Planning a trip to Ireland? Kevin and Kate from Happy Irish Wanderers are here to share the country’s top hidden gems.

When planning a trip to the Emerald Isle, you’ll likely prioritize visiting famous destinations in Ireland like the Ring of Kerry, the Cliffs of Moher, and the Guinness Storehouse. However, there are many more hidden gems to explore that are just as impressive, if not even better!

This guide highlights ten incredible but often overlooked destinations in Ireland. From ancient megalithic monuments to historic sites, stunning natural landscapes, and charming towns, these hidden gems offer a unique glimpse into Ireland’s rich history, culture, and natural beauty.

Starting in Dublin, the capital of Ireland, this list will take you on a journey through the country’s best-kept secrets in a clockwise direction before returning to Dublin.

So, grab your notebook and map as you’re about to discover some of the best of Ireland’s underrated destinations (as well as the fascinating history behind them!). 

1. Kilmainham Gaol: The Irish Revolution 

Dublin City is a great starting point for exploring Ireland. Many tourists start and finish their itinerary here, but often only visit Trinity College and the Book of Kells, the Guinness Storehouse, and indulge in a few more pints in the Temple Bar area afterward. 

However, this part of Dublin was once a war zone. 

On Easter Monday, 1916, Padraig Pearse stood outside the General Post Office (GPO) in Dublin and proclaimed Ireland a free and independent state. This historic declaration marked the beginning of the Easter Rising, a rebellion against British rule that would ultimately lead to Ireland’s independence.

Unfortunately, just a few days later, Padraig Pearse and 13 other leaders such as James Connolly were executed by British forces in the courtyard of Kilmainham Gaol, one of Ireland’s hidden gems.

Even if you’re not a history buff, Kilmainham Gaol is a must-visit in Dublin. Guided tours will take you through the former prison and show you where Irish leaders were held and executed. You’ll also learn about ordinary citizens who were held here, some as young as 7 years old!

To understand more about the Easter Rising and Kilmainham Gaol, you can listen to the songs “Grace” and “James Connolly” by the Wolfe Tones.

Travel Tip: It is now also possible to take a tour of the GPO and learn where Ireland’s bravest men stood and fought for freedom. Alternatively, you can take a walking tour of Dublin that includes a stop at the GPO and other key sites in the city. 

Cost: An adult ticket to the Kilmainham Gaol is €8 and includes a guided tour of the jail. Tickets are only available on the official website. Book tickets well in advance.  

2. Wicklow Mountains: Monastic Ruins & Majestic Landscapes

Just an hour’s drive from busy Dublin, a different world awaits in the Wicklow Mountains. This beautiful region is packed with breathtaking views, landscapes, and historic attractions, making it a great day trip to include on your Ireland itinerary.

One of the main attractions in the Wicklow Mountains is the Glendalough Valley and the famous Glendalough monastery. Founded by Saint Kevin in the 6th century, its well-preserved ruins and famous round tower showcase Ireland’s rich cultural heritage. Visitors can explore the historic monastic settlement for free.

The Wicklow Mountains are also home to the stunning Powerscourt Estate, which boasts some of the most beautiful gardens in the world. In fact, it was once ranked third in the world by National Geographic. Furthermore, you can also visit Powerscourt Waterfall within the grounds. At 398 feet (121 meters), Powerscourt Waterfall is among Ireland’s tallest.

Finally, no visit to the Wicklow Mountains would be complete without a visit to the Lough Tay Viewpoint. Perched atop a hill overlooking the lake, this viewpoint offers breathtaking views of the lake and surrounding mountains. Lough Tay is also known as the “Guinness Lake,” because of its dark waters and white sands resembling a delicious pint of Guinness!

Cost: The Glendalough Monastery is free to visit, as is the Glendalough Upper Lake, save for a parking fee. The Powerscourt Estate gardens cost €10 per adult ticket, while the waterfalls are a separate €7.50 ticket for adults.

3. Drombeg Stone Circle: Mystical Ancient Ruins

The next must-see attraction of Ireland’s hidden gems is a megalithic monument built over 3,000 years ago in Ireland’s largest county, and some might say the real capital of Ireland, Cork. This ancient megalithic site is the Irish version of Stonehenge – The Drombeg Stone Circle.

