Overview

Clare Island (Irish: Oileán Chliara) sits at the mouth of Clew Bay, four miles off the west Mayo coastline. At 8 km long and 5 km wide, it is the largest of the Mayo offshore islands and a striking waypoint on the Wild Atlantic Way. The island’s population is just over 130 permanent residents, but the summer months see a lively influx of visitors drawn by its dramatic sea‑cliffs, alpine flora, and the lingering legacy of the 16th‑century pirate queen Grace O’Malley (Granuaile). A single daily ferry links the island to Roonagh Pier near Louisburgh, shaping a rhythm that feels both remote and welcoming.

History

The O’Malley clan ruled the island throughout the Middle Ages. Their imprint is visible in several key sites:

  • Granuaile’s Castle – a 16th‑century tower house perched on the eastern harbour edge, once the stronghold of Grace O’Malley.
  • Clare Island Abbey – a 15th‑century Cistercian abbey on the south coast, famous for rare medieval wall‑paintings and the O’Malley tomb, thought to be the pirate queen’s burial place.
  • Clare Island Lighthouse – erected in 1806 by the Marquess of Sligo, decommissioned in 1965 and now a boutique guesthouse.

The island also bears the scars of wider history: a Spanish Armada ship wrecked in 1588, a Napoleonic signal tower (1804) on the western point, and the extensive Clare Island Survey (1909‑1911) – a pioneering biological study that still informs climate‑change research.

What to See & Do

Heritage Trail

Walk the Archaeological Trail to see 53 Bronze‑Age mounds, fulachta fiadh cooking sites, and the remains of a Neolithic settlement. The trail is way‑marked and passes both Granuaile’s Castle and the Abbey, allowing you to read the island’s story from pre‑history to the pirate era.

Abbey and Castle

The Abbey is open year‑round; in summer it is staffed, while in winter entry is via the local shop. Inside, the medieval wall‑paintings depict dragons, riders and mythic scenes – a rare glimpse of 14th‑century art. Granuaile’s Castle is a quick stop just outside the harbour; although interior access is restricted, the exterior offers dramatic photo opportunities.

Lighthouse Stay

For a unique overnight experience, book a room at the Clare Island Lighthouse. The lighthouse‑keeper’s quarters have been converted into sleek, self‑catering rooms with wood‑burning stoves, Wi‑Fi and sea‑view terraces. No televisions are provided, encouraging a true escape. Reservations are required, especially from May to September.

Walking Loops

Two popular way‑marked loops cater to all fitness levels:

  • Fawnglass Loop (3 km) – starts at the harbour, circles the townland of Fawnglass, and passes Granuaile’s Castle. Takes about an hour.
  • Knocknaveen Loop (8 km) – traverses hills, bogs and the small loughs of Creggan and Leinnapollbruty, climbing to Knockmore (463 m). Expect 2½ hours of varied terrain and panoramic views of Achill, Croagh Patrick and the mainland.

A full circumnavigation of the island is also possible for the ambitious, offering endless cliff‑top vistas and opportunities to spot nesting seabirds such as gannets, puffins and razorbills.

Beach & Water Activities

Clare Island Beach, a blue‑flag sandy stretch beside the harbour, is ideal for a relaxed dip. A sheltered cove on the north‑east side provides a quieter swimming spot, and lifebuoys are available even though there is no lifeguard. For the adventurous, local providers offer coasteering, snorkelling, rock‑climbing and raft‑building excursions from the island’s adventure centre.

Cultural Events

The island hosts several seasonal festivals:

  • Regatta Festival (July) – traditional currach races, tug‑of‑war and an egg‑and‑spoon competition.
  • Bard Summer School (July) – music, poetry and dance celebrating ancient myths.
  • Clare Island Film Festival (September) – short‑film screenings in secret venues.
  • Singles Weekend (late September) – a lively community gathering.

Yoga & Food

Macalla Farm offers yoga and meditation retreats on an organic working farm, with vegetarian cooking courses that use produce grown on‑site. For casual meals, the Clare Island Community Centre & Bar serves hearty pub fare and hosts traditional music sessions. A single shop, O’Malley Foodstore & Post Office, provides basic groceries; cash is essential as there are no ATMs.
