Ireland is easy to fall for and surprisingly hard to plan. The island looks tiny on a map, but narrow roads, coastal detours, sudden weather and one more tempting village turn a short drive into a whole day. You can walk through Georgian Dublin in the morning, stand beside a thousand-year-old monastic ruin in the afternoon, and end the night in a small pub while a fiddle starts up in the corner. A little preparation buys you more of that and fewer headaches. Here are the 35 things worth knowing first.
Ireland at a glance
- Currency: euro (EUR) in the Republic, pound sterling (GBP) in Northern Ireland
- Languages: Irish and English
- Time zone: GMT in winter, UTC+1 in summer
- Driving: on the left. Kilometres in the Republic, miles in Northern Ireland
- Power: Type G three-pin sockets, 230V, same as the UK
- Emergencies: 112 or 999
- Data: install an Ireland eSIM before you fly
Check your government’s official advisory shortly before you go (Smartraveller in Australia, the FCDO in the UK, the State Department in the US). Ireland is generally very safe; the notes below are about smoothing the trip, not surviving it.
Before you fly
1. Check your passport early
Confirm your passport meets Irish immigration’s validity requirement and that you have a blank page. Officers can ask for accommodation bookings, an onward flight and proof you can support yourself. Being visa-exempt is not a guarantee of entry; the border officer makes the final call.
2. Ireland is not in the Schengen Area
This trips people up constantly. Ireland is in the EU but not Schengen, so a Schengen visa does not cover it. Travellers from Australia, the UK, the US and many other countries currently enter visa-free for short tourist stays of up to 90 days, but confirm your nationality’s rules with official Irish Immigration before booking.
3. Northern Ireland has its own entry rules
The island holds two jurisdictions: the Republic of Ireland, and Northern Ireland, which is part of the United Kingdom. There are no routine checks on the land border, but you must still meet UK entry requirements to be in the north. Most non-UK, non-Irish visitors now need a UK Electronic Travel Authorisation (ETA), applied for and paid online in advance. Sort it before you book, not while driving toward the Giant’s Causeway.
Decide whether your route crosses into Northern Ireland before you book anything. It changes your entry paperwork, your currency, and, as tip 32 covers, your mobile coverage.
4. Sort your data before departure
Ireland runs on your phone: airport navigation, live bus and train times, toll payments, attraction tickets, your host’s number and the all-important Eircode (tip 26). Install an Ireland eSIM on Wi-Fi at home and you land connected, normal SIM still in place for calls and texts. Before boarding: label the line Ireland Data, keep your home SIM as default for calls, turn its data roaming off, and switch the travel line on with roaming enabled when you land.
5. Buy real travel insurance
Some countries (Australia among them) have reciprocal healthcare arrangements covering limited emergency treatment in Ireland’s public system. That is not travel insurance: it will not cover repatriation, private care, missed connections, rental-car damage or lost belongings. Insure the whole journey, including any time in Northern Ireland or the rest of the UK.
6. Carry medication properly
Bring enough for the trip in original packaging in your hand luggage, with a copy of the prescription. Note the generic name of each medicine, not just the brand, since names differ from home.
7. Expect the weather to change hourly
Ireland’s mild oceanic climate means a sunny breakfast guarantees nothing about the afternoon, and the coast feels colder and windier than the number suggests. May, June and September give long days with thinner crowds; July and August are busiest and priciest. Rain is possible every month, so use Met Éireann for forecasts and county warnings, and never build a plan that depends on a dry day.
Line up one indoor option for every outdoor day: a castle, museum, distillery or food tour. It rescues the wet afternoon that will eventually arrive.
8. Pick fewer regions than you think
Dublin and the Ancient East for cities and history, Galway, Clare and Connemara for music and the Cliffs of Moher, Kerry and West Cork for the scenic drives, Donegal for wild quiet coastline, and Northern Ireland for Belfast and the Causeway Coast. Seven days fits Dublin plus one region; ten to fourteen fits two or three without turning the holiday into a race.
