Best things to do in a day in Dublin Ireland

1. Trinity College, the Book of Kells, and the Long Room Library

The Book of Kells is considered a national treasure and is one of Dublin’s most iconic attractions. This UNESCO Memory of the World artifact is kept at Trinity College in the Dublin city center.

It’s one of the reasons that Dublin is one of the top destinations in Europe!

The ancient manuscript was created around the year 800 and features intricate illuminations of the four gospels of the New Testament. It contains over 680 pages filled with stunningly detailed drawings, Celtic symbols, and illustrations of animals and plants.

To visit the Book of Kells, you’ll need to purchase a ticket. Be sure to buy your tickets in advance, as they do sell out. I didn’t realize this on my first day trip to Dublin, so I made sure to book my tickets in advance for the following weekend!

After you see the Book of Kells itself, you’ll head into the stunning Long Room Library. This was actually my favorite part of the tour.

The Long Room Library houses over 200,000 of the university’s oldest books and an impressive collection of manuscripts.

I was in awe of the stacks of ancient books, watched over by a series of busts lining the gallery. Here you’ll also find the famous “Brian Boru’s Harp“, another iconic symbol of Ireland!

While you’re at Trinity College, take some time to explore the grounds and see the beautiful Campanile! During my visit, the cherry trees were in full bloom.

Avoid the crowds with this early access Book of Kells and Dublin Castle tour and explore two of Dublin’s most famous attractions!

2. The Guinness Storehouse

The Guinness Storehouse is one of the most popular tourist attractions in Ireland, and for good reason. On your tour of this iconic brewery, you’ll earn about the history of Guinness, how it’s made, and of course, sample a pint of Guinness!

This seven-story building is home to many interactive exhibits and multimedia displays that help guests explore the history of Guinness. There’s even a section dedicated to the quirky and offbeat advertising that Guinness is known for.

The crown jewel of the experience is the Gravity Bar, where guests can enjoy a pint of Guinness with an expansive view of Dublin.

Don’t forget to bring your camera – it’s one of the most photographed spots in the city! (You can only visit the Gravity Bar with a Guinness Storehouse tour, but it includes a complimentary pint.)

I recommend that you buy your Guinness Storehouse tickets in advance. You might get lucky and be able to get same-day tickets, but why risk it?

The Guinness Storehouse is definitely a must-see attraction when visiting Dublin in one day. If you’re taking the Hop-On Hop-Off bus in Dublin, there’s even a stop right next to the Guinness Storehouse.

3. St. Patrick’s Cathedral

Visit this impressive cathedral in the heart of Dublin and admire its beautiful architecture and vibrant stained-glass windows. Take time to explore its many monuments and memorials dedicated to famous Irish figures.

One of the central figures in the history of St. Patricks’ Cathedral is Jonathan Swift. Most well known as the author of Gulliver’s Travels, Swift served as dean of St. Patrick’s from 1713 to 1745, and he is buried in the cathedral.

One of my favorite things about the cathedral is the lovely St. Patrick’s Park. Located just to the north of the cathedral, this is one of the best photo spots in Dublin. You’ll definitely want to visit during your day in Dublin.

The park is a local favorite and you’ll find Dubliners hanging out here chatting with their friends or enjoying a picnic on the lawn. The views can’t be beat!

4. Dublin Castle and the Chester Beatty Museum

Dublin Castle is a must-see attraction when spending the day in Dublin Ireland. Built in 1204, this medieval fortress is one of the oldest and most impressive buildings in the city.

As the seat of government for centuries, the castle has been associated with many important historical events and famous figures.

Dignitaries from Benjamin Franklin to Queen Victoria to John F. Kennedy were entertained at Dublin Castle. Author Bram Stoker (famous for Dracula) worked here for 12 years in the late 19th century.

It’s also home to several museums and galleries, making it one of the city’s most popular tourist spots.

Today, Dublin Castle is open to the public and offers guided tours that reveal the castle’s fascinating past as you explore its beautiful staterooms, gardens, and the Chapel Royal. (There is a fee to tour the castle.)

The castle’s gorgeous gardens (the Dubh Linn Garden) are located just to the south of Dublin Castle. It’s flanked by the Coach House Gallery to the south, which hosts exhibitions. During my visit, there was a free exhibition on glass.

Don’t miss the Chester Beatty Library, which houses a treasure trove of rare book collections, manuscripts, prints, and photographs from countries all over the world. Admire papyrus manuscripts, Japanese prints, and a wide variety of religious and historic texts and artifacts.

There’s no fee for entry, so the Chester Beatty Museum is definitely one of the best free things to do in Dublin!

5. Temple Bar

Temple Bar is one of the most famous places in Dublin. This cobblestoned street, lined with old pubs and colorful buildings, is a must-see for any visitor to Dublin. It’s located just south of the River Liffey.

