The best castles in Ireland and how to visit them all on one tour

What makes the medieval fortresses, Georgian manor houses, and Victorian Gothic Revival estates on our Ireland tours so photographable is the interplay between their architecture and the surrounding landscapes. We’re talking forested lakeshores, rolling countryside, dramatic coastal cliffs, and manicured gardens.

The best Irish castles are where history was made, disputed, and lived. On our Castles & Manors of Ireland: Dublin, Galway & Northern Ireland tour—a curated route through two countries’ most scenic estates—you’ll feel that history when walking the grounds, sitting down for tea, and waking up inside grand rooms.

What makes Fitzpatrick Castle unique

Perched above Dublin Bay in the leafy suburb of Killiney, Fitzpatrick Castle is a historic granite fortress with wooded grounds and sweeping coastal views that stretch out across the Irish Sea. It’s castle-style living at its most dramatic. Plus, it’s right on the doorstep of one of Europe’s most storied capitals.

This spot is the perfect introduction for travelers who are new to Irish castles, and visiting on tour with us also unlocks experiences you won’t find on most Ireland tours—like an evening Dublin Bay Cruise & Dinner excursion.

Why it’s the perfect base for exploring County Dublin

• Easy access to Dublin: Our Ireland Travel Guide covers why you’ll be glad you got the chance to see Phoenix Park, St. Patrick’s Cathedral, Trinity College, and Merrion Square.
• Option to explore Dublin Bay: On our Dublin Bay Cruise & Dinner excursion, sail past island ruins and a tower made famous by James Joyce while seeing views you only get by venturing to the city’s southern stretches.
• Your welcome dinner is at the castle: Get to know your Tour Director and fellow travelers over dinner at Fitzpatrick Castle—grand times and local dishes always included.

What makes Killeavy Castle enchanting

Killeavy Castle is a restored, 19th-century, Gothic Revival landmark set on a sprawling woodland estate at the foot of Slieve Gullion. It’s also the only castle on our Castles & Manors of Ireland: Dublin, Galway & Northern Ireland tour that sits across the border in Northern Ireland’s County Armagh.

The castle’s dramatic silhouette rises above forested grounds and feels less like a hotel and more like a secret fortress. You’ll stay in elegant accommodations on the estate grounds, with the castle always right there.

Why you’ll be glad you stayed for two nights

• The afternoon tea: Dine on finger sandwiches, warm scones with clotted cream, and fine tea served inside Killeavy Castle.
• The free time: Killeavy Castle Estate is your oyster, and there’s no shortage of ways to fill your time. How about walking around the woodland paths or doing a whiskey tasting?
• The chance to get out into nature: Add our optional A Day in the Mourne Mountains excursion to wind up to Spelga Lake, a mountaintop reservoir, and finish with a bean-to-bar chocolate and whiskey tasting.
• The farewell dinner: Close out your trip by sharing a celebratory meal inside the castle—a fitting way to cap off a trip spent sleeping, dining, and exploring Ireland and Northern Ireland’s most iconic estates.

What makes Kilronan Castle the heart of your tour

Some castles are worth a photograph. Kilronan is worth a two-night stay. Set on 40 acres of manicured grounds in County Roscommon, this turreted, 19th-century estate is everything you picture when you imagine an Irish castle: moody stonework, dramatic interiors, and a forested lakeside silhouette that looks like it was lifted straight from a painting. The grandest part? You’ll stay here on on our new Ireland tour.

Why you’ll never want to leave the area

• The meal inside the castle: Settle in on your first night for an included dinner served within Kilronan’s storied walls. It’s the perfect introduction to two nights at one of Ireland’s most atmospheric estates.
• The full free day: Wander around the 40-acre grounds, sink into the world-class spa, or pull up a chair by a crackling fire—this is slow travel at its finest.
• The chance to explore Sligo: You’re on the doorstep of one of the top cities in Ireland. Sligo is compact, colorful, and brimming with unhurried charm, which neighboring Galway often gets all the credit for.
• Our Landscapes of Sligo & Pub Lunch excursion: Join a local archaeologist to walk among prehistoric passage tombs at Carrowmore Megalithic Cemetery. (It’s older than Stonehenge.)

What makes Ashford Castle so legendary

Sitting on the shores of Lough Corrib for more than 800 years, Ashford Castle is widely considered to be Ireland’s most luxurious castle estate. It’s also one of the most recognized symbols of Irish heritage and hospitality in the world.

Once home to the Guinness family, the estate is famous for its lakeside setting, stone bridge, and formal gardens that stretch out along the water’s edge. Few castles in Ireland rival it. Fewer still let you have lunch inside—but we make it happen on the newest addition to our Ireland tours lineup.

Why it’s the perfect place to spend an afternoon

• A piece of Irish history: The Guinness family called it home. Heads of state have passed through its gates. On our new tour, it’s your turn.
• A lunch in George V’s Dining Room: Named after the king who once dined here, this is one of Ireland’s most celebrated dining rooms. Your included lunch puts you right at the table.
• A way to explore the manicured gardens: This is a privilege reserved exclusively for those dining and staying at the castle—and that includes you!