Driving and getting around
9. Distances are deceptive
Motorways link the big cities, but the best scenery sits well off them, down roads with sharp bends, farm traffic, sheep, single-lane bridges and constant photo stops. A hundred rural kilometres feels nothing like a hundred motorway kilometres. Add at least 20% to every online driving estimate through the countryside, more when the drive is the point.
10. You may not need a car at all
For a Dublin city break, skip it: buses, Luas trams, DART and taxis cover everything, and a car just adds parking and toll headaches. A car earns its keep on the Wild Atlantic Way, rural Kerry, Connemara and Donegal. If you are doing both, collect the car the morning you leave Dublin rather than at the airport on arrival.
11. Drive on the left
Traffic keeps left across the whole island. The Republic posts speed and distance in kilometres (roads prefixed M, N, R); Northern Ireland uses miles and UK signage. The switch is easiest to forget pulling out of a quiet car park or petrol station.
Stick a small “KEEP LEFT” note on the dashboard for the first day. The dangerous moment is a right turn onto an empty road, when instinct takes over.
12. Bring your physical driving licence
A licence from home is generally fine for a temporary visit, but rental firms set their own rules and a digital licence in an app is often not accepted. Read the rental company’s country-specific terms, not just the booking summary, and check whether they require an International Driving Permit, a card in the main driver’s name, or written permission to cross into Northern Ireland.
13. Understand the rental insurance
The headline price is rarely the real one. Check the excess, tyre and windscreen cover, single-vehicle and undercarriage damage, cross-border permission and the fuel policy. Film a slow walk-around of every panel, the wheels, windscreen, roof, interior and fuel gauge before you drive off, and film it again on return with the location and mileage.
14. Dublin’s M50 has a barrier-free toll
Most Irish tolls have booths, but the M50 around Dublin charges with no barrier: if the car is not registered for auto-payment, the toll must be paid by 8pm the next day or penalties stack up. Rental companies handle this differently, so ask exactly how M50 tolls are billed before you leave the desk, and save the answer.
15. Use a Leap card in Dublin
The TFI Leap Visitor Card gives unlimited travel for a set period on Dublin buses, Luas, DART and commuter rail; a standard Leap card beats cash fares too. Pair it with the TFI Live app for real-time times.
16. Intercity transport is good, rural is thin
Trains and coaches connect Dublin, Belfast, Cork, Galway, Limerick and more perfectly well. Remote beaches, trailheads and rural B&Bs are harder, served patchily by TFI Local Link and private coaches. Always check the last return service before setting out, especially on Sundays and holidays.
Money
17. Two currencies on one island
The Republic uses euro, Northern Ireland uses pound sterling. Cards work widely on both sides, but keep some cash for rural pubs, markets, parking machines and tips. If you are crossing the border, carry a little of each and store them separately so you do not hand over the wrong notes.
18. Always pay in the local currency
When a terminal offers to charge you in your home currency, decline: that is dynamic currency conversion, and it lets the machine pick a worse rate. Choose euro in the Republic, pounds in the north, and let your own bank convert.
19. Ireland can be pricey, so book early
Accommodation, car hire and restaurant meals add up fast, especially in Dublin and summer. Rural towns often have only a handful of rooms that sell out around festivals, bank holidays, rugby weekends and St Patrick’s Day. Book your first night, last night and any small-town stays first; flexible city rooms are easy to replace, a room in a remote village is not.
20. Reserve the limited-capacity attractions
Timed entry or small capacity means booking ahead for Kilmainham Gaol, Newgrange, the Book of Kells, the Guinness Storehouse, Titanic Belfast and the Skellig Michael boats. Last admission is often well before closing, and the visitor entrance is not always where the map pin sits.
Pubs, food and etiquette
21. Learn the pub order
In many traditional pubs you order and pay at the bar, not at the table. In a group, rounds are the norm: one person buys for everyone, then someone else gets the next. You do not have to join a round, but say so early. And not every pub has music every night, so ask the staff what time a session starts.
