Overview
The River Eske (Irish: An Easca) is a short but vibrant waterway that begins its 5km journey at the tranquil waters of Lough Eske in south-eastern County Donegal. Flowing westward through the foothills of the Bluestack Mountains, it picks up the Drumenny Burn near the Community Hospital before carving a scenic route through the historic streets of Donegal Town. Finally, it empties into the expansive waters of Donegal Bay at the town’s harbour.
Despite its modest length, the Eske is a major attraction for both anglers and walkers. Its clear waters support healthy populations of spring salmon, sea trout, char, and brown trout. Beyond sport fishing, the river provides a peaceful promenade for strolls, a series of architecturally interesting bridges that mark the town’s evolution, and a dramatic backdrop for the 15th-century Donegal Castle, which sits proudly on a bend near the river’s mouth.
History & The Bridges of the Eske
Historically, the Eske has been the lifeblood of Donegal Town. Its banks have witnessed the rise of the O’Donnell clan, the construction of Donegal Castle in 1474, and the subsequent English occupation that led to the destruction of the nearby Franciscan Abbey following the Flight of the Earls in 1607.
The river’s bridges tell a parallel story of engineering and community development. Just downstream from the lake lies Lough Eske Bridge, followed by the 19th-century Thrushbank Bridge and a modern concrete span on the N56 bypass. Within the town itself, the river is crossed three times: Kennedy Bridge (erected in 2004 on a crossing site used since the 1830s), the iron Tyrconnell Bridge (originally built in 1895 and substantially rebuilt in 2018–19), and the historic three-arched Bridge Street crossing, which has been listed on the Record of Protected Structures since 2003.
The Lost Six-Arch Bridge
Local history enthusiasts often point to older maps and 19th-century lithographic prints showing a six-arch bridge that once stood just north-east of the current Bridge Street structure. Samuel Lewis’s early-1800s topographical work and the 1837 Ordnance Survey map both document a “tolerable bridge of six arches” carrying the main road behind Donegal Castle. The National Inventory of Architectural Heritage notes that the current three-arch bridge was built around 1855, replacing the earlier six-arch structure after a brief period where both crossings co-existed around 1860.
What to See & Do
Angling
The Eske is widely regarded as one of Ireland’s premier salmon and trout fisheries. The fishing season runs from 1 March to 30 September, with the most productive runs of salmon and sea trout typically occurring during the summer months. Anglers favour specific sections such as Timony’s Turn to the Mill Pool, the stretch below Miss Jenny’s Bridge, and the Eel Weir Turn downstream of Lough Eske Bridge. Both fly-fishing and spinning are popular methods, with traditional flies like the Fiery Brown, Jacob’s Ladder, and Donegal Blue proving highly effective.
A fishing permit is mandatory for all anglers. The river also stands out for its inclusive design, offering wheelchair-friendly access at the Mill Pool, making it one of the most accessible angling sites in the region.
Walking & Heritage
The Bank Walk follows the western bank of the Eske for roughly 2km as it approaches the bay. This tree-lined path is a favourite among locals and visitors alike, dotted with whimsical “fairy doors” that delight children. From the walk, you can glimpse the ruins of the Old Abbey (Donegal Friary) on the opposite bank, founded in 1474, and enjoy sweeping views of Donegal Castle. The path is fully paved near the Mill Pool, providing easy, level access for families and wheelchair users.
Wildlife & Birdwatching
The healthy fish populations attract a diverse range of birdlife along the riverbanks. Kingfishers are frequently spotted darting over the shallows, while grey herons and ospreys patrol the estuary during migration season. Otters have also been reported along quieter stretches, making early-morning walks an excellent opportunity to spot Ireland’s elusive mammals.

Access & Parking The most convenient entry points for walkers are Kennedy Bridge and the Mill Pool area. Anglers often launch from the Mill Pool jetty or designated spots near Miss Jenny’s Bridge. Limited free parking is available beside the Mill Pool and at the Quay Car Park, though visitors should check local alerts as these low-lying areas can be affected during high tides or heavy rain. Paid parking is available on Main Street.
Safety & Environmental Notes The Eske has a history of rising rapidly during heavy rainfall. During the fishing season, particularly after prolonged wet weather, keep an eye on local weather updates and avoid low-lying paths that may become waterlogged. Visitors are also advised to check the Donegal County Council website for any water-quality advisories before planning close-up wildlife walks or swims.
Nearby Attractions After a day on the water, explore the town centre’s vibrant cafés and craft shops, or take a short drive to the historic monastic site at Assaroe. The Bluestack Mountains lie just north of the town, offering extensive hiking trails for those looking to extend their outdoor adventure.
Check the current tide times before visiting the estuary, as low tides reveal fascinating rock pools and better access to the lower river sections for photographers and birdwatchers.
