From Northern to the Republic of Ireland, the stunning landscapes, forest green shades and melodic nature have rightfully earned the country the nickname ‘the Emerald Isle’. The country has a rich heritage in the form of prehistoric monuments, ancient ruins, fortified palaces and, of course, spectacular Irish castles to make you feel like a princess. From crumbled ruins to lavish hotels, I went on a hunt for the best Irish castles.

While there is no official count (rumor has it that there’s over 30,000!), there are thousands of castles in Ireland entwined with strange myths and legends, the beauty of rumbling ruins and towering fortresses. Whether you wish to explore on your own, take a tour or stay the night in a castle hotel, here are the best castles in Ireland to add to your bucket list.

15 Captivating Castles in Ireland to
Tour or Stay on Holiday

1. ✦ Dromoland Castle

If you are seeking a truly luxurious Irish vacation with Celtic vibes, Dromoland Castle is a perfect option. The five-star castle hotel allows you a chance to live like kings and queens. The hotel is a fine combination of old-world elegance and contemporary comforts where you will be treated like royalty.

The 16th-century castle is encapsulated by lush gardens dotted with swaying trees, roses, and lily ponds. There is vast 18-hole championship golf course, walking and hiking trails, a tennis court, and opportunities to try mountain biking, archery, clay pigeon shooting and falconry.

We spent a morning there learning the art of falconry, and later in the day at Dromoland’s Afternoon Tea, a long standing tradition, filled with delicious pastries, bite-size sandwiches and of course hot tea.

2. ✦ Blarney Castle

Situated 8 km from Cork City, the medieval stronghold houses the famous Blarney Stone that lures thousands of people to kiss it. Myself included! There is a mysterious block of carboniferous limestone set into the wall below the battlements, and to kiss it, the person has to hold the railing and lean backwards.

Rumor has it that the one who kisses the stone is endowed with ‘blarney’ that is, the gift of the gab. I initially went to the castle for a chance to kiss the stone in hopes to procure some eloquence and charm. Not so sure it worked.

But, there more to this place then simply the famous stone. Just take a look at the Irish castle and its surroundings, and you will feel history dripping down its each block. Apart from the stone, there are lavish gardens, brooks and streams, and woody arboretums. Visit the Bog Garden that has some of oldest trees, waterfalls and a wooden boardwalk lined with Giant Rhubarb.

Then there is the Seven Sisters which is named after the tragic tale of a king and his children boasting beautiful flowers and mystical rocks. If you dare, enter the Poison Garden. You will find some of the most toxic and poisonous plants caged up. After exploring the many gardens, visit the utterly romantic Rock Close and walk down the Wishing Steps, make an exhilarating climb to the battlements, check out the Witch Kitchen and its dying embers and explore the castle from every angle.