At night, this area really comes alive! Here you’ll find some of the best music and nightlife in the city. Join locals at one of the many traditional Irish pubs for a pint of Guinness, listen to live Irish music, or just take in the atmosphere and indulge in some people-watching.

At Temple Bar you’ll find plenty of great restaurants and cafes that serve traditional Irish dishes as well as international cuisine. There are also a number of unique shops selling handmade items, books, and crafts.

The Temple Bar Pub is the most popular pub in Dublin’s Temple Bar district. This family-owned pub is one of the top places to visit in Dublin, so come and enjoy a pint of your favorite beer or a glass of fine Irish Whiskey.

The iconic Temple Bar is definitely one of the top Dublin Instagram spots, so come here to get photo proof of your visit to Dublin!

6. The Ha’penny Bridge

The Ha’penny Bridge is one of Dublin’s most famous landmarks. Dating from 1816, it’s the oldest and most beautiful pedestrian bridge in Dublin.

Take a leisurely stroll across the bridge for some of the best views in town, as well as to admire its distinctive cast iron arches.

The bridge gets its name from the half-a-penny toll that was once charged to cross the bridge. That’s really a nickname for the bridge, as its original name was the Wellington Bridge, and is now officially ‘Liffey Bridge’.

The Ha’penny Bridge is a great place to get an iconic photo of Dublin. For romantic couples, the bridge has become a popular spot for wedding pictures.

Take a walk along the River Liffey to appreciate the views of Dublin.

Be sure to look for the neoclassical Customs House, one of the top landmarks in Dublin. Admire its grand columns and ornate sculptures, all topped by a copper dome. It’s especially beautiful reflected in the waters of the river!

Further to the east, don’t miss the stylish Samuel Beckett Bridge. It rather looks like a graceful harp with cables for strings!

7. Grafton Street

This mile-long shopping street is one of Dublin’s premier retail destinations. With its array of shops, boutique stores, and eateries, you’re sure to find something that catches your eye or tempts your taste buds.

It’s impossible to miss the iconic bronze statue of Molly Malone – a symbol of the city’s charm and character.

Many people think it’s good luck to touch the statue’s *ahem* ample womanly features. You’ll note that Molly Malone’s bosom is quite a bit shinier than the rest of the statue.

The buskers of Grafton Street are one of the main attractions of this popular shopping area. From traditional Irish music to modern pop songs, there’s always something entertaining to listen to as you explore the street.

The buskers are really quite talented! Be sure to stop by Grafton Street for some amazing entertainment, even if you only have one day in Dublin Ireland. (And if you like what you’re hearing, be sure to toss them a couple euros in appreciation!)

8. Kilmainham Gaol

Kilmainham Gaol is the most notorious former prison in Dublin and has a fascinating history. It housed ordinary criminals alongside men and women who fought for Irish Independence.

It was built in 1796 and operated until 1924, when it was closed due to its terrible conditions. Today, the gaol is open to visitors and offers an eye-opening look at how prisoners were treated during this time period.

It was the site of many important events in Irish history, including the execution of the leaders of the 1916 Easter Rising. Take a guided tour to learn more about Kilmainham’s dark past and its role in shaping modern Irish society.

The museum is full of exhibits that tell the story of the jail’s dark past, and your tour guide will really bring those stories to life. A visit to Kilmainham Gaol is definitely one of the best things to do in Dublin if you’re interested in Irish history.

(And you might also like visiting the Crumlin Road Gaol — it’s one of the top attractions in Belfast.)

9. The National Gallery of Ireland

The National Gallery of Ireland features a collection of artworks from the 15th century to present day. Admire one of the most extensive collections of Irish art in the world.

Browse through some of the greatest works from over 700 years of European painting, including masterpieces by Caravaggio, Picasso, Claude Monet, and Rembrandt.

The gallery hosts special exhibitions throughout the year and offers plenty of tour options if you’re interested in a more insightful visit to the museum.

You’ll find the National Gallery of Ireland located between Trinity College and Merrion Square Park. Entry to the National Gallery permanent collection is free, so this is a great way to spend part of your day in Dublin!

I love free museums, don’t you?

10. St Stephen’s Green

The historic city park of St. Stephen’s Green is one of Dublin’s most popular green spaces. It’s located in the heart of Dublin at the southern end of Grafton Street, making it easy to get to from any part of the city.

Today, in addition to its picturesque gardens and fountains, you’ll also find a bandstand and a lake with ducks and swans paddling around. St. Stephen’s Green is a great place for people watching, picnics, or just relaxing in the sunshine.

At the northwest corner of the park stands the Fusilier’s Arch. And along the park’s northeastern edge you’ll find stops for various Dublin tour companies including Hop-On Hop-Off buses and Viking Splash tours.

11. Christ Church Cathedral

Christ Church Cathedral is one of the oldest and most beautiful buildings in Dublin. It dates from 1030, founded by Sitric (King of the Dublin Norsemen).

