How to plan a trip to Ireland

Start 2-3 months ahead by deciding which regions matter to you (Dublin, Cork, Galway, the coasts), then book flights and accommodation in that order. Ireland works best as a 7-10 day trip where you either pick one region deeply or do a loose loop—trying to hit everything exhausts you and the roads.

Decide your trip length and style. Ireland needs at least 5 days to feel like a real visit, but 7-10 days is better. Decide upfront: Are you doing a road trip with multiple bases, or staying in one or two cities? A road trip means new accommodation every 2-3 days and constant driving. City-based means deeper exploration but more walking. Be honest about your energy—Irish roads are narrow and left-side driving is disorienting for Americans.
Choose your regions before booking anything. Don't try to do it all. Pick 2-3 regions maximum. Popular combinations: (1) Dublin + Galway + west coast, (2) Dublin + Cork + Ring of Kerry, (3) Dublin + Belfast if you're interested in Northern Ireland. Each adds 3-4 hours of driving. Write down what you actually want to see—cliffs, pubs, history, hiking, food—then cluster your choices geographically.
Book flights 6-8 weeks out. Major US carriers fly to Dublin, Cork, and Shannon. Dublin is cheapest but most crowded. Shannon is closer to Galway and the west. Prices drop sharply midweek and in shoulder seasons (April-May, September-October). Set up price alerts 3 months before. Assume $400-700 round trip from US East Coast, $500-900 from West Coast in shoulder season.
Reserve accommodation by region, not by night. For a road trip, book your 2-3 base cities first (where you'll spend 2-3 nights), then fill in overnight stops. Use Airbnb, hotels.com, or booking.com. Book 6-8 weeks out for July-August, 4-6 weeks for other seasons. Irish B&Bs are reliable and cheaper ($60-100/night) than hotels but book fast. If driving, check parking—some city centers charge €2-5 daily.
Arrange ground transport. Three options: (1) Rent a car if you're doing the countryside—budget €35-50/day with insurance, but left-side driving takes adjustment. (2) Bus network (Bus Éireann, GoBus) is cheap but slow—good for Dublin to Galway, Cork, Belfast. (3) Train (Irish Rail) connects Dublin-Cork, Dublin-Galway, Dublin-Belfast but doesn't reach small villages. For a road trip, car is essential. Book 4-6 weeks ahead for better rates. Get an International Driving Permit before you leave the US.
Plan activities by region, not as a master list. Write down 5-8 things you want to do, then group them geographically. Don't plan day-by-day yet—just cluster. West Coast: Cliffs of Moher, Galway town, Connemara, Aran Islands. South: Cork city, Kinsale, Ring of Kerry, Dingle. Dublin: Temple Bar, Guinness Storehouse, Newgrange (day trip), Trinity College. Northern Coast: Giant's Causeway (requires detour into Northern Ireland). Assign each cluster to a day or two.
Build a loose itinerary with buffer time. Rough out your days by region, but don't schedule every hour. Example for 8 days: Days 1-2 Dublin, Days 3-4 Galway area, Days 5-6 west coast drive, Days 7 Cork, Day 8 back to Dublin or airport. Leave 1 full day with no plans—weather shuts down ferries and coastal drives regularly. Build in 2-3 hour "travel days" between regions for driving, stops, and getting lost.
Sort out logistics: weather, driving, money. Ireland is cold and rainy March-May and September-November (40-50°F, waterproof jacket essential). July-August is warmest (60-70°F) but most crowded and expensive. Most ATMs are in city centers—take out €100-150 at a time. Gas is expensive (€1.30+ per liter). Budget €20-30 per tank for a full rental car. Irish food outside restaurants is affordable; inside, €15-25 for dinner.
Get visa and travel insurance sorted. US, Canadian, and Australian citizens don't need a visa for Ireland—bring a valid passport with 6+ months validity. Get travel insurance anyway (€150-250 for 2 weeks) to cover medical and trip cancellation. Irish healthcare is excellent but expensive for visitors. Check that your phone plan covers Europe or buy a local SIM (€10-20 with data).
Do a final review 2 weeks before. Confirm all bookings: flights, accommodation, car rental. Check COVID/entry requirements (as of 2024, none, but this changes). Notify your bank of travel dates. Download offline maps (Google Maps or Maps.me). Tell your accommodation your rough arrival time. Book any popular activities in advance—Cliffs of Moher ferries, Guinness Storehouse, Newgrange—these sell out in summer.

Is it worth renting a car if I'm only visiting Dublin?: No. Dublin has solid public transport (buses, trams, metro). Rent only if you're doing a road trip outside the city. Dublin traffic is heavy, parking is expensive (€3-6/day minimum), and left-side driving stress isn't worth it for city exploration. Use the bus network or just walk.
How far apart are the major cities?: Dublin to Galway: 2.5 hours by car or 2.5 hours by bus. Dublin to Cork: 3.5 hours by car or 3 hours by bus. Dublin to Belfast: 2 hours by car (Northern Ireland). Galway to Cork: 2.5 hours by car. These are driving times on narrow, windy roads—add 30 minutes if you're unfamiliar with left-side driving.
Can I do Ireland in 3-4 days?: Technically yes, but you'll mostly be driving and sitting in buses. You'll see Dublin and maybe one other city. 5-7 days is the real minimum to feel like you're actually experiencing the place instead of ticking boxes.
Is it cheaper to book a tour package or DIY?: DIY is almost always cheaper. A 7-day tour package runs $2,000-3,500 per person; DIY is $1,200-1,700. You lose flexibility on tours but gain structure if you hate planning. If you book independently, you'll spend less time in minivans and more time actually exploring.
What's the best way to get to the Aran Islands?: Ferries leave from Galway (about 40 minutes) or Doolin in County Clare (10-15 minutes). Book ferries online 1-2 weeks ahead in summer. Ferries are weather-dependent—rough seas shut them down 1-2 days per week in winter. Go in spring or early summer if possible. One island visit fills a full day.
Do I need an International Driving Permit to rent a car?: Yes, if you're renting a car and driving in Ireland. US licenses are technically valid, but rental companies often require an IDP and some police will ask for it. Get one before you leave the US (costs $20 through AAA, takes 15 minutes). It's easier than arguing at a checkpoint.
When is peak tourist season and when should I avoid it?: Peak is July-August—prices are highest, towns are crowded, and sites are packed. Avoid if you hate crowds. Sweet spot is April-May (Easter to late spring) or September-October (early fall before weather worsens). June and early September are also good, just slightly busier than shoulder season.