The Drombeg Stone Circle is made up of 16 standing stones and one flat stone measuring 3.5 meters in diameter giving it the nickname “The Druids Altar”. In ancient Celtic times, this particular stone would have been used as both an altar for ceremonial activities and astronomical observations.

Despite lacking modern technology today, the builders of Drombeg Stone Circle had an impressive knowledge of astronomy and natural cycles. For instance, they were aware of events like the winter solstice. During this period, the setting sun perfectly aligns with “The Druids Altar” stone and entrance of the circle.

If you get to witness this event consider yourself very lucky. Keep in mind that, in Ireland, rain and fog are more common than clear sunsets.

It takes over an hour to drive to Drombeg Stone Circle from Cork City, Ireland’s second-largest city. While it’s possible to drive there directly from Cork City, the best way to visit this must-see sight is to include it on a day trip starting from Kinsale.

Kinsale is a gorgeous town with picturesque streets, colorful buildings, and historic landmarks such as Charles Fort and The Old Head of Kinsale.  

From Kinsale continue to Clonakilty, birthplace of Irish revolutionary leader Michael Collins before proceeding on to Drombeg Stone Circle. Finally head to Knockdrum Stone Fort, another remarkable ancient Celtic site.

Cost: Saving the best news until last: all four attractions – Kinsale, Clonakilty, Drombeg Stone Circle & Knockdrum Stone Fort – are completely free to visit!

4. Skellig Islands: A Majestic Monastery 

Despite having nearly 30,000 castles and castle ruins, cultural monuments, and diverse landscapes, it is surprising that Ireland only has two UNESCO World Heritage sites. Three if you count The Giant’s Causeway, but technically it’s located in Northern Ireland.

The Skellig Islands are one of these UNESCO World Heritage sites and another one of Ireland’s hidden gems. Located 7.5 miles (12 kilometers) off the coast of County Kerry, the islands consist of two main islands: Skellig Michael and Little Skellig.

The main feature is Skellig Michael, an ancient monastic settlement of unique stone beehive buildings built in the 6th century. These buildings were constructed using a technique that didn’t require mortar, and despite the harsh Irish weather they remain standing to this day in remarkable condition.

You may be familiar with the unique stone beehive buildings on Skellig Michael, as they were featured in the Star Wars films “The Force Awakens” and “The Last Jedi.” The dramatic cliffs and ancient monastery of Skellig Michael provided a striking backdrop for scenes set on the planet Ahch-To, where Jedi Master Luke Skywalker was in hiding.

Travel Tip: Visiting Skellig Michael is only possible from May to October due to the strong Atlantic Ocean currents surrounding the islands. It’s essential to read the fine print when booking your trip, as not all boats offer access to the island. Skellig Island Cruises, for instance, offers both “Eco Cruises” that circle around the islands and “Landing Tours” that take you onto Skellig Michael. 

Additionally, Little Skellig is off-limits due to its inaccessibility. As a result, thousands of gannets made it their home and it is now a bird sanctuary to one of the largest gannet colonies in the world.

Cost: Ticket prices vary based on ferry operator, time of year, and tour packages. Check with individual operators for pricing. 

5. Slea Head Drive: The Best Kerry Road Trip

While many travelers prioritize the Ring of Kerry in their Ireland itinerary, there’s another hidden gem in County Kerry that often gets overlooked. The Slea Head Drive is a must-see scenic route that offers a unique and unforgettable experience for those who rent a car for their Irish adventure. 

As you embark on this Ireland road trip, you’ll find yourself surrounded by picturesque landscapes – rolling green hills, rugged stone walls, and ancient abandoned cottages.

Begin your journey in the charming town of Dingle, which is just a one-hour drive from Killarney. But before arriving in Dingle, take a brief detour to the historic South Pole Inn, a pub once owned by the renowned Irish explorer Tom Crean. This legendary pub is a testament to Tom’s incredible adventures in Antarctica with Sir Ernest Shackleton, and it’s the perfect spot to refuel and set the tone for your journey ahead.

The Slea Head Drive spans approximately 30 miles along the stunning Dingle Peninsula and Atlantic Ocean. To make the most of this journey, drive in a clockwise direction for the best views and easy access to the numerous breathtaking stops along the way.

