About Achill Island

Learn more about the host city, Achill Island.

Achill Island is an island just off the coast of County Mayo in the west of Ireland, linked by a bridge to the mainland. It's Ireland's largest island, with some farming but mostly uncultivated heath and hills. The two main settlements are Achill Sound by the bridge and Keel straggling into Dooagh near the west tip; in 2022 its population was 2350. Everyone speaks English but many residents are Irish speakers, especially on the east side of the island.
