Not Everything You Need to Know, But a Good Place to Start
The sweet spot is between late May and June. You get the longest daylight hours and more settled weather (by Irish standards), meaning less rain and mild temperatures. September is also lovely for autumn colors. If you don’t mind a bit of a chill, December is magical for the Christmas lights and the lively “panto” season, though you should definitely pack a heavy coat.
For citizens of the U.S., Canada, and the UK, a visa is generally not required for tourist stays of up to 90 days. You just need a passport valid for the duration of your stay. However, if you are planning to travel onward to mainland Europe, keep in mind that Ireland is not part of the Schengen Area, so immigration checks at the airport are standard even if you’re coming from another EU country.
Dublin Airport notably lacks a rail link. Your best options are the Dublin Express or Aircoach buses, which run 24/7 and take about 30 minutes to reach the center via the Port Tunnel. A taxi will cost you between €25 and €35. If you’re traveling in a group of three or four, a taxi often ends up being cheaper and much more convenient than individual bus tickets.
If you’re staying in the city, absolutely not. Dublin is compact, highly walkable, and the streets are often congested with M50 traffic and confusing one-way systems. Public transport—the DART (coastal train), the LUAS (tram), and the double-decker buses—will get you everywhere you need to go. Only rent a car if you’re planning a multi-day road trip to the Wild Atlantic Way or the Ring of Kerry.
Trinity College is the heart of the city’s intellectual history. You’ll want to visit the Old Library to see the Book of Kells, a stunningly illuminated 9th-century manuscript. For a more sobering but essential piece of history, Kilmainham Gaol offers a powerful look into Ireland’s struggle for independence. Pro tip: Book your Kilmainham tickets weeks in advance; they sell out faster than a pint of Guinness on a Friday night.
Yes, the tap water in Dublin is safe and high-quality. You might notice a slight difference in taste compared to home due to local mineral content, but it’s perfectly fine to drink. Many pubs and restaurants will happily provide a carafe of “council juice” (tap water) if you ask, helping you stay hydrated between those famous Irish stouts.
The official currency is the Euro (€). Ireland is very tech-forward, and contactless payment is the norm almost everywhere, from high-end boutiques to local corner shops. However, it’s handy to have a small amount of cash for smaller traditional pubs that might have a minimum spend for cards, or for tipping tour guides.
Tipping isn’t as aggressive as in the U.S., but it’s appreciated. In restaurants, a 10–12% tip is standard for good service. For taxis, simply rounding up to the nearest €5 or €10 is sufficient. Interestingly, you generally do not tip the bar staff for a standard round of drinks at the bar, though a small gratuity for table service in a lounge is a nice gesture.
The Irish weather is famously unpredictable. You can experience all four seasons in a single afternoon. The golden rule is layers. Bring a high-quality, lightweight waterproof jacket (umbrellas are often useless against the Atlantic wind) and comfortable walking shoes. Even in summer, a light sweater or fleece is essential for when the clouds roll in or the sun goes down.
Dublin is a great launchpad for seeing the rest of the East Coast. Take the DART to Howth for a cliff walk and fresh seafood, or head south to Killiney for views that locals like to compare to the Bay of Naples. For history buffs, a trip to the Boyne Valley to see the ancient passage tomb of Newgrange (older than the pyramids!) is a must-do.
Very much so. Phoenix Park is one of the largest enclosed public parks in Europe and home to a large herd of wild fallow deer, as well as the Dublin Zoo. The EPIC The Irish Emigration Museum is highly interactive and usually a hit with older kids, while the Viking Splash Tour (an amphibious bus tour) is a classic, albeit loud, family favorite.
While Temple Bar is famous for its atmosphere and live music, it’s also the most expensive area for a drink. For a more local experience, head to the Creative Quarter (around South William Street) or the pubs along Baggot Street. If you want a traditional session without the “museum” feel, look for places where the locals are actually sitting at the bar—places like Kehoe’s or The Long Hall.