As you drive through the scenic Dingle Peninsula, you’ll discover more of Ireland’s hidden gems, including the ancient Dunbeg Fort, offering breathtaking views of the coastline; the Gallarus Oratory, a 12th-century stone church; and Dunquin Pier (our personal favorite spot), for taking in the stunning scenery.

But wait, there’s more! Instead of ending your journey in Dingle, continue on to Conor Pass, a winding road through one of Ireland’s highest mountain passes. This will lead you to even more breathtaking views and an unforgettable experience.

Travel Tip: If you have another day to spend in Dingle, consider taking the Dingle Sea Safari out to see the Great Blasket Islands. 

Cost: Slea Head Drive is free to visit, though there are a few optional paid attractions along the route. 

6. Aran Islands: A Trip Back In Time

The Cliffs of Moher, are a must-see attraction in Ireland that offers stunning views of the Atlantic Ocean. On clear days, you can spot three islands in the distance: Inishmore, Inishmaan, and Inisheer.

Together they make up the Aran Islands, another one of Ireland’s hidden gems that don’t get the attention they deserve.

Exploring the Aran islands is like stepping back in time to experience “Old Ireland”. Each island has its own unique charm, yet they share common traits like Irish-speaking locals, traditional thatched cottages, unique karst landscapes, and ancient stone walls.

The largest island in the Aran Islands is Inishmore, and the must-see sight here is Dun Aonghasa, a 3,000-year-old stone fort that is built in a 180-degree shape on the edge of a 100-meter cliff. Inishmore also features a unique natural pool, known as the Serpents

Lair, with its almost rectangular shape you would almost believe that it is man-made. Only those who are brave or mad jump into its waters for a refreshing swim.

On Inisheer, you’ll find the iconic shipwreck of the MV Plassy. The shipwreck is featured in the opening credits of the popular TV show “Father Ted”. This hilarious Irish sitcom lovingly pokes fun at Irish culture and traditions.

Inishmaan is the quietest of the three islands, with fewer tourist attractions compared to its sister islands. However, its untouched natural beauty and serene atmosphere make it a peaceful retreat for those seeking a more off-the-beaten-path experience.

All three islands can be accessed by ferry from Doolin and Galway, or you can opt for a more luxurious experience by flying from Connemara Airport, located near Galway City there are daily flights to the islands.

Cost: Like the Skellig Islands, prices vary by tour operator, type of tour, and other factors. A ticket on this tour of the Aran Islands and Cliffs of Moher, for example, starts at €80 pe​​r person and includes a ferry ride, entrance tickets to the Cliffs of Moher, and transportation.  

7. Ben Bulben – Ireland’s Table Mountain

Located in County Sligo, Ben Bulben is a table mountain that stands tall at a height of 1725 feet (526 meters). Surrounded by breathtaking natural landscapes, it’s particularly well-suited for hiking enthusiasts.

However, if you’re not a fan of hiking, you can instead take a scenic drive through the surrounding area. The main attractions to visit around Ben Bulben are: Gleniff Horseshoe, Devils Chimney, Glencar Waterfall, Rosses Point, and Mullaghmore. All mentioned attractions are free to visit.

Ben Bulben is also a significant location in Irish literature and mythology. According to folklore, the table mountain is a place of enchantment and mystery, where supernatural beings are said to dwell. While it may sound morbid, the stunning landscape of Ben Bulben is connected to several notable graves.

In Irish mythology, it is believed to be the final resting place of the giant Fionn mac Cumhaill. As the leader of the Fianna warriors, a band of Celtic warriors, Fionn is famously associated with the creation of the iconic Giant’s Causeway on the Northern Irish coast.

In case you do not know: Fionn was challenged by a Scottish giant named Benandonner to a fight. Not wanting to fight, Fionn retreated to Ireland and hid in a cave. His wife Oonagh then came up with the idea to disguise him as a baby. Benandonner made his way to Ireland and when he saw the size of the “baby” he quickly retreated back to Scotland, destroying the causeway as he fled. The remaining columns of rock are the Giants Causeway, a natural wonder and another Irish UNESCO World Heritage Site.

