12 Unique Things to Do in Dublin Most Tourists Miss

Dublin’s got plenty of well-worn tourist paths. You know the spots: Temple Bar, Trinity College, Guinness Storehouse. They’re fine, sure, but if you want to actually experience Dublin the way locals do, you need to venture beyond those obvious destinations. Here are twelve genuinely unique things that’ll give you a real taste of the city.

1. Discover Marsh’s Library

Marsh’s Library, founded in 1707, is Ireland’s oldest public library and it’s genuinely special. You’ll find it tucked behind St Patrick’s Cathedral, which is exactly why most visitors miss it entirely. The interior features Baltic oak bookcases housing over 25,000 books from the 16th-18th centuries.

The atmosphere is peaceful, almost sacred. You’re welcome to browse, sit and read, or just absorb the history. The staff are brilliant and genuinely delighted to show people around. It’s one of the most atmospheric places in Dublin and costs barely anything to visit.

Location: St Patrick’s Close, Dublin 8 Opening Times: Wednesday to Saturday 10am to 1pm and 2pm to 5pm Entry: Around €5 Tip: Visit mid-afternoon when it’s quietest

2. Climb Montpellier Hill to the Hellfire Club Ruins

The Hellfire Club sits on the foot of Montpellier Hill, about eight miles south of the city. The old house ruins are genuinely eerie, and the story behind them is fascinating. The building was a meeting place for an 18th-century club of wealthy members involved in scandalous activities.

The hike up takes about 15-20 minutes and rewards you with phenomenal views across Dublin city and beyond. It’s perfect for a picnic at sunset. The walk is muddy, so bring proper shoes. You’ll feel genuinely far from the city despite being within city limits.

Location: Montpellier Hill, County Dublin (take the 16 bus towards Ballyroan) Entry: Free Duration: 1-2 hours including walk and views Tip: Go on a clear day for best views

3. Browse The Last Bookshop and Find the Secret Cake Cafe

The Last Bookshop on Camden Street is a gem itself, specialising in unusual and rare books. But here’s the real secret: you can only access The Cake Cafe by going through the bookshop. It’s a deliberately hidden little cafe serving excellent cakes and coffee.

It’s genuinely quirky and feels like finding something special because you have. Sit upstairs in the bookshop cafe, browse the shelves and feel genuinely Dublin indie.

Location: The Last Bookshop, Camden Street, Dublin 2 Opening Times: Check website (usually afternoon/evening) Entry: Free (bookshop), pay for cafe items Tip: It’s small, so go early to get a seat

4. Explore Drimnagh Castle

Drimnagh Castle is Ireland’s only castle with a full moat and was built by the Normans in the 13th century. Sitting in the western suburb of Drimnagh, it’s much more off the beaten path than Dublin Castle. The castle is intimate and tours are genuinely detailed, full of gruesome historical tales.

You’ll feel like you’ve properly discovered something, not just ticked a box. It’s genuine Irish history, not polished for tourists.

Location: Drimnagh, Long Mile Road, Dublin 12 Opening Times: Wednesday to Sunday 1pm to 5pm (check website) Entry: Around €5-7 Getting There: Bus or taxi from city centre

5. Dive Under the Grand Canal Dock Diving Bell

The Diving Bell on Grand Canal Dock is a fascinating remnant of Dublin Port’s history. It was used from 1871 during the construction of the quay walls and only went out of use in 1958. The huge orange contraption enabled people to work underwater, though conditions inside were said to be pretty uncomfortable.

The interpretative centre lets you learn about the dock workers who did difficult work inside it. It’s genuinely unusual and most visitors never hear about it.

Location: Grand Canal Dock, Dublin 2 Entry: Free (check if open before visiting) Tip: It’s right on the water, gorgeous spot for photos

6. Wander Moore Street Market

Moore Street is one of Dublin’s oldest street markets and it’s genuinely authentic. Want to hear real Dublin accents? Chat to a Moore Street vendor. Many can trace their Moore Street heritage back generations. You’ll find fresh produce, flowers and genuine market atmosphere.

It’s not trendy or polished. It’s real Dublin, and that’s exactly why it’s brilliant. Grab something to eat from a street vendor and just soak in the vibe.

Location: Moore Street, Dublin 1 Opening Times: Daily (busiest mornings) Entry: Free Best Time: Early morning for freshest produce and authentic bustle

7. Get Lost in the Dublin Mountains

Most visitors don’t associate Ireland’s capital with mountains. But the Dublin Mountains are just eight miles from the city centre. Exploring the forests is one of the most unique things to do in Dublin, not least because of the amazing views.

There are several waymarked routes of varying difficulty. A moderate hike takes 2-3 hours and you’ll see the city and bay spread out below you. It’s genuinely peaceful and surprisingly remote for somewhere so close to the city.

Location: Rathfarnham, Dublin 14 (take the 16 bus) Entry: Free Duration: 1-4 hours depending on route Equipment: Good walking shoes, check weather

8. Tour the Jeanie Johnston Tall Ship

Across from the EPIC Museum at Custom House Quay, you’ll find the Jeanie Johnston. It’s a replica of a 19th-century vessel and provides unique insight into Ireland’s history of emigration during the Famine era.

Tours are led by knowledgeable guides who tell genuine human stories. You’ll see the cramped conditions and understand the desperation of people leaving Ireland. It’s moving, educational and genuinely unique.

Location: Custom House Quay, Dublin 1 Opening Times: Daily 10am to 5pm (check website) Entry: Around €8-10 Duration: 45 minutes to 1 hour

9. Attend a Traditional Music Session at The Cobblestone

The Cobblestone in Smithfield hosts genuine traditional music sessions. Unlike polished shows, these are real musicians playing for the love of music. Arrive early, grab a quiet corner, order a soft drink and let the music wash over you.

The atmosphere is warm and welcoming. You’ll experience authentic Dublin culture in a way most tourists never do.

Location: Smithfield, Dublin 7 Entry: Usually free or very cheap Best Time: Early evening (before 9pm) for a quieter, more authentic experience Tip: Respect the circle, no photography during sets

10. Get Lost in St Patrick’s Cathedral’s Interior

While St Patrick’s Cathedral is a well-known spot, most tourists rush through. Take time to properly explore. The grand vaulted ceiling is stunning, and there’s the tomb of Jonathan Swift to find. The history is genuinely fascinating.

11. Browse the Chester Beatty Library’s Hidden Collections

The Chester Beatty Library is free and most tourists skip it. They’re missing one of Dublin’s best collections. You’ll find miniature paintings, decorative arts, manuscripts and prints from around the world.

The collections are genuinely world-class and utterly unique. It’s quiet, peaceful and genuinely fascinating.

Location: Dublin Castle, Dublin 2 Opening Times: Tuesday to Friday 10am to 5pm, Saturday 11am to 5pm, Sunday 1pm to 5pm Entry: Free

12. Experience the Dublin Literary Pub Crawl

Actors take you on a theatrical, book-themed pub tour following famous writers’ footsteps through Dublin’s cobbled streets. You’ll visit proper Irish pubs and hear stories about Joyce, Beckett and Wilde from people who clearly love the material.

Beyond the Tourist Trail

The magic of Dublin isn’t in the obvious spots everyone photographs. It’s in the quiet library behind a cathedral, the hidden ruins with city views, the market vendors who remember their grandmother working the same spot, the genuine traditional music sessions where locals gather.

These unique experiences reveal what actually makes Dublin special to the people who live here. They’re not rushing from spot to spot. They’re living in the city, which is exactly what makes it brilliant.
