Ireland's 10 Most Fascinating Islands

An island among islands, Ireland looks out to some 80 isles from its shores, each with their own unique characteristics and story. While most are home to locals and vacationers, 20 of these islands remain uninhabited.

Time moves more slowly on an island, isolated from the mainland with fewer influences and foot traffic. In a sense, islands are conservancies and windows into the past – time capsules that ignite our imagination.

Ireland’s islands appeal to travellers who love nature and traditional Irish way of life. Experience a different perspective of Ireland, from ancient monastic sites and traditional Irish-speaking communities to awe-inspiring creations from both Mother Nature and man which stand the test of time.

Garnish Island
County Cork

Garnish Island Ireland Walk Hike Bike

Just off the southern coast of the Beara Peninsula in Bantry Bay lies the magical garden island of Garnish. Previously inhabited by the distinguished Bryce Family, Annan and Violet Bryce, this rocky outcropping was transformed into one of Europe’s most famous gardens in the early 1900s.

With the help and vision of landscape architect Harold Peto, Garnish Island was quite literally “garnished” with whimsical gardens of exotic plants, walkways, terraces, lawns and beautifully designed buildings, including an Italian Garden, Clock Tower, wisteria engulfed Casita (or Tea House), Grecian Temple and Bryce residence.

The gardens opened to the public in 1925 and have remained a popular destination ever since for both locals and international travellers alike. Enjoy a coffee or snack at the landing pier before starting your leisurely stroll through the grounds, which generally takes about 90 minutes.

HOW TO VISIT: A day tour to Garnish Island may be added to any Beara Way Hike. Access Garnish from Glengarriff Bay by small ferry or water bus (15-min crossing).

When exploring County Kerry, one island not to miss is the dramatic twin-pinnacled crag of Skellig Michael off the Iveragh Peninsula. Rising from the wild Atlantic Ocean and breathtaking in appearance, this ancient Gaelic island monastery dating back to the 6th century was home to the monks of St Fionan for more than 600 years. Following the monks’ departure from the island in the thirteenth century, Skellig Michael became destination for Catholic pilgrimages.

At first glance, this remarkable UNESCO World Heritage Site may feel reminiscent of Peru’s Machu Picchu or the abbey of Mont-Saint-Michel north of Normandy, France. Or, you may recognize Skellig Michael from the Star Wars films, The Force Awakens and The Last Jedi.

Climb the 618 precarious stone steps to the monks’ well-preserved beehive shaped huts and enjoy sweeping views of the rugged Atlantic Ocean and spectacular Ring of Kerry.

The Blasket Islands are a group of six islands off the tip of the Dingle Peninsula which mark the most westerly point in Europe. Great Blasket Island, the largest in the group, hosts an abundance of wildlife and was the source of and inspiration for a number of traditional Irish poems and literature. Although the population never exceeded 176, the islanders were prolific writers and produced over 50 literary works. Due to the harsh living conditions, however, the island was abandoned in 1953.

Soak up the spectacular views from the village ruins or walk the moderate to strenuous 13-kilometre trail around the island, keeping your eyes peeled for Gray seals, dolphins, sharks, Minke whales, Gannets, Puffins and Shearwaters.
