Overview
Lough Eske (Irish: Loch Iasca) is a modest‑sized lake – roughly nine miles of shoreline and depths reaching 100 ft – nestled northeast of Donegal Town. The lake sits in a natural amphitheatre of the Bluestack and Tawnawully Mountains, offering mirror‑like reflections of rugged peaks and ancient woodlands. Its nickname, the “Fisherman’s Haven”, is well earned: the clear, cold waters host spring salmon, sea trout, char and brown trout, making it a magnet for anglers from March through September. Around the lake two luxury hotels, the five‑star Lough Eske Castle Hotel and the four‑star Harvey’s Point, provide upscale bases for exploring the surrounding countryside.
History
The story of Lough Eske is inseparable from the O’Donnell clan, who erected a fortified castle and bawn on Island O’Donnell on the lake’s southern shore in the 15th century. Remnants of that bawn still stand, a silent reminder of the chieftains who once used the island as a prison. After the 1601 burning of the Franciscan friary in Donegal Town, the friars retreated to the lake’s western shore, establishing a new friary that gave its name to the local townland of ‘The Friary’ and the scenic ‘Friar’s Walk’ along the water’s edge.
In the Plantation era the estate passed to Sir Basil Brooke and later to Thomas Young (who became Thomas Brooke) in the early 19th century. Thomas commissioned Christ Church on the southern shore in 1846 and, with architect Fitzgibbon Louch, transformed the existing manor into an Elizabethan‑style residence completed in 1868 – the building that would become Lough Eske Castle.
The castle changed hands in 1894 when Major‑General Henry George White purchased it. After a fire in 1939 the house fell into ruin, but a determined local entrepreneur, Pat Doherty, rescued the shell and oversaw a meticulous restoration that reopened the property as the Solis Lough Eske Castle Hotel in December 2007. Recent developments include the 2024 unveiling of the “Donegal Suites”, 25 new luxury rooms finished in bespoke Magee 1866 tweed, four‑poster beds, roll‑top baths and modern tech.
What to See & Do
Fishing
Lough Eske is a premier salmon and trout fishery. Angling is boat‑only and runs from 1 March to 30 September. Permits are sold at the Eske Angling Centre on the lake’s southwest bank. The lake supports:
| Species | Season |
|---|---|
| Spring salmon | 1 Mar – 30 Sep |
| Sea trout | 1 Mar – 30 Sep |
| Char | 1 Mar – 30 Sep |
| Grilse | Jun – Sep |
| Brown trout | Year‑round (spinning/fly) |
Trolling for shrimp or prawns is prohibited to protect the ecosystem.
Walking, Cycling & Wildlife
The lake’s perimeter is criss‑crossed by a network of paths. A narrow boardwalk on the south‑western shore leads through lush woodland, while the Lough Eske Loop Walk offers a 6 km circuit of forest trails, lakeside viewpoints and a brief ascent to nearby hills. The Bluestack Mountains Way, a 65 km long‑distance trail, passes the lake and provides a dramatic backdrop of the surrounding mountains for multi‑day hikers.
Ardnamona Wood, adjacent to the lake, has newly reconstructed trails suitable for casual strolls or guided bike rides. The estate’s historic high Celtic cross – the grave marker of Major‑General White – sits half a mile from the castle, accessible via a raised wooden walkway that keeps visitors above the boggy ground.
Island Exploration & Heritage
Island O’Donnell still bears the stone bawn, while Roshin Island in the southeast corner is believed to have served as a friary graveyard; visible stone markers hint at its monastic past. The lake’s arch bridge at the southern tip makes a perfect photo spot and offers easy access to the shoreline.
A quirky piece of local folklore is the “Lough Eske Monster”, a 1998 sighting that sparked headlines. Whether myth or mis‑identified seal, the story adds a dash of mystery to evening walks.
Lough Eske Castle Hotel – Luxury, Spa & Dining
The castle hotel blends 15th‑century stonework with contemporary luxury. Guests can join a guided castle history tour to learn about the O’Donnells, the Brooke family and the 20th‑century restoration. The CARA Organic Beauty Spa occupies the footprint of the original Victorian glass house and features:
- An infinity pool with aqua‑green and gold mosaics
- Seven treatment rooms, including two couples’ suites with jet baths
- A fully equipped thermal suite (ice fountain, sauna, steam room, sanarium, tropical showers)
Dining is anchored by Cedars Restaurant, praised for refined Irish and international cuisine, and the more relaxed Gallery Bar serving hearty pub fare with a gourmet twist. Afternoon tea is served daily in the drawing rooms.
