The Weather: Prepare for Four Seasons in One Day: The weather in Ireland is notoriously unpredictable. The key is to dress in layers. A raincoat or windproof jacket is a must, no matter the season. A sunny day can turn into a downpour in a matter of minutes, and vice versa.

Driving in Ireland: You drive on the left. The main roads are good, but be prepared for very narrow country roads, often with one lane going both ways and stone walls on the sides. Take your time, drive carefully and enjoy the scenery.

Currency: The currency in the Republic of Ireland is the Euro (€). It is important to remember that in Northern Ireland (which is part of the United Kingdom) the currency is the Pound Sterling (£, GBP).

Tips: In restaurants, a tip of 10-15% is common if the service has been good and a service charge has not been added to the bill. It is not necessary to tip in pubs if you only order drinks at the bar.
