Power and plugs
Ireland uses the Type G three-pin plug, the same chunky rectangular socket as the UK. Voltage is 230V at 50Hz, so US and many Asian devices need a plug adapter, and older appliances may need a voltage converter. Most phone and laptop chargers handle 230V automatically, so a simple adapter is usually enough. Buy one before you fly, as airport prices are steep.
Language basics
Everybody speaks English, but Irish (Gaeilge) appears on road signs and place names. A few words go a long way:
- Sláinte (slawn-cha) means cheers, useful in any pub
- Fáilte means welcome
- Garda is the police
- Craic (crack) means fun or good times, as in "good craic"
Irish people are warm and chatty, so expect small talk and dry humour.
What to pack
The weather is famously changeable, often four seasons in one day. Pack a waterproof jacket, layers, and comfortable waterproof shoes. An umbrella is nearly useless in Atlantic wind, so a hood beats it. Even summer rarely tops 20C, so bring a warm layer year round.
Getting connected
Free Wi-Fi is common in cafes, hotels and pubs, but patchy in the countryside, the Wild Atlantic Way, and on rural bus routes. For maps, ride-hailing and offline translation you will want your own mobile data the moment you land. An eSIM gives you a local connection without hunting for a shop or swapping a physical SIM.
Six quick tips
- Cash and cards: The euro is used in the Republic; Northern Ireland uses pounds. Cards are accepted nearly everywhere, but carry coins for rural pubs.
- Driving: Ireland drives on the left. Rural roads are narrow and winding, so allow extra time.
- Transport: A Leap Card saves money on Dublin buses, the Luas tram and DART trains.
- Tipping: Around 10 to 15 percent in restaurants if service is not included; not expected in pubs.
- Pub etiquette: Order at the bar, and if drinking in a group, take turns buying "rounds."
- Plan distances: It looks small, but slow roads mean the Ring of Kerry or Cliffs of Moher take a full day.
