33 Hidden Gems: The Ultimate Guide to Ireland’s Islands

Scattered like emeralds across Ireland’s wild coastline lie some of Europe’s most untouched treasures – the Irish islands. While millions flock to Dublin’s busy streets and the Cliffs of Moher’s towering heights, these remote havens guard secrets that most travelers never discover: sixth-century monasteries perched on rocky cliffs, pristine beaches without a footprint in sight, and communities where ancient Gaelic still echoes through village lanes.

From Rathlin’s puffin colonies in the north to Cape Clear’s whale-watching waters in the south, Ireland’s 80 offshore islands offer adventures that can’t be found on the mainland. Only 20 of these islands are inhabited, each preserving a way of life that has nearly vanished from the modern world. Whether you’re seeking spiritual solitude in early Christian ruins, yearning to hear traditional music in a local pub, or hoping to spot dolphins from windswept cliffs, Ireland’s islands promise experiences that will stir your soul.

Irish Islands list

Northern Coast – County Antrim, Rathlin Island

Moving northward a little you will find the only inhabited island in Northern Ireland in County Antrim, and one of my personal favourites. There are several lake islands in Northern Ireland including Devenish and Boa Island where you will find the ancient Janus Head. Rough Island which is accessible at low-tide, provides magnificent views of Strangford Lough and is an excellent view point for bird watching.

The Experience:
Head up to Ballycastle Northern Ireland where you can take the ferry across to Rathlin. This is the place to find puffins in season and Rathlin is known to have the largest seabird colony in N. Ireland. Bert’s bus will take you straight from the ferry to the seabird centre where you can observe many after heading down the multitude of steps to the upside-down lighthouse.

The island is home to several reportedly haunted locations, including the Manor House and the ruins of Bruce’s Castle.
