Overview
Achill Island is Ireland’s largest offshore island, stretching over 36,500 acres off the west coast of County Mayo. Linked to the mainland by the swing‑bridge Michael Davitt Bridge (opened 1887), the island is a cornerstone of the Wild Atlantic Way, offering dramatic sea cliffs, five Blue Flag beaches, peat‑covered hills and a scattering of historic villages such as Achill Sound, Keel, Dooagh and Dugort. The island’s population of roughly 2,300 lives in a vibrant Gaeltacht community where Irish and English intertwine.
History
Human presence on Achill dates back to the Neolithic (c. 4000 BC), when early farmers cleared forest and erected megalithic tombs on the slopes of Slievemore. The Iron Age left a network of promontory forts, and the 15th‑century tower house of Carrickkildavnet (often called Grace O’Malley’s Castle) testifies to the power of the O’Malley seafaring clan. In the 19th century the Anglican Rev Edward Nangle founded the Achill Mission at Dugort, a controversial “Colony” that combined schools, an orphanage and a guesthouse. The mission’s legacy is still visible in the ruins of the Franciscan monastery at Bunnacurry and the historic cemetery at Kildamhnait.
The island’s more recent cultural imprint includes the painters Paul Henry and Eva O’Flaherty, whose early‑20th‑century canvases captured Achill’s light. Film crews have also been drawn here: The Banshees of Inisherin (2023) used Keem Bay, Cloughmore and other locations, while My Sailor, My Love filmed on the island’s rugged coast.
What to See & Do
Natural Highlights
- Croaghaun Cliffs – at 688 m they are the highest sea cliffs in Ireland and the third highest in Europe. The climb from Keem Bay is strenuous but rewards hikers with sheer drops and occasional peregrine sightings.
- Slievemore (671 m) – the island’s highest peak offers several walking routes, including a trail that passes the haunting Deserted Village, a collection of 80‑100 stone cottages abandoned after the 1845 famine.
- Minaun Heights – a short drive up a narrow road provides panoramic views of Keel, Keem Bay and the surrounding Atlantic.
- Ashleam Bay – a pebble cove framed by 30‑metre white cliffs, marked as a Wild Atlantic Way Discovery Point.
