Achill Island – Annagh Lough Woods

📍 County Mayo, Mayo

🏛️ Attraction

Last updated: 28 April 2026

Overview

Achill Island, Ireland’s largest offshore island, stretches over 36,500 acres off County Mayo’s rugged west coast. Linked to the mainland by the historic Michael Davitt Bridge, the island is a cornerstone of the Wild Atlantic Way, boasting towering sea cliffs, five Blue Flag beaches, peat‑covered hills and a scattering of Gaelic‑speaking villages such as Achill Sound, Keel, Dooagh and Dugort. On its western fringe lies Annagh Lough Woods, a tranquil mixed‑species woodland that fringes Annagh Lough – the lowest corrie lake in Ireland, sitting just 15 m above sea level.

History & Cultural Context

Human activity on Achill dates back to the Neolithic, when early farmers cleared forest and erected megalithic tombs on the slopes of Slievemore. Subsequent centuries left a legacy of Iron Age promontory forts and the 15th‑century tower house of Grace O’Malley (Kildownet Castle). In the 19th century the Anglican Rev Edward Nangle founded the Achill Mission at Dugort, whose ruins – including a Franciscan monastery and historic cemetery – still dot the landscape.

The island’s name may derive from the Gaelic acaill (eagle), a nod to the golden and white‑tailed sea eagles that once nested on the high peaks of Croaghaun and Slievemore. While the last resident eagle was recorded in 1912, the cliffs continue to attract raptors such as peregrine falcons and choughs.

Achill is part of the Gaeltacht, so Irish is still spoken alongside English in many communities. The island’s dramatic scenery has inspired artists and writers, and it featured in the 2022 film The Banshees of Inisherin.

Visitor Centre & Aquarium

Achill’s visitor centre, located in Achill Sound, provides maps, local craft displays and information on guided walks. The centre also houses Mayo’s first public aquarium, showcasing native Atlantic fish species and offering an indoor attraction for families on rainy days.

  • Cycling – The Achill‑to‑Westport Greenway (43.5 km) was extended in 2024 with a new 5 km stretch from Achill Sound to Cashel, with plans to reach Keel.

Cycling & the Great Western Greenway

While the Great Western Greenway does not loop around the island, its western terminus at Achill Sound connects cyclists to a traffic‑free 43.5 km trail that runs to Westport. The route follows the former railway, passing through Mulranny’s dunes and offering spectacular coastal views. Bike hire is available in Mulranny and Achill Sound.

Atlantic Drive Scenic Route

The designated Atlantic Drive circles the island (≈ 55 km) and links the island’s natural and historic highlights. Key stops include:

Walking Loops & Trails

Achill offers three marked looped walking routes ranging from 12 km to 44 km, linking coastal paths, inland woodlands and mountain tracks. The Annagh Lough Loop is a gentle 2‑km circuit around the lake, ideal for families and birdwatchers. Longer loops can be combined with sections of the Great Western Greenway for a full‑day hike.

Natural Highlights
