Overview
Lough Gara has more crannógs – man-made prehistoric islands – than any lake in Ireland: somewhere around 300 of them, most of which only came to light when the lake was partly drained in the 1950s. It’s a shallow, reedy basin straddling the border between south County Sligo and County Roscommon, covering 12.57 km² and sitting 66m above sea level. It runs about four miles north to south and widens to two and a half at the centre. Water comes in from the Lung River in the south-west and the Breedoge in the south-east, and leaves to the north-east through a mile-long channel, Lower Lough Gara, before becoming the Boyle River and running on toward Lough Key and the Shannon.
The country around is open farmland, peat bog and the low line of the Curlew Mountains. Boyle and Ballaghaderreen are both a little over four miles off, which makes the lake an easy stop. Come for the birds and the archaeology rather than a swim – this is a lake to walk the edge of and watch, not to plunge into. It’s designated both an Important Bird Area and, since 7 June 1996, a Ramsar wetland of international importance, the protected site covering 1,742 hectares.
The crannógs
Long before its present name the lake was Loch Techet. When the O’Gara clan took control of the Coolavin district in the 13th century it became Loch Uí Ghadhra, the lake of the O’Garas; the first written reference is from 1285, and the name held even after the family lost their lands around 1650.
Its man-made islands are what set it apart. The roughly 300 crannógs here form the greatest concentration in Ireland, and most were exposed by a drainage scheme in the 1950s that dropped the water level and left them standing clear of the shallows. Excavations turned up Iron Age, Bronze Age and early Christian material, but it was the Swedish archaeologist Christina Fredengren’s five-year research programme that reshaped how they’re understood: her work, published as Crannogs (Wordwell), argues that some were built more than two thousand years ago and served less as defensive boltholes than as long-lived community sites, fishing platforms and markers of territory. In Monasteraden, a small fountain monument unveiled in 1999 maps the lake’s outline and remembers the local heritage champion Terry Madden.
Birds and wetland
The reed beds, shallow margins and open water make Lough Gara an important wintering ground for wildfowl. It’s one of the more reliable places in Ireland to see Greenland white-fronted geese, which arrive from the Arctic each autumn, and it holds more than 1% of the world population of whooper swans through the winter. Rarer vagrants turn up too, enough to keep serious birdwatchers checking the flocks. Early morning is best, when the water is still and the birds are feeding along the weed beds; the Ramsar designation keeps the sensitive habitats managed, and there are viewing hides along the shore.
Walking the shoreline
Two options let you take the lake in on foot:
- Lung / Lough Gara Way (45 km): part of the Beara Breifne Way, following the Lung River north, along the eastern shore and past a string of Iron Age ringforts. Walkers can collect passport stamps at set points, including the Portahard Church and interpretive centre, which tells the story of Dr Douglas Hyde, Ireland’s first president.
- Lough Gara Lake & Legends bogland trails: four shorter loops through bog, woodland and lakeside, with signage on the local folklore and the ecology of the bogs. Easy going, and good for families.
Activities at the lake
On the Roscommon shore near Boyle, Lough Gara Country Pursuits is a family-run activity centre run by Jimmy and Adrien Kneale with their daughter Dána. Jimmy Kneale shoots skeet for Ireland and has a world-championship silver to his name, and the centre offers a broad spread of supervised activities:
- Horse riding: AIRE-approved stables with a covered arena, so rides go ahead in any weather, plus a Saturday-morning saddle club and dressage lessons.
- Shooting: clay, air rifle and airsoft ranges with instruction.
- Falconry and archery: bird-of-prey demonstrations and guided archery for all levels.
- Family and group activities: assault courses, gentle boating and a pets corner.
Everything needs booking ahead, and some of it (falconry displays, certain shooting sessions) runs seasonally. Call the centre on +353 86 893 8972. It caters to schools, scout and corporate groups as well as families.
Fishing
Lough Gara fishes well for coarse species and is rated among the region’s better pike waters, with perch, roach and bream along the reed edges and weed beds. Being shallow, it gives up fish to bank and boat alike through the season. Bring a valid Inland Fisheries Ireland licence and check the current rules before you head out; tackle shops in Boyle and Ballaghaderreen carry gear and bait.
Staying nearby
Lough Gara Lodge at Monasteraden offers self-catering with six bedrooms, within walking distance of the village pub and handy for both the trails and the activity centre.
Within a short drive:
- Moygara Castle: the ruins of a 16th/17th-century O’Gara stronghold on the north-western shore, best seen from a distance while conservation work continues.
- Coleman Irish Music Centre: at Gurteen, celebrating the fiddler Michael Coleman and the south Sligo playing style.
- Lough Key Forest Park: zip-line canopy tours, boating and castle ruins.
- Eagles Flying: a bird-of-prey sanctuary with daily displays.
- Boyle: King House, pubs and weekend markets.
Practical information
- Parking: free car parks at the Country Pursuits centre, Clooncunny Bridge and the main N4 lay-by.
- Access: the lake and trails are open year-round; some activity-centre offerings run seasonally.
- Getting there: easiest by car, via the N4 (Boyle) or N5 (Ballaghaderreen); public transport is limited to buses at Boyle and Ballaghaderreen. Nearest airports are Ireland West (Knock, 30 minutes) and Galway (about an hour and a quarter).
- What to bring: boots for the bog trails, binoculars for the birds, and waterproofs.
If you do one thing here, come at first light in winter and walk out to a hide: the geese and swans on the water, with the crannógs breaking the surface behind them, are the whole point of the place.
