Achill Island

Achill Island is a large island off the coast of County Mayo on Ireland’s west coast and is linked to the mainland by a bridge. It is known for a varied shoreline of beaches, bays and steep western cliffs, and for rural landscapes used for farming and recreation.

Coastal highlights include sheltered sandy bays that attract swimmers and family visitors, while the island’s western side offers steep cliffs and long-distance walking routes for experienced hikers. There are also archaeological sites and historic rural settlements that illustrate long-term habitation patterns.

The island has a history of human settlement extending back to prehistoric times and retains evidence of 19th- and early 20th-century rural communities, including abandoned villages and vernacular stone architecture. Cultural heritage and traditional land use remain visible across the island.

Achill lies off the west coast of County Mayo in Connacht, facing the Atlantic. The island’s road connection makes it accessible by car from nearby mainland towns and regional roads.

• Access: Vehicle access to the island is via a bridge from the mainland, making it one of the more easily reached large Irish islands for day visitors and longer stays.
• Best time to visit: Low-season weather can be changeable; summer months offer the most reliable conditions for coastal walking, swimming and cliff viewpoints.
