Boylagh

Overview

Boylagh lies on the far north‑west of County Donegal, bordered by the Atlantic Ocean to the north and west and flanked by the baronies of Kilmacrenan, Raphoe South and Banagh. Covering roughly 637 km² (246 sq mi), the landscape is a patchwork of granite uplands, dark peat soils, scattered loughlets and a jagged coastline broken into countless peninsulas, bays and inlets. The barony includes the famed Rosses district, twelve inhabited islands – the largest being Arranmore (Árainn Mhór) – and a string of villages such as Dungloe, Glenties, Annagry and Portnoo.

Geography & Landscape

The western part of Boylagh is dominated by a granite plain that slopes gently towards the sea, creating dramatic sea‑cliffs and sandy bays such as Dungloe Bay and Tyrenagh Bay. Inland, the Bluestack Mountains rise sharply, offering the highest summit in the barony – Crovehy at 1,033 ft – and a network of glens that carve the peat‑rich uplands. The coastline is highly indented; each inlet often hosts a small harbour or a fishing village, giving the area a sense of endless discovery. The twelve inhabited islands, together with numerous islets, provide habitats for seabirds, seals and, in summer, the occasional dolphin.

History

The name Boylagh (Irish: Baollaigh) comes from the ancient territory of the O’Boyles, a Gaelic clan that dominated the area for centuries. In 1791 the Parliament of Ireland formally split the former barony of Boylagh and Banagh, creating Boylagh as a separate civil division. The 1846 Parliamentary Gazetteer described the barony as a “wild and dreary tract” of granite and peat, noting the modest size of Dungloe and the agricultural character of the eastern uplands.

During the early‑17th‑century Plantation of Ulster, the precinct of Boylagh and Banagh was allocated to Scottish undertakers. Scottish families settled in several coastal villages, most notably around Killybegs and Dungloe, leaving a legacy of Gaelic‑Scottish cultural links that can still be heard in the local dialect and music traditions.

Civil Parishes & Townlands

Boylagh contains four civil parishes:

• Inishkeel (partly shared with Banagh) – 127 townlands
• Killybegs Lower (partly shared with Banagh) – 36 townlands
• Lettermacaward – 22 townlands
• Templecrone – 116 townlands

In total, the barony comprises 274 recognised townlands, representing 99.8 % of its area. This granular division is useful for walkers tracing historic routes and for genealogists tracing family landholdings.

What to See & Do

Coastal Villages and Towns

• Dungloe – the principal market town, offering a harbour, traditional pubs and a gateway to the surrounding islands.
• Glenties – nestled at the foot of the Bluestack Mountains, it serves as a launch point for several hill‑walking routes.
• Portnoo and Annagry – picturesque fishing villages with colourful harbour fronts and easy access to the Atlantic surf.

Islands

• Arranmore (Árainn Mhór) – Ireland’s largest inhabited island, reachable by ferry from Burtonport. The island boasts a network of marked trails, including the Arranmore Island Loop (19.4 km, difficult) that traverses coastal cliffs, heathland and historic stone walls.
• Tory Island (Oileán Thoraí) – the northernmost inhabited island, known for its strong Irish‑language tradition and dramatic sea‑cliffs. The Tory Island Trail (11 km, easy) offers panoramic ocean views and a glimpse of traditional thatched cottages.
• Inishkeel – an early Christian monastic site with ancient stone ruins, accessible by a short boat trip from the mainland.
• Smaller islands such as Ranafast and Inishbofin provide quiet spots for bird‑watching and coastal walks.

Mountain and Hill Walks

These routes showcase the barony’s rugged terrain, from the granite peaks of the Bluestack Mountains to the deep, glacial‑carved valleys of the Poisoned Glen. Hikers will encounter heather‑covered moorlands, clear‑water loughs and, on clear days, sweeping vistas of the Atlantic.

Flora, Fauna & Wildlife

The peat‑rich uplands support a mosaic of heather, gorse and native grasses, while the coastal cliffs provide nesting sites for puffins, guillemots and razorbills. In the summer, the bays and estuaries attract oystercatchers, curlews and waders. Seal colonies can be spotted from the islands, and occasional dolphin sightings are reported off the western coast. Bird‑watchers often base themselves in Glenties or Dungloe to explore the coastal trails.

Cultural Highlights

• Gaelic heritage – many villages, especially on the islands, retain Irish‑language signage and traditional music sessions in local pubs.
• Freeholder registers (1829‑31) – detailed records of landholders are available online and are a valuable resource for family historians tracing ancestors in Boylagh.

Practical Information

Boylagh is a largely open landscape; there is no admission fee for any of its natural attractions. The region is served by a network of regional roads linking the villages to the N56 coastal route.

• Parking – free car parks are available at most trailheads (e.g., the Poisoned Glen car park, Glenties village car park). Spaces can fill quickly in July and August, so early arrival is advisable.
• Ferry services – operate from Burtonport to Arranmore (seasonal timetable) and from Dungloe to nearby islands; schedules are published on the Transport for Donegal website.
• Walking maps – detailed OS maps and downloadable GPX tracks are available via the outdoor‑activity platform:
  • Arranmore Island Loop
  • Tory Island Trail
  • Poisoned Glen Walk
• Cycling – the quiet country roads between Glenties, Dungloe and Portnoo are popular with road cyclists; the Bluestack Mountains also offer challenging mountain‑bike routes.
• Accommodation – a range of B&Bs, guesthouses and self‑catering cottages are scattered across the villages; many are family‑run and provide home‑cooked Irish meals.
• Accessibility – most village centres are wheelchair‑friendly, but many of the coastal trails and island paths are uneven and not suitable for strollers.

For detailed maps and downloadable GPX tracks, the outdoor‑activity platform provides an interactive map of the Boylagh Coast and individual route pages:

• Arranmore Island Loop
• Tory Island Trail
• Poisoned Glen Walk
