Ashford Castle, County Mayo 1 Ashford Castle, County Mayo When it comes to castles, Ashford is a superstar.

Tear yourself away from the opulent interior, and you'll find an outdoor playground fit for royalty. Here, your biggest problem is going to be choosing whether to spend your afternoon practicing archery or trying out the ancient art of falconry. Our advice? Try everything.

Crom Castle, County Fermanagh 2 Crom Castle, County Fermanagh Part of the thrill of staying in a castle is playing the aristocrat. And at Crom Castle, you won’t just be living like a lord or lady, you’ll be living right next door to them. The Earls of Erne have called Crom home for generations, and the 7th Earl has opened up the West Wing of the family home to visitors looking for a taste of old-world elegance. Of course, you’re staying in a lakeside castle, so a boat trip is a must. Crom is right on the shores of Lough Erne, known for its many tiny forested islands. Once you're back on dry land again, you can explore the stunning parkland, discover the ruins of the original Crom Castle and marvel at the two ancient, gnarled yew trees, said to be the oldest in Ireland. That’s what we call a classic Crom Castle day. Lough Eske Castle, County Donegal 3 Lough Eske Castle, County Donegal Fairytale turrets? Check. Magical woodlands? Check.

Clomantagh Castle, County Kilkenny 4 Clomantagh Castle, County Kilkenny Tucked away in the heart of Ireland's Ancient East, Clomantagh Castle is an intriguing jumble of styles. Part medieval tower house, part 19th century farmhouse, the building also boasts a Sheela-na-Gig (an ancient pagan fertility symbol) carved into one of the stones. In its time, Clomantagh's been owned by everyone from a ne’er-do-well aristocrat (yes, we're looking at you, Piers Butler, 8th Earl of Ormond) to the local vet. Now, it's safely in the hands of the Irish Landmark Trust but it's available for hire for any wannabe kings or queens of the castle.
