Is Dublin Safe for Tourists?

One of the most common concerns for international visitors is safety in Dublin. The good news is that Dublin is generally very safe for tourists, consistently ranking among the safest European capitals. Ireland scores 1.26 on the Global Peace Index, ranking #2 globally behind only Iceland*.

That said, like any major city, you should exercise normal urban precautions:

  • Avoid displaying expensive jewelry or electronics openly
  • Stay aware of your surroundings, especially at night
  • Keep valuables secure in crowded areas like Temple Bar
  • Use licensed taxis or ride-sharing apps after dark
  • Trust your instincts if a situation feels uncomfortable

Local Tip: While the November 2023 riots made international news, such incidents are extremely rare in Dublin. The city quickly returned to normal, and visitors shouldn’t be deterred by these isolated events.

Getting Around Dublin

Dublin is a compact, walkable city, but understanding the transport options will help you maximize your time. First-time visitors often find Dublin surprisingly easy to navigate. Check out our complete guide to getting around Dublin for detailed information.

Public Transportation

  • Dublin Bus: Extensive network covering the entire city (€2.00-€3.10 per journey*)
  • LUAS Tram: Two lines (Red and Green) connecting key areas (€2.00-€2.60 per single journey*)
  • DART Train: Coastal railway perfect for trips to Howth or Dún Laoghaire (€2.00-€2.60 per single journey*)
  • Leap Card: Prepaid card offering discounts on all public transport (€5 deposit + credit)

Other Options

  • Walking: Most city center attractions are within 20-30 minutes’ walk
  • Taxis: Readily available but more expensive than US cities (€10-20 for most city journeys)
  • Ride-sharing: Uber doesn’t operate in Dublin, but the FREE NOW app works similarly
  • Bike Rental: Dublin Bikes stations throughout the city (free for the first 30 minutes, then €3.50 for the day)

Money-Saving Tip: Buy a 3-day Leap Visitor Card (€19.50) for unlimited travel on Dublin Bus, LUAS, and DART within the Short Hop Zone. One of my sisters kindly got my son and me regular Leap Cards a few years ago, and we always use them when visiting family and traveling around the city. The Leap Card really is so handy.

When to Visit Dublin

Dublin welcomes visitors year-round, but each season offers different experiences. For detailed seasonal information, see our guide on the best time to visit Dublin.

Peak Season (June-August)

  • Pros: Warmest weather (average 68°F/20°C), longest days (sunset after 10 PM), outdoor festivals
  • Cons: Highest prices, largest crowds, accommodation books up quickly

Shoulder Season (April-May, September-October)

  • Pros: Pleasant weather, fewer crowds, lower prices, spring flowers or autumn colors
  • Cons: More rain than summer, some attractions have reduced hours

Low Season (November-March, except St Patrick’s Day)

  • Pros: Lowest prices, authentic local atmosphere, Christmas markets (December), St. Patrick’s Festival (March)
  • Cons: Cold and wet (average 48°F/9°C), shortest days, some attractions may close, but most will be on reduced hours due to reduced daylight

Special Events to Consider:

  • St. Patrick’s Festival (March 15-19): Book accommodation 3-6 months ahead at least, as it is a busy time in Dublin as well as other major cities in Ireland
  • Dublin Pride (typically at the end of June): Colorful celebrations throughout the city
  • All-Ireland Finals (July): City buzzes with GAA excitement
  • New Year’s Festival (December 31): Spectacular celebrations

Entry Requirements for International Visitors

Entry requirements vary by nationality, but Ireland has straightforward immigration policies for most visitors.

Visa Requirements

For first-time visitors, it’s important to know:

  • EU/EEA Citizens: No visa required, freedom of movement applies
  • UK Citizens: No visa required due to the Common Travel Area agreement
  • US, Canadian, Australian and New Zealand Citizens: No visa required for stays up to 90 days. You don’t need to pay a fee nor apply ahead of your arrival. And you do not need extra validity on your passport other than for the duration of your visit.
  • Other Nationalities: Check with the Irish immigration website for specific requirements
  • All visitors need a valid passport (validity requirements vary by country)
  • A return ticket may be requested at immigration
  • Proof of accommodation and sufficient funds may be asked for

Immigration Process

Upon arrival at Dublin Airport, non-EU visitors will go through Irish immigration, where you will receive a stamp allowing your stay (typically up to 90 days for visa-free nationals). The process is typically quick and hassle-free. First-time visitors should have their accommodation details handy.

