Overview
Clare Island (Irish: Oileán Chliara) sits four miles off the west Mayo coast, dominating the entrance to Clew Bay. Stretching about 8 km long and 5 km wide, it is the largest of Mayo’s offshore islands. Roughly 130 people call the island home year-round, maintaining a tight-knit community that welcomes visitors eager to explore sea-cliffs, alpine flora, and the legacy of the 16th-century pirate queen Grace O’Malley.
The island offers a rare concentration of heritage sites, from Neolithic settlements to a Cistercian abbey with Ireland’s finest medieval frescoes. A daily ferry connects the island to the mainland, making it accessible for day trips, though many visitors choose to stay overnight in the island’s unique lighthouse accommodation.
Getting to Clare Island
Access to the island is via the Westport Ferry Service, which operates a daily crossing from Roonagh Pier, located near Louisburgh. The journey takes approximately 20 minutes.
- Booking: Advance booking is highly recommended, especially during July and August when demand peaks.
- Timetables: Schedules vary seasonally. Check the ferry operator’s website before planning your trip to ensure you catch the return crossing.
- The Crossing: The short ride offers immediate views of the island’s dramatic cliffs and the surrounding waters. Arriving early on the day of your crossing helps secure a spot on the ferry.
Clare Island Abbey & The Frescoes
The spiritual and historical heart of the island is Clare Island Abbey (St Brigid’s Abbey), a Cistercian foundation rebuilt around 1460. Managed by the Office of Public Works, the ruined abbey is home to Ireland’s most intact suite of medieval frescoes found in any Cistercian church.
The paintings are vivid and unusual for the period. Look closely at the walls and ceilings to spot:
- A dragon perched above the nave.
- A cockerel guarding a window.
- A lively cattle-raid tableau.
- A harper and various stags.
Tradition holds that Grace O’Malley was baptised, married, and buried here. Her canopy-topped stone tomb sits prominently in the nave, marked by a plaque displaying the O’Malley family motto Terra Mariq Pot.
The abbey is open year-round. In summer (May–September), staff are on site to assist visitors. During winter, entry is arranged via the local post-office/shop (open 8 am–5 pm). Photography without flash is permitted, but visitors should respect the fragile nature of the paintings.
Granuaile’s Castle & Prehistoric Monuments
To the east, Granuaile’s Castle stands as a 16th-century tower house overlooking the harbour. Interpretive panels at the site explain its role in the O’Malley clan’s maritime activities and the island’s turbulent medieval history.
Beyond the medieval era, the island holds deep prehistoric roots. The Archaeological Trail is a way-marked route linking 53 Bronze-Age burial mounds, fulachta fiadh (ancient cooking pits), and remnants of a Neolithic settlement. This trail offers a tangible connection to the island’s earliest inhabitants, long before the arrival of the pirate queens. A Napoleonic signal tower, erected in 1804 on the western point, adds a later military layer to the landscape.
The island also played a key role in early scientific study. The Clare Island Survey (1909–1911) produced a benchmark biological record of the island’s flora and fauna that is still cited in modern climate-change research.
The Lighthouse & Boutique Retreat
On the island’s northern tip stands the Clare Island Lighthouse, commissioned in 1806 by the Marquess of Sligo. After a fire in 1813, the present twin-tower lantern was completed in 1818. The lighthouse was decommissioned in 1965 and transformed in 2008 into a boutique bed-and-breakfast.
- Staying at the Lighthouse: The guesthouse offers six individually decorated rooms in the former keeper’s residence. Features include cast-iron beds, flagstone floors, wood-burning stoves, and modern comforts like under-floor heating and Wi-Fi. There are no televisions, allowing guests to focus on the 360° sea views of Achill Island, Westport and the Mayo coastline.
- Day Visits: Non-guests can often climb the tower for panoramic photographs and view the on-site interpretive display about the lighthouse’s engineering. Advance request is recommended for tower access.
Nature & Walking
Clare Island’s micro-climate supports a unique variety of alpine-type flora, making it a destination for botanists and nature lovers. The coastal cliffs and sandy bays provide spectacular walking routes, though the terrain can be uneven and requires sturdy footwear.
The island is a significant stopover for migratory seabirds. Bring binoculars to spot wildlife along the cliffs. The nearby uninhabited Bartragh Island is a short boat ride away, offering additional coastal walks and seabird watching opportunities for those with extra time.
