When a new list of “underrated” Irish attractions makes the rounds, I always take a look. Sometimes I nod in agreement. Sometimes I roll my eyes and wonder who decided the Rock of Cashel was a hidden secret.
That was my reaction to a recent ranking from SumUp, which used everything from TripAdvisor reviews to Instagram posts and Google searches to highlight Ireland’s lesser-known spots. A great idea, if the definition of underrated doesn’t stretch to include Blarney Castle.

That said, there are a few places on the list that truly fly under the radar—and quite a few more that didn’t make the cut but should have. So let’s talk about the ones that are worth your time, how to fit them into your itinerary without going miles out of your way, and why a trip that mixes well-known highlights with lesser-visited places often ends up being the most rewarding.

Underrated – or Just Under the Radar? What’s Really Worth a Stop in Ireland
Not everything on the list was a stretch. A handful of sites are genuinely overlooked by most travelers, even if they’re hiding in plain sight. Some are just far enough off the usual routes to be missed, while others sit in popular areas but don’t get the attention they deserve.
If you're looking to skip the crowds without skipping the good stuff, these are the spots to consider adding to your itinerary.

Malahide Castle & Gardens – A Perfect First Stop
Just 15 minutes from Dublin Airport, Malahide Castle and Gardens is an easy way to start your trip -especially if you’re trying to stay awake after an overnight flight. The guided tours are engaging (even for kids), the gardens are gorgeous, and the on-site café and Avoca shop are the perfect spot to refuel. The castles setting in a charming seaside village make it feel like a gentle, scenic welcome to Ireland.
Pair it with: Malahide is a perfect day trip from Dublin – just 30 minutes by DART or bus. This is also a terrific way to refresh yourself before taking on your first day's drive.
Glasnevin Cemetery – History, Humor, and a Pint with the Dead
Yes, it’s a cemetery. But it’s also one of the best places in Dublin to get a crash course in Irish history. The Glasnevin guided tours are anything but dull, and if you time it right, you might catch a re-enactment or costumed guide that brings the stories to life.
Don’t miss: A pint at John Kavanagh’s pub next door—known locally as The Gravediggers.
Pair it with: A visit to the nearby Botanic Gardens or following a tour of Kilmainham Gaol to continue your history lesson.
Spike Island – Ireland’s Alcatraz (But Older and Creepier)
Sitting in Cork Harbour, Spike Island was once a monastery, then a fortress, and eventually one of the largest prisons in Europe. It’s a fascinating (and chilling) half-day experience, but be prepared – between the ferry ride, guided tour, and time on island, you’ll need 3.5 -4 hours.
Pair it with: Cobh's other maritime highlights, including the Titanic Experience and a hike up Spy Hill to get the iconic shot of the Deck of Cards houses and St. Coleman's Cathedral. For safety reasons do not climb on the wall – just hold your camera (or phone) over the wall and you'll get the shot.
Salthill Promenade – Galway’s Breezy Seaside Side Step
Most visitors to Galway stick to the colorful Latin Quarter and Eyre Square, but a walk along the Salthill Promenade gives you sea views, fresh air, and a more relaxed pace. If you’re lucky, you might even spot someone kicking the “kicking wall” at the end for good luck.
Salthill is about an hours' walk from the Latin Quarter. If you're wanting to add it to a day's touring, consider the hop-on hop-off bus.
Pair it with: An afternoon exploring Galway City or as a wind-down after a day trip to Connemara.
What They Missed: Truly Underrated Stops Worth Your Time
Some of my favorite experiences in Ireland don’t show up in rankings at all. They’re not tied to big marketing campaigns or social media influencers – but they’re rich in story, scenery, and character.
Here are the spots I’d add to the list, along with ideas for how to include them without straying too far off course.
Birr Castle Demesne – Ireland’s Scientific Heart in a Storybook Setting
Tucked into the middle of the country, Birr Castle Demense feels like a fairytale estate with a twist- it played a key role in astronomical discovery. The gardens are lush and expansive, but the real surprise is the Leviathan: a massive telescope that was the largest in the world for 70 years.
Pair it with: A visit to Clonmacnoise or as a scenic detour between Dublin and Galway. It’s also an easy stop if you’re overnighting between the cities.
Scattery Island – Monastic Ruins with No Crowds (and a Boat Ride Bonus)
Located in the Shannon Estuary, this uninhabited island is home to a round tower, ruined churches, and sweeping views – all without any tour buses. You’ll need to take a short boat trip from Kilrush, but once you're there, it feels like stepping into another world.
