Overview
Achill Island is Ireland's largest offshore island, connected by bridge to County Mayo. It offers wild Atlantic scenery without the crowds of more famous destinations—sea cliffs, empty beaches, and the haunting ruins of Slievemore's deserted famine village.

Before you go
Accommodation
Keel and Dooagh have the most accommodation options near beaches and hiking. Keel Camping opens April-September. Achill Sound has mid-range B&Bs. Many places close in winter.
Connectivity
Mobile coverage is limited to 5G from Eir (Keel) and Vodafone (Bunacurry) on the main road. No signal from Three. WiFi available at most accommodation but don't rely on mobile data in remote areas.
Shopping
Sweeney's SuperValu in Achill Sound is the main local supermarket (M-Sa 8AM-8PM, Su 8AM-7PM). For major shopping, stock up in Westport or Castlebar before heading to the island.
Transport
The island is reached by road via Michael Davitt Bridge from Mulranny. Bus Éireann 450 runs M-Sa every 2-3 hours from Westport across the island, with only three Sunday buses. A car or bicycle is essential for independent exploration.
Weather
Achill's exposed Atlantic position means cool, changeable weather year-round. Summer highs reach 15-20°C; winter brings storms and closures. Pack layers, waterproofs, and be prepared for rapid weather changes.
