Overview
Lough Ennell (Irish: Loch Ionnall) sits just south-west of Mullingar in County Westmeath. The lake stretches roughly 5 km in length and 2 km in width, covering about 12 km². Its shallow profile makes it highly accessible: two-thirds of the surface lies under 8 m deep, with nearly half shallower than 5 m. This creates extensive reed beds and wetlands that support a dense population of waterfowl and game fish. The lake forms part of the Lough Ennell Special Protection Area and holds Ramsar wetland status, reflecting its ecological importance.
On the southern shoreline, Jonathan Swift Park provides the main public access point. It features a stony beach, a designated swimming zone, and serves as a trailhead for walkers and cyclists exploring the surrounding countryside.
History & Literary Links
The River Brosna feeds into the lake near Mullingar and flows out towards the village of Lilliput. The area’s name owes its whimsical fame to Jonathan Swift, author of Gulliver’s Travels. Local tradition holds that Swift, travelling by boat, looked back at the tiny houses and fields along the shore and imagined them as the miniature kingdom of Lilliput. The nearby Lilliput House (historically known as “Nure”) later became a recognised literary landmark tied to this tale.
On the northern edge stands Belvedere House, an elegant Georgian mansion now managed by Westmeath County Council. The estate grounds regularly host outdoor concerts, triathlons, and community festivals, creating a natural link between the lake’s quiet landscape and the region’s cultural calendar.
What to See & Do
Angling & Watersports
Lough Ennell is a well-regarded fishery for brown trout and pike. It produced Ireland’s largest officially recorded brown trout, weighing 26 lb (11.8 kg), and remains a favourite for both casual anglers and competitive fly-fishers. The fishery is managed by the Shannon Regional Fisheries Board’s Midland Fisheries Group, which maintains stocking programmes and seasonal regulations.
Small craft hire is available from the historic boathouse on the southern shore. Visitors can rent rowboats, kayaks, and paddleboards for exploring the shallows and reed-lined coves. High-speed motorcraft and jet skis have been restricted for many years to preserve the lake’s calm character, making it ideal for sailing, leisurely paddling, and wildlife observation.
Swimming & Beach
The designated swimming area runs along a stony beach beside the boathouse. The water is shallow near the shore, making it manageable for children, while a deeper channel further out suits confident swimmers. Diving and jumping are strictly prohibited to protect both visitors and the lake’s delicate ecology. Life rings and warning signs are positioned around the perimeter, and the area is regularly patrolled during peak summer weekends.
Walking & Cycling
The Westmeath Way circles the lake’s perimeter, with Jonathan Swift Park acting as a key junction. Stage 1a begins in Mullingar town centre, while Stage 1 and Stage 2 use the park as a southern and northern waypoint respectively. A shorter northern loop near Lilliput offers a moderate alternative for those wanting a shorter out-and-back route.
Cyclists can connect the lake to the Royal Canal Greenway, Ireland’s longest off-road trail. A dedicated 4 km spur links the greenway network to Lough Owel, with Lough Ennell serving as a convenient rest stop and hydration point for long-distance riders.
Golf & Events
Mullingar Golf Club occupies the north-east fringe of the lake, offering a parkland course with several holes playing alongside the water’s edge. The area also hosts annual triathlons and open-water swims, typically staged between Lilliput and Belvedere House. These events draw regional competitors and provide a lively atmosphere for spectators.
Wildlife & Conservation
The lake’s shallow, nutrient-rich margins create ideal breeding and feeding habitat for wetland species. Regular sightings include mute swan, great crested grebe, reed warbler, common moorhen, and the occasional kingfisher. The reed beds also provide cover for otters and water voles, though these mammals are more commonly spotted at dawn or dusk. Birdwatchers tend to visit in spring and autumn to catch migratory passes, while the summer months bring nesting activity along the sheltered coves.