The famous Irish poet W.B. Yeats is also buried nearby. Ben Bulben is famously mentioned in W.B. Yeats’s poem “The Lake Isle of Innisfree” (1890). The poem is about the poet’s longing for a peaceful, isolated life on a lake island in Ireland, and Ben Bulben is mentioned as a distant mountain that the poet can see from the island. This poem is considered one of Yeats’ most iconic works

We may as well continue with the subjects of graves, as Carrowmore megalithic cemetery is also nearby. Over 3000 years old Carrowmore is composed of over 60 passage tombs, dolmens, and stone circles, making it one of the largest megalithic complexes in the world.

Despite sounding gloomy, Sligo and the nearby Ben Bulben are fantastic places to visit and more of Ireland’s hidden gems.

Cost: Ben Bulben is free to visit.

8. Slieve League Cliffs – Europe’s Highest Sea Cliffs 

The Cliffs of Moher get all the attention and are considered a must-see sight to be included on an Ireland itinerary. Although a bit trickier to get to when compared to the Cliffs of Moher, the Slieve League Cliffs is an unbelievable sight to behold.

Standing about 2,000 feet (600 meters) high, the Slieve League Cliffs are some of the highest sea cliffs in Europe, even surpassing the Cliffs of Moher in height.

Located in County Donegal it takes about two hours to get there from Sligo Town, and two hours from Derry. The route takes you through some of the most breathtaking landscapes in Ireland.

Cost: The Slieve League Cliffs are a public access area, and you can visit without paying a fee. However, if you want to park your vehicle in the designated parking area, then there is a small fee.

9. Mussenden Temple – Cliffside Architectural Marvel

The Giant’s Causeway is a must-see sight in Northern Ireland, and many tourists visit the usual hotspots along the way such as Dunluce Castle, Carrick-a-Rede Rope Bridge, and the Bushmills Distillery.

However, there is another hidden gem that often goes unnoticed – the Mussenden Temple on the cliffs near Castlerock, a seaside village in County Londonderry.

Only 40 minutes from Derry City, the Mussenden Temple is a Greek-style temple built in the 19th century. What makes this must-see attraction in Ireland so special is the location as it was built on the edge of a 120-foot cliff overlooking the Atlantic Ocean and Downhill Strand Beach below. It offers some of the best panoramic views in Ireland of rugged coastline and the vast expanse of the Atlantic Ocean.

Mussenden Temple is also surrounded by the ruins of Downhill House, an 18th-century mansion that was once the Earl Bishop’s residence. 

Cost: Visiting Mussenden Temple and the surrounding Downhill Demesne is free of charge, except for a parking fee.

10. Newgrange: Ancient Passage Tomb of Ireland

Last on our list of Ireland’s hidden gems is a monument that is older than the Great Pyramids of Giza! Built over 5000 years ago. The Newgrange complex is located in County Meath and is only an hour’s drive away from Dublin.

The megalithic monument is part of a larger archaeological site called Brú na Bóinne (meaning “Palace of the Goddess Boann” in Irish) and is Ireland’s second UNESCO World Heritage Site.

Newgrange is a massive tomb constructed from large stones and covered in earth. But what makes Newgrange so special is that every year on the winter solstice (December 21st). The rising sun sends a beam of light through a small hole above the entrance and illuminates the entire chamber for about 17 minutes. This phenomenon is known as the “Newgrange Solstice Illumination.”

Furthermore, inside the Chamber and passageway of Newgrange, there are many triskelions carved into the walls, this iconic Irish symbol is known all across the world and it is believed to mean life, death, and rebirth.

Similar to the Drombeg Stone Circle, Newgrange’s impressive structure is a remarkable example of ancient engineering with precise alignment to the winter solstice. The fact that this was built over 5000 years ago is truly remarkable.

Cost: Entrance to the Newgrange Chamber and Brú na Bóinne is €18 per adult. Make sure to book tickets in advance because entrance is limited. Alternatively, you can join a tour from Dublin that includes entrance fees, transportation, and a stop at the 5th century St Bhuite monastery. Tickets start at €85 per person. 

Conclusion

This guide highlights ten of Ireland’s hidden gems – remarkable places that remain easily accessible while offering a deep connection to the country’s history and culture. Best of all, most of these incredible sites are free to visit!

From the towering Cliffs of Slieve League and the striking Ben Bulben Table Mountain to the ancient mysteries of the Drombeg Stone Circle and Newgrange Tomb, these unforgettable destinations promise breathtaking landscapes and fascinating stories that will make your trip to Ireland truly special.
