Overview
Lissagriffin Lakes sit quietly on a low-lying causeway just east of Barleycove beach on the Mizen Peninsula, County Cork. The site consists of two shallow, brackish basins separated by a narrow strip of land that carries the public road between Barleycove and Mizen Head. Fed by local drainage and occasional tidal surges, the waters are ringed by dense reed beds and marsh grasses that create a calm, reflective surface. Because the causeway sits at a slight elevation, it offers uninterrupted views across Dunmanus Bay to the Sheep’s Head Peninsula, making it a natural visual pause for anyone driving the Wild Atlantic Way loop.
History & Landscape
The causeway that now divides the lakes follows the route of an old “butter road” used in earlier centuries to transport goods from the interior farms to coastal ports. While the exact origins of the lakes are tied to natural drainage patterns and historical land management, the surrounding countryside carries deep historical roots. The area falls within the traditional territory of the O’Mahony clan, who held numerous small strongholds along the southwest coast. Local tradition and older field surveys have noted traces of medieval activity in the vicinity, including references to a fortified site nearby, though no visible stonework remains today. The flat, reclaimed landscape around the lakes is a reminder of how generations of farmers shaped this coastal fringe, balancing wetland management with agriculture.
Birdwatching & Nature
The brackish waters and dense reed margins make Lissagriffin a reliable stop for migratory birds travelling along the western seaboard. The wetland habitat supports a steady turnover of waders, wildfowl, and raptors, particularly during the autumn migration window. Visitors with an interest in ornithology will find the lakes especially rewarding from late August through November, when passing flocks use the calm waters to rest and feed.
Key species to look for include:
- Waders & Shorebirds: Snipe, curlew, and various sandpipers that favour the soft, muddy margins.
- Wildfowl: Teal, shelduck, and occasional pintail that patrol the open water.
- Raptors & Gulls: Kestrels and peregrines that hunt over the marshes, alongside common and lesser black-backed gulls.
- Terrestrial Birds: Reed warblers and sedge warblers that nest in the dense vegetation during summer.
The site is quiet enough to hear flight calls on still evenings, and the lack of heavy foot traffic means birds are generally undisturbed. Binoculars and patience will go a long way here.
Walks & Photography
A short, flat stroll along the causeway offers one of the most relaxed coastal walks on the peninsula. The paved surface is level and suitable for most wheelchairs and pushchairs, though visitors should note that the road is an active public route with passing traffic. Photographers are drawn to the lakes at dawn and dusk, when low light catches the reed beds and the water mirrors the sky. The open sightlines toward the bay and the distant cliffs provide a clean, uncluttered frame, while the seasonal change in water levels creates shifting reflections that keep the scene interesting year-round.
Practical Information
- Access & Admission: The lakes are freely accessible from the public road. There are no entry fees, ticket offices, or formal visitor facilities.
- Parking: Free parking is available in the lay-by at Barleycove. During peak summer months, the lay-by can fill quickly, so arriving early or mid-week is recommended.
- Best Time to Visit: Early morning or late afternoon offers the calmest conditions for wildlife viewing and photography. Autumn (September–November) is the peak season for migratory birds.
- What to Bring: Comfortable walking shoes, a light jacket (coastal winds can be brisk), binoculars, and a field guide or birding app. The site is not fenced, so keep dogs on a short lead to avoid disturbing nesting or roosting birds.
- Getting There: From Cork City, take the N71 west to Bantry, then follow the R595 to Schull. Continue west on the R595 toward Mizen Head; the causeway crossing the lakes appears shortly after the turn-off for Barleycove. A rental car is strongly recommended for navigating the Mizen Ring, as public transport options in this area are limited.
Nearby Attractions
Lissagriffin Lakes sit at a convenient crossroads on the Mizen Peninsula, making it easy to combine a stop here with several other regional highlights:
- Barleycove Beach – A wide, sandy beach backed by protected dunes. It’s a Blue Flag site popular for swimming, surfing, and coastal walks.
- Mizen Head Visitor Centre – Features the historic Irish Light Signal Station and the famous arched bridge connecting the headland to the mainland.
- Three Castle Head – Three 15th-century tower houses clustered beside a cliff-top lake. Access is currently restricted for safety, but the exterior views from the road remain striking.
- Dunmanus Castle – A well-preserved medieval tower house overlooking the bay, offering guided tours and panoramic coastal views.
- Brow Head – The southernmost point of mainland Ireland, featuring scenic cliff walks and the 19th-century Brow Head Signal Tower.
- Altar Dolmen & Altar Church – Located near the road to Toormore, this site pairs a Neolithic dolmen with a 19th-century famine-relief church, with a Bronze Age wedge tomb discovered nearby.
For the best experience, plan your visit around low tide if you intend to walk the adjacent marsh edges, and always check local road conditions after heavy rain, as the causeway can experience minor flooding. The lakes are at their quietest on weekday mornings, making it an ideal spot to step away from the busier coastal attractions and watch the light shift over Dunmanus Bay.