The cathedral has a long history as a place of worship, with many important events taking place here over the centuries. From royal coronations to ordinations, Christ Church Cathedral has seen it all.

Today, the cathedral offers guided tours of its grand interior. Admire the many architectural details including the medieval crypt and gorgeous stained-glass windows.

Take a tower tour to enjoy stunning views of Dublin from the top of the cathedral’s bell tower — and maybe even get the chance to ring the bells!

Some of the cathedral’s most noteworthy artifacts include a copy of the Magna Carta and a mummified cat and rat (ew). It’s also the final resting place of Strongbow, who built the impressive Kilkenny Castle (definitely one of the top attractions in Kilkenny!).

Even if you’re only in Dublin for a day, a visit to the Christ Church Cathedral is well worth it.

12. Dublinia

Wondering what the building is that is connected to Christ Church Cathedral by the stone arch? That’s Dublinia, a museum dedicated to the history of medieval Dublin.

Dublinia is an interactive museum that explores the history of Dublin from the Vikings to the present day. It’s a great place to take the kids, with its child-friendly displays and activities.

You’ll learn about Viking life, visit a medieval street complete with merchants’ houses, and get an up-close look at some artifacts from Dublin’s past. It’s not every day that you can experience the sights (and smells) of medieval life!

At the end of your visit, head up to the viewing tower for some incredible views of the city.

If you’re traveling in Ireland with your family, visiting Dublinia is one of the best things to do in Dublin with kids.

13. National Museum of Ireland

No visit to Dublin is complete without a stop at the National Museum of Ireland. This museum has four branches across Dublin and is one of the best ways to learn about Ireland’s rich cultural history.

The Natural History, Archaeology, Decorative Arts and History museums all have something unique to offer, so no matter what your interests are you’re sure to find something that piques your curiosity.

Explore the history of Ireland through its artifacts. In the Archaeology museum (the most popular), see Viking and medieval items, the Tara Brooch, and even bog mummies. Many of the artifacts are from Dublin Castle.

The Decorative Arts and History museum is a two-for-one experience. One half of the museum focuses on the military history of Ireland. The other half focuses on decorative arts such as vases and textiles. My favorite part was the extensive silver collection — I love the intricately worked patterns!

Don’t miss the small building behind the Decorative Arts and History Museum, which contains the Asgard, a conserved 1914 gun-running ship.

The National Museum of Ireland is a great place to spend an hour or two if you’re interested in learning about the history of Irish people and culture. It’s also free to visit, which makes it one of the best budget-friendly things to do in Dublin!

Spanning 712 hectares, Dublin’s Phoenix Park is the largest park within a capital city in Europe, and it’s the perfect place to spend an afternoon!

Enjoy some fresh air and take in the sights of this sprawling park that’s been home to deer, horses, and cattle since 1662. It started off as a royal hunting ground and became a public park in 1745.

Stroll along the park’s many trails or rent a bike and enjoy a leisurely bike ride around its scenic paths. Be on the lookout for monuments and statues scattered across its grounds – including the impressive Wellington Monument, which stands a whopping 62 meters tall!

Phoenix Park is also home to the Dublin Zoo, Dublin’s most popular family attraction.

Take a walk on the wild side and explore this incredible zoo, home to over 400 animals including rare species. The zoo is constantly innovating with new enclosures and interactive exhibits, as well as being involved in global conservation efforts.

15. The Irish Whiskey Museum

If you’re a fan of whiskey (or just spirits in general), the Irish Whiskey Museum is one of the best places to visit in Dublin. It’s conveniently located in the Dublin city centre just across from the Trinity College campus.

This museum is an interactive, educational tribute to Ireland’s rich distilling history. Learn about the origins and evolution of whiskey through its different exhibits, all presented with plenty of humor and enthusiasm.

17. Merrion Square

Merrion Square is one of Dublin’s prettiest parks – and it’s surrounded by some of Dublin’s most impressive buildings!

This lush park features beautiful gardens, as well as statues honoring famous Irish writer Oscar Wilde. I found this statue of Oscar Wilde, depicted reclining on this large rock, to be hilarious!

The Oscar Wilde Monument sits at the northwestern corner of the park, just across the street from the Oscar Wilde House. (A must-see for fans of this author.)

Surrounding Merrion Square are some of Ireland’s best museums, including the National Gallery of Ireland and two of the branches of the National Museum of Ireland.

On the west side stands Leinster House, a neoclassical building that houses Ireland’s parliament. And just south of that is an impressive building which serves as the office of Ireland’s prime minister.

18. The Little Museum of Dublin

Just across the road from St. Stephen’s Green stands The Little Museum of Dublin. This quirky museum dedicated to telling the story of 20th century Ireland through artifacts and oral histories, from Irish independence to popular culture.
