Overview
Annagh Lough Woods lie on the rugged western side of Achill Island, County Mayo. The woods fringe Annagh Lough – a tiny corrie lake perched just 15 m above sea level, making it the lowest such lake in Ireland. The setting is a blend of glacially‑carved terrain, wind‑blown sand plains (machair) and the dramatic cliffs of Croaghaun that rise nearby. Visitors are drawn by the quiet atmosphere, the chance to spot rare Arctic‑alpine flora such as juniper, and the sweeping views over the Atlantic that frame the landscape.
History
While much of Achill is dominated by open peat‑bog and coastal scrub, the Annagh Lough Woods are a relatively recent addition. In the latter half of the 20th century, the Curraun Peninsula saw a programme of commercial forestry and community‑led planting, creating the mixed‑species woodland that now cushions the lake. The woods are managed as a wildlife reserve, preserving native birch, hazel and ash while encouraging the re‑establishment of rare alpine plants.
Flora & Fauna
- Arctic‑alpine plants – Juniper (Juniperus communis) is the most notable, thriving on the limestone outcrops that fringe the lake. In late spring the surrounding heather and wildflowers add colour to the landscape.
- Birdlife – The cliffs of Croaghaun attract choughs, golden plovers and peregrine falcons. Early mornings often bring the distant call of these raptors, and occasional winter visitors include merlins and barn owls.
- Mammals & Insects – The mixed woodland supports red squirrels, hares and a variety of butterflies, especially in the summer months when the understory is in full bloom.
What to See & Do
- Walk the Annagh Lough Loop – A gentle, well‑marked trail circles the lake, weaving through mixed‑species woodland. The path is largely even‑grounded with a few natural stone steps, making it suitable for most walkers. Exact loop length is currently unconfirmed.
- Flora Spotting – Keep an eye out for juniper and other alpine plants on the limestone outcrops. The woodland itself is a mosaic of native birch, hazel and ash, interspersed with heather that blankets much of Achill’s peatlands.
- Birdwatching – Early mornings are ideal for listening to the calls of choughs and spotting peregrine falcons soaring over the cliffs. While eagles are no longer resident, the surrounding heights still attract raptors during migration.
- Machair Exploration – A short detour from the woods leads to the machair at Keel, where wind‑blown sand plains host a range of wildflowers and provide a unique coastal habitat.
- Connect to the Loop Walk Network – The Annagh Lough Woods form part of a broader network of walking routes that link Achill’s coastal paths with inland trails. Hikers can extend their journey to nearby loops such as the Ballycroy‑National‑Park trail system.
