There’s a side of Ireland that doesn’t often make the postcards, quiet castle ruins wrapped in ivy, coastal paths that wind around ancient cliffs and meals so local they barely made it off the farm. Beyond the usual tourist trail lies a landscape rich in raw beauty and authenticity, waiting for curious travelers to slow down and look closer.
Shining a light on Ireland’s lesser-known treasures is easier than you might think. From forgotten fortresses with haunting histories to culinary moments you’ll never find in a guidebook, here are a few that capture the unique spirit of the Emerald Isle.
Whether you’re a return visitor chasing something new or a first-timer who prefers the path less taken, these under-the-radar experiences offer a deeper connection to the soul of Ireland.
Secret Castles & Ruins
Even if castles aren’t at the top of your list when planning a trip to Ireland, you’re almost certain to encounter at least one along the way. While iconic sites like Dublin Castle or the legendary Blarney Castle (with its famous stone said to bestow the gift of gab) draw the crowds, many others quietly impress by flying under the radar.
One such hidden gem is Blackrock Castle in Cork. Built in the 16th century from limestone, it once served as a coastal fortification against pirates and naval attacks. Today, it is home to an award-winning interactive astronomy center and observatory.
Further west, along the windswept Wild Atlantic Way, you’ll find the atmospheric Ballynahinch Castle in Connemara. Once connected to formidable figures like pirate queen Grace O’Malley and the storied O’Flaherty clan, this historic estate now welcomes guests to explore its storied halls and tranquil, wooded grounds.
Underrated Coastal Island Adventures
Ireland boasts nearly 2,000 miles of coastline and is surrounded by over 380 islands, making it a dream destination for ocean lovers and off-the-beaten-path explorers. Your trip may include a visit to the iconic Aran Islands, famous for the beloved, intricately patterned Aran sweater and for ancient stone forts. Made up of three islands, Inis Mór, Inis Meáin and Inis Oírr, but the latter is the smallest and lesser known. Inis Oírr, or Inisheer as it’s also known is the most easterly island of the grouping but offers a slower pace, post-card perfect setting and ancient ruins. One unmissable highlight is the shipwreck of the MV Plassy, dramatically stranded on the island’s eastern shore. Snapping a photo “holding up” its rusted frame has become a fun tradition for visitors. For the full experience, hop on a bike or join a local guide for a scenic loop around the island’s storied landscapes on a day trip from Doolin with a local expert.
Hidden Culinary Delights
“To travel is to eat,” as the saying goes and in Ireland, there’s no shortage of unforgettable flavors to discover. From the famous pint of Guinness to the traditional stews, boxty and soda bread, you’ll encounter delicious bites throughout your trip. Uncovering the unique dishes of Ireland makes for an adventurous journey for you and your tastebuds.


If you are looking for a different kind of snack, try seaweed foraging during the Deluxe Seaweed Experience, where you can sample a variety of edible sea plants. You’ll learn about the health benefits of seaweed and try it fresh from the sea in all its earthy, briny and surprising deliciousness.
For another hidden culinary gem, try a handmade scoop of ice cream from Murphy’s Ice Cream, made with local ingredients and flavors like Dingle sea salt, caramelised brown bread and even, yes, seaweed.
