Shannon rather than doubling back to Dublin.

If you would rather not drive at all, base in Galway for four nights and use tours and buses for Connemara and the cliffs. You lose the freedom to stop, but you keep the trip simple.

Two weeks lets you keep Dublin and Galway and still reach Kerry and Cork without a single long driving day. The shape is Dublin → Galway → Clare → Dingle → Killarney → Cork. Dingle needs two nights for the Slea Head drive and the pubs; Killarney needs two for the national park and the Ring of Kerry.

Between Clare and Kerry, the Tarbert–Killimer car ferry crosses the Shannon estuary and saves roughly an hour against driving around through Limerick. Fly home from Cork or Shannon. If you have 10 days rather than 14, cut Clare to one night and Cork to one, and keep Dingle and Killarney intact — those are the two stops people regret shortening.

With three weeks you can add the far north-west and, if your passport allows, cross into Northern Ireland. The 14-day route above, plus Belfast and the Causeway Coast, Donegal and Sligo, is the version that uses the time well. Belfast and the Causeway Coast take two nights; Donegal two; Sligo one or two on the way south to Galway.

Northern Ireland is the UK, so most non-Irish, non-British travellers need a UK ETA or visa — check before booking. Tell the car-rental company at pickup that you intend to cross the border; some policies and fees differ. The remaining week is best spent slowing down rather than adding stops: extra nights in West Cork, Wicklow for Glendalough, or the midlands around Clonmacnoise.

Driving distances in Ireland are short but driving times are not: single-carriageway roads, tour buses and weather all slow you down. Plan on 60–70 km/h average outside motorways, and less on the west coast in summer. A route that looks like three hours on a map can take five.

Rent the car outside Dublin if you can. City traffic and parking are the worst part of the trip, and the train to Galway is easy. Book accommodation in Dingle, Killarney and Galway well ahead for May to September; those towns fill up. This is general planning information, not a booking guarantee — confirm opening times, ferry sailings and tour availability before you commit.