22. The kitchen closes before the bar
An open pub does not mean food is still served, and in small towns kitchens can shut surprisingly early, with different Sunday hours. If you are driving through rural Ireland, eat before 7.30pm unless you have confirmed a later booking.
23. Tipping is welcome, not automatic
There is no US-style obligation here. Around 10% is appreciated for good restaurant service if no service charge is already added; tipping taxis, bar staff and hotel staff is optional. You do not tip for each pint at the bar.
Language and finding your way
24. Irish is a living language
English is spoken everywhere, but Irish is the Republic’s first official language, and in Gaeltacht areas signs may be in Irish only. A few words go a long way: fáilte (welcome), sláinte (cheers), go raibh maith agat (thank you), and crucially fir (men) and mná (women) on bathroom doors. An Lár on a bus means city centre.
25. Place names come in several versions
A town may appear under its English name, its Irish name, or both: Dingle is Daingean Uí Chúis, Galway is Gaillimh, Dublin is Baile Átha Cliath. Similar names also sit in different counties. Save the exact map pin and include the county when searching for rural stays.
26. Navigate by Eircode
An Eircode is a seven-character code for a specific address in the Republic, far more reliable than a rural road name in a map app. Ask your accommodation for theirs before you arrive and paste it straight into navigation. Northern Ireland uses UK postcodes instead.
Save every Eircode offline. Mobile coverage can fade on the final rural approach, exactly when you need the pin most.
Staying safe
27. Take cliffs and coasts seriously
Ireland’s headlands are stunning and genuinely dangerous: sudden gusts, unfenced edges, slippery ground, big waves and fast tides. Stay behind barriers, follow local signs, and never edge closer for a photo. The Coast Guard is reachable on 112 or 999.
28. Check conditions before hiking
Mountain and coastal weather turns quickly. Check the forecast, allow daylight, wear proper footwear, carry water, tell someone your route, download the map offline, and turn back if visibility drops. A popular trail is not automatically an easy one.
29. Watch belongings, especially in cars
Ireland is safe but petty theft happens in cities, on transport and at busy attractions. The specific one to know: thieves target rental cars at scenic car parks, expecting luggage inside. Do not move valuables to the boot after you park, someone may be watching. Stow them before you arrive.
30. Normal nightlife sense
Irish pubs are welcoming; a big night out still wants the usual care. Watch your drink, keep your phone and wallet secure, use a licensed taxi, and know how you are getting home before the last round. Drink-driving laws are strict, so the safe rule is zero if you are driving.
Data across the border, and pace
31. Check whether your plan covers Northern Ireland
This is the one that catches eSIM buyers out. A plan sold as “Ireland” usually means the Republic only. Cross into Northern Ireland and your phone hops onto a UK network, with no checkpoint to warn you. If your trip includes the north, check the coverage list on a multi-country Europe eSIM: when it lists the United Kingdom, a single plan covers your whole island loop without a second thought.
Download offline maps for both sides of the border before you set off, so a network switch near Belfast never leaves you guessing.
32. Pack for Type G plugs and real rain
Ireland uses UK-style Type G three-pin sockets at 230V, so bring an adaptor (most modern chargers handle the voltage automatically, but check the label). Then pack for weather: a hooded waterproof jacket beats an umbrella in coastal wind, plus layers, water-resistant shoes and a spare pair of socks kept dry in your day bag.
33. Stay in fewer places
Two or three nights per base makes the whole trip calmer than a new hotel every night. You lose less time packing, checking in and hunting for parking, and you actually get to know a place.
34. Confirm ferries and island trips on the day
Weather reshuffles or cancels boat services with little notice. Confirm before driving a long way to a pier, and treat any island day trip as weather-dependent.
35. Leave room for the unplanned
Ireland rewards slow travel more than almost anywhere. A ten-minute coffee becomes a long chat with a local; a random road sign leads to an empty beach or a ruined abbey; a grey morning clears into a golden Atlantic evening. Do not book every hour. The best Ireland tip is the plainest one: plan fewer places, and give each the time it deserves.