Important for those planning to visit both parts of Ireland: If you plan to visit Northern Ireland (Belfast, Giant’s Causeway), you’ll technically cross into the UK, but there are no border checks due to the Common Travel Area. Most visitors can freely travel between the Republic of Ireland and Northern Ireland. Either way, you should ensure you have the right visa for both the Republic of Ireland AND the United Kingdom, just in case you are checked.

Bonus for Departing from Dublin, U.S. Preclearance: If you’re flying back to the U.S. from Dublin Airport, you’ll go through U.S. Preclearance before you board your flight, meaning you’ll clear U.S. customs and immigration while still in Ireland. This saves time on arrival back in the States, as you’ll land as a domestic passenger. Dublin is one of the few airports outside North America with this perk, another reason it’s a great place to end your trip!

Practical Tips for First-Time Visitors

Money Matters

Especially important for first-time visitors to know:

  • Currency: Euro (€) – not British Pounds (common misconception)
  • ATMs: Widely available, called “cash machines” locally
  • Credit Cards: Visa and Mastercard are widely accepted; American Express is less common
  • Tipping: Not mandatory but appreciated (10% in restaurants, round up for taxis, €1-2 per drink in pubs). Read my guide on when to tip in Ireland
  • Prices: Generally higher than in many European cities – budget accordingly

Practical Considerations

Essential information for international visitors:

  • Electricity: 230V with Type G plugs (three rectangular prongs) – most visitors need an adapter. Read my guide to power plugs and adapters in Ireland
  • Phone Service: Check if your carrier offers international plans; local SIM cards are readily available
  • WiFi: Free in most hotels, cafes, and pubs
  • Weather: Rain possible any time – pack layers and a waterproof jacket, regardless of season, as you never know when you are going to need it, trust me
  • Pharmacy: Called “chemists” – bring prescription medications in original containers
  • Emergency Number: 999 or 112 for all emergencies

Cultural Tips

Understanding Irish culture (particularly helpful for first-time visitors):

  • The Irish appreciate genuine interest in their culture over stereotypes
  • “Craic” (pronounced “crack”) means fun/good times in Irish slang, not drugs. Learn more Irish slang here
  • Pub culture is about socializing, not just drinking
  • Queuing (standing in line) is taken seriously
  • Small talk is common and appreciated – don’t be surprised by friendly strangers
  • “Thanks a million” is a common expression – very Irish!
  • Don’t be offended by “slagging” (good-natured teasing) – it’s a sign of affection

Top 10 Must-See Dublin Attractions

Dublin packs centuries of history and culture into a walkable city center. For a detailed guide, see my Dublin Bucket List for a list of my favorite things to do in Dublin. Here are my top 10 picks of absolute must-visits:

1. Trinity College & Book of Kells

Trinity College, Ireland’s oldest university (1592), houses the magnificent 9th-century Book of Kells and the breathtaking Long Room Library with its two-story oak bookcases. This is one of Dublin’s top attractions to visit.

Insider Tip: Book online in advance for significant savings and to skip lines. Visit early morning or late afternoon for smaller crowds. Please note that only a few books are remaining on the shelves in the Long Room as the college prepares to close the Long Room for a Redevelopment Project in 2027. You can still view the Book of Kells as normal.

Cost: From €21.50 adults (online price)

2. Guinness Storehouse

The Guinness Storehouse is somewhere that eluded me until I left Ireland! Spanning seven floors, this museum explores Ireland’s most famous export, culminating in the Gravity Bar with 360-degree city views. Fingers crossed it’s a clear day on your visit.

Don’t Miss: Learning to pour the perfect pint and enjoying it with Dublin spread below.

Cost: From €22 adults (varies by time/date)

3. Kilmainham Gaol

One of my favorite places to visit in Dublin, this former prison tells the story of Irish independence through the lives of political prisoners executed here, including the 1916 Easter Rising leaders. You get a guided tour of the Gaol as well as entry to the museum. Allow a few hours to take it all in. Those going with kids, be mindful of their ages.

Book Ahead: Tours sell out days in advance, especially in summer. Prebook via the authorized website well ahead of time

Cost: €8 adults

4. Dublin Castle

Dating from 1204, Dublin Castle is not just a castle but a large complex where you can explore the State Apartments, Medieval Undercroft, and Chapel Royal, where British rule ended in 1922 (read more about Ireland’s history here). If you have time, pop into the Chester Beatty Library as well, THE best free thing to do in Dublin.