Pair it with: A Loop Head drive or time in Kilkee. Great for travelers basing in west Clare and looking for something quieter than the Cliffs of Moher.
Cahir Castle – An Intimidating Fortress with a Surprising Picnic Area
Often overshadowed by its flashier neighbor, the Rock of Cashel, Cahir Castle is one of Ireland’s largest and best-preserved Norman castles (keep your eyes peels for cannonballs!). Visitors can duck into the dungeon or climb to the tops of towers. Grab a sandwich and crisps at the cafe across the street before crossing the river to the parkland behind the castle for a picnic.
Pair it with: A visit to Cashel or the Swiss Cottage nearby. It’s a perfect half-day stop on your route between Dublin and Killarney.
Mizen Head – Dramatic Cliffs, Sea Air, and Seals
Ireland’s most southerly point comes with a scenic drive, a dramatic bridge crossing, and views that rival the Cliffs of Moher – without the crowds. You might even spot seals lounging near the rocks below the signal station.
Pair it with: A stay in West Cork or as a very scenic drive from Kenmare or Killarney to Kensale (plan a full day). Make sure to check opening times, especially outside of summer.
Westport House – Built on a Pirate Legacy (Literally)
Westport House sits on the foundations of one of Gráinne Ní Mháille castles—you may know her as Grace O’Malley, Ireland’s legendary Pirate Queen. Inside, you’ll find elegant rooms and family history; outside, acres of parkland, a lake, and seasonal attractions that make it especially fun for families. It’s a site that surprises people—historic, scenic, and far more than just another stately home.
Pair it with: A climb (or photo op) at Croagh Patrick (don't miss the moving famine memorial sculpture across the road!), or a bike ride along one of the coastal greenways.
Inishowen Peninsula – A Scenic Loop Full of Surprises
Ireland’s northernmost point doesn’t get the love it deserves, but a drive around Inishowen delivers stone forts, famine history, a disappearing lake, and Malin Head – the actual tip-top of the island. You’ll even find a “magic road” that defies gravity (or at least seems to).
Tip: Contact Adam Stewart at Flat Cap Adventurers for an off-road adventure you won't soon forget!
Pair it with: A day trip from Derry or a side trip as you enter or leave Northern Ireland. Allow a full day to explore the loop.
Let’s Be Honest: These Spots Aren’t Exactly Under the Radar
Some of the sites on the original list are well worth visiting, but calling them underrated might be a bit generous. These are the places that regularly appear on “must-see” lists, sell out in advance, or are already firmly on the tourist trail.
That doesn’t mean they aren’t great. It just means they’re not quite hidden.
Skellig Michael
You can’t even get to Skellig Michael without advance planning – and that’s if the weather cooperates. It’s spectacular, but it’s no secret. Just ask the next Star Wars fan in line.
Blarney Castle
Blarney Castle
Yes, there’s more to see than the stone, but when your wait to climb to the top of the castle ruin to kiss the rock stretches on and on, it’s safe to say it’s not flying under the radar.
Kilkenny Castle
Kilkenny’s crown jewel and one of the most photographed spots in Ireland. Gorgeous? Absolutely. Underrated? Not quite. That said, Kilkenny is far more than just its castle – and most people leave wishing they’d allowed more time for exploration in Ireland’s medieval capital.
Ring of Kerry
Still the most popular scenic drive in Ireland, especially with tour buses – though the Dingle Peninsula seems determined to take that crown. For a more underrated experience, head to the next peninsula over and follow the quieter, wilder Ring of Beara.
Muckross House and Bunratty Castle
Both are standout heritage sites—just not hidden ones. Muckross draws huge crowds within Killarney National Park, and Bunratty’s medieval banquets book up fast.
Finding the Balance Between Big Names and Underrated Stops
Underrated can mean a lot of things. Sometimes it’s a place few people have heard of. Other times, it’s a stop that gets overlooked simply because it’s not on the tour bus circuit or trending on Instagram. But often, it’s a site that’s hiding in plain sight: worth your time, but easy to miss if you don’t know to look.
The best trips to Ireland don’t rely on someone else’s definition of what’s worth seeing. They find a balance – between the iconic and the unexpected, between the stops you’ve been dreaming about for years and the ones that take you by surprise.
If you’re looking for a place to start, my free Ireland itineraries include many of the spots I’ve mentioned here- underrated and marquee – woven together in routes that feel manageable, flexible, and full of those moments that make a trip truly memorable.
