Overview
Templehouse Lake (Irish: Loch Templaig) sits on the southern edge of County Sligo, roughly a 20-minute drive from Sligo town. Covering about 200 acres, this freshwater body forms a natural bend in the Owenmore River, stretching approximately 2 km north-to-south and 500 m east-to-west. The clear, hard-water surface is framed by the rolling pastures of the Templehouse demesne, creating a quiet backdrop for both outdoor recreation and quiet observation. While the surrounding grounds belong to a private estate, the lake remains accessible to visitors through scheduled water-sport sessions, angling, and designated walking routes.
History & The Crannogs
The most striking feature of Templehouse Lake is the cluster of crannogs scattered across its surface. These artificial islands were constructed during the Iron Age, typically by piling stones and timber into the lakebed and covering them with soil. They served as fortified dwellings or seasonal retreats for early Irish communities, offering both security and a steady supply of fish and waterfowl. Though their exact origins are shrouded in time, their presence marks the lake as a site of continuous human activity for over two millennia.
The shoreline history runs just as deep. The earliest recorded structure near the water is a rectangular, keepless hall-house dating to the late 13th century. First mentioned in 1271 after being damaged by Hugh O’Connor, the surviving ruins measure 22 m × 12 m and feature a distinctive sloping batter at the base – a clear indicator of medieval Irish military architecture rather than a Knights Templar foundation, despite the estate’s later name. Later modifications added segmental vaulting to the ground floor and several window embrasures, while an early medieval high-cross base nearby suggests religious activity predating the 1200s.
Ownership shifted through the Knights Hospitaller and eventually to the Perceval family in the 17th century. The Georgian manor house, reconstructed around 1825, now overlooks both the lake and the medieval ruins, creating a visible timeline of Irish architectural history from a single vantage point.
Wildlife & Conservation
Templehouse Lake is designated as part of the Templehouse and Cloonacleigha Loughs Special Area of Conservation (SAC), a status that reflects its ecological importance. The waters support a healthy coarse fishery, including roach, perch, pike, bream, rudd, hybrids, and the critically endangered European eel.
Birdlife is equally diverse. Winter months bring teal, wigeon, goldeneye, mallard, and tufted duck, while mute swans and great crested grebes utilise the reed-lined margins for nesting. The lake has also attracted occasional rare visitors in recent years, including Bridled Tern, Hoopoe, Ferruginous Duck, Black-crowned Night Heron, and Lesser Yellowlegs. Because of its SAC designation, visitors are asked to keep noise levels low, avoid feeding wildlife, and stay on marked paths to minimise disturbance to nesting and wintering species.
Activities
Paddling & Rowing
The estate’s boathouse, run by Wild Wet Adventures, offers guided water-sport sessions on the lake. Stand-up paddleboarding, kayaking, and Canadian canoeing are available in 1 hour 30 minute slots, with prices ranging from €35 to €55 per adult depending on group size and instruction level. All sessions include safety gear and a briefing from qualified guides. The sheltered waters make it a reliable option for beginners, while the calm conditions also suit experienced paddlers looking to explore the shoreline quietly. Visitors can also arrange short rowing boat hires through the boathouse, which provides a relaxed way to photograph the crannogs and ruins from the water.
Angling
Coarse fishing on the lake is free and open year-round. Anglers must carry a valid Irish fishing licence and adhere to the local ban on using live bait for pike. Common catches include pike, perch, roach, bream, rudd, and eel. There are no additional day fees, making it a cost-effective option for anglers visiting the region.
Walking & Birdwatching
A well-marked footpath runs along the northern shoreline, covering approximately 2 km. The trail offers close views of the crannogs, the medieval hall-house ruins, and the high-cross base. The route is suitable for most walkers, though gravel and uneven ground may pose challenges for wheelchairs or pushchairs. For birdwatchers, early mornings and winter months yield the best sightings. A pair of binoculars and a field guide will help identify the resident and migratory species that utilise the SAC habitat.
Practical Information

- Booking: Water-sport sessions require advance booking, particularly in summer. Contact the estate directly at +353 86 7222750 or use the online form on the Templehouse website.
- Accessibility: Shoreline paths and historic ruins are accessed via gravel and uneven terrain. Contact the estate ahead of your visit to discuss specific mobility requirements.
- Conservation etiquette: As an SAC site, please keep dogs on leads, take all litter home, maintain low boat speeds, and avoid stepping on reed beds or disturbing wildlife.

Book water-sport sessions at least a week in advance during July and August, as the estate limits daily participants to protect the lake’s ecology.