Guided vs Self-Guided: Guided tours offer fascinating historical context worth the extra cost.

Cost: €8 adults (self-guided), €12 (guided)

5. Temple Bar District

Lots of people may tell you to steer clear of Temple Bar, but not me. I love strolling through the streets or people-watching through the windows of a cafe or restaurant. Temple Bar is Dublin’s cultural quarter with cobblestone streets, traditional pubs, street performers, and the Saturday food market. Just make sure to keep your valuables hidden and your wits about you, especially at night.

Reality Check: Yes, it’s touristy and pricey, but the atmosphere is unmatched. Visit once, then explore my non-touristy pub recommendations in Dublin.

6. St. Patrick’s Cathedral

St Patrick’s Cathedral is Ireland’s largest cathedral, and is where Jonathan Swift served as Dean. It has beautiful Gothic architecture and peaceful gardens. And there is a door where a famous saying came from. I won’t spoil it for you.

Cost: €11.50 adults

7. Phoenix Park

A place I often spent a Sunday morning with my parents, walking the dogs, is the Phoenix Park, Europe’s largest enclosed city park (1,750 acres). It is home to Dublin Zoo, Áras an Uachtaráin (President’s residence), the American Ambassador’s Residence, and wild deer, which we were always trying to spot around the Papal Cross and the Forty Acres.

Free Activity: Rent bikes to explore or enjoy a picnic while deer-watching. Note that entry into Dublin Zoo is payable.

8. National Museum of Ireland

One of the best museums to visit in Dublin is the National Museum of Ireland. They have free admission to world-class collections, including Viking artifacts, bog bodies, and Ireland’s gold. The National Museum of Ireland Archaeology branch on Kildare Street is a great place to visit when it rains in Dublin.

Three Locations: Archaeology (Kildare St), Decorative Arts (Collins Barracks), Natural History (Merrion St)

9. EPIC Irish Emigration Museum

One of my top 10 must-visit places in Dublin is EPIC, the Irish Emigration Museum on Custom House Quay. This interactive museum is perfect for anyone interested in the Irish diaspora and genealogy. Engaging technology brings emigration stories to life via 20 exhibition rooms.

Genealogy Bonus: On-site research center can help trace your Irish roots, particularly popular with visitors from the US, Canada, Australia, and the UK.

Cost: From €21.00 adults

10. Christ Church Cathedral

Christ Church Cathedral is Dublin’s oldest building, built in 1028, on the site of an old Viking church. The cathedral is incredible to visit and even has a medieval crypt containing a mummified cat and rat.

Combination Ticket: Save money with a joint ticket including Dublinia.

Cost: From €11.50 adults

Other Tips for Ireland

WHAT’S THE BEST WAY TO GET AROUND IRELAND?
If you are in a city, use the local public transportation system, especially in the Irish capital. Here is my guide to getting around Dublin.
If you’re going between cities or to smaller towns, you can usually take the train (I buy my tickets through Eurail or RailEurope).
In rural areas, train stations are rarer, so you might want to rent a car, which is easy in Ireland (I use Rentalcars or Discovercars).

DO I NEED TRAVEL INSURANCE FOR IRELAND?
It depends. If your travel insurance already covers you in Ireland, then you’re all set. If not, head for VisitorsCoverage for everything travel.

WILL MY PHONE WORK IN IRELAND? WHAT ABOUT MY CHARGER?
You can use your roaming plan in Ireland. If you don’t have one, you can do one of several things (just make sure you have an unlocked phone).
You can order a SIM card before you get to Ireland.
You can buy a SIM card from a shop in Ireland.
You can buy an e-SIM.

WHAT SHOULD I PACK FOR IRELAND?
Here are a few essentials you should NOT leave home without:
Comfortable walking shoes. You’ll be on your feet a lot, and… cobblestones and mud.
Plugs are different in Ireland. So pack a universal travel adapter.
An anti-theft purse (this is the bag I use).
A good rain jacket (for summer) or coat (for winter) because rain is frequent in Ireland. It isn’t called the Emerald Isle for nothing!

WHAT’S THE BEST WAY TO BOOK A PLACE TO STAY IN IRELAND?
I use booking.com for my own travels around Ireland. Listings are extensive, including apartments, and cancellation policies generous.
