Overview
Lough Atedaun (Irish: Loch Áiteadún) is a modest‑sized freshwater lake set in the iconic karst terrain of the Burren, County Clare. Measuring roughly 1 km long by 0.6 km wide, the lake lies about 5 km north of Ennis and a short distance east of the village of Corofin. Its waters are fed by the River Fergus, which arrives from the neighbouring Lough Inchiquin, and the lake drains back into the Fergus, creating a gentle riverine corridor that threads through the limestone pavement.
The lake sits at an elevation of 15 m above sea level and forms part of the East Burren Complex Special Area of Conservation (SAC) as well as the Corofin Wetlands Special Protection Area (SPA). These designations protect a mosaic of habitats – from the eutrophic lake itself to surrounding grasslands and wetland fringes – making the area a haven for both aquatic life and birdwatchers.
History & Natural Heritage
While Lough Atedaun does not host grand castles or ancient ruins on its immediate shore, its setting is steeped in the geological story of the Burren. The region’s limestone pavements were formed over 350 million years ago, and the lake’s shallow, nutrient‑rich waters have become a key component of the local ecosystem.
Flora & Fauna
- Fish: perch, rudd, pike, stone loach and the critically endangered European eel.
- Birds: wigeon, teal, gadwall, curlew and occasional winter visitors such as the Bufflehead (recorded in February 2024 by BirdWatch Ireland).
- Plants: rare alpine‑type flora thrive on the limestone outcrops protected by the SAC status.
How to Get There
By Car – The most convenient route is via the R476 from Ennis (approximately 15 km). Follow signs for Corofin and then for the Lough Atedaun car parks. Parking is available at the main Corofin car park and at smaller lay‑bys near the trailheads.
Public Transport – Bus services run from Ennis to Kilfenora; from Kilfenora a short taxi or rideshare can bring you to Corofin and the lake. There is no direct bus to the lake itself.
Cycling – The regional road network around Corofin is suitable for hybrid or mountain bikes. Parts of the Burren Way, which passes close to the lake, are popular with cyclists seeking a scenic ride.
Activities

Over 20 marked routes radiate from the lake, ranging from easy family loops to moderate countryside treks. Highlights include:

Fishing
Angling is permitted on Lough Atedaun with a valid Irish fishing licence. The lake holds perch, pike, rudd and stone loach, offering good sport for both novice and experienced anglers. Check local regulations and respect the SAC restrictions, especially during spawning periods.
Cycling
Sections of the Burren Way near the lake are cycle‑friendly, providing a rugged but rewarding ride through limestone pavement and open grassland. Bring a sturdy bike and be prepared for occasional steep sections.
Birdwatching & Wildlife
The lake’s position within a SPA draws waterfowl throughout the year. Early‑morning visits increase the chance of spotting wigeon, teal, curlew and the occasional Bufflehead. Organized outings, such as the BirdWatch Ireland event on 24 February 2024, have recorded these species.
Seasonal Highlights & Tips
- Spring (April–June) – Wildflowers carpet the limestone pavement; bird activity is high.
- Summer – Long daylight hours suit longer hikes; paths can become dry and dusty.
- Autumn (September–October) – Milder temperatures and striking foliage make for pleasant walks.
- Winter – Paths may be wetter; waterproof boots are advisable. Some bird species migrate, offering different viewing opportunities.
