Achill Island
Achill is Ireland's largest western island, connected to the mainland since 1887. It features dramatic headlands, historic lighthouses, and a community that blends farming with tourism.
The barony
Erris sits in northwestern County Mayo. It spans over 230,452 acres (932.61 km²), mostly mountainous blanket bog. The west and north borders meet the sea. Belmullet and Bangor Erris are the main towns. The name comes from Irish: “Iar Ros,” which means “western promontory.” The full name is Iorrais Domnann, named after the Fir Bolg tribe, the Fir Domnann. This is the western edge of Mayo. You have the wild Atlantic to the north, the bays of Broadhaven and Sruth Fada Conn, and Blacksod Bay to the west.
The promontories
The coast breaks into several headlands. The Doohoma Peninsula, the Mullet Peninsula, Erris Head, the Dún Chiortáin and Dún Chaocháin peninsulas, and Benwee Head define the shape. The Mullet is the largest. The Wild Atlantic Way runs through this country at its wildest. Blanket bog, headlands, and bays dominate the view. Villages tuck into the shelter of the water. Five Catholic parishes cover the area: Kilcommon, Kilmore, Kiltane, Belmullet, and Ballycroy. These parish areas represent the older history of the barony.
The Gaeltacht
Parts of Erris fall within a Gaeltacht area. First-language Irish speakers live in An Fál Mór, Tamhain na hUltaí, Glais, and surrounding townlands. This is the Irish-speaking heart of the barony. It is where the Mayo Gaeltacht meets the Atlantic. Walking through these villages usually happens before tackling the headlands. The sign on the gate marks the boundary clearly.
Practical
You can drive to Erris from Westport and Castlebar. The barony is big. One day isn’t enough. Spend a day on the Mullet. Use another for the bays. Visit the villages in between. Belmullet and Bangor Erris work as bases. Weather on the headlands dictates the pace.
