Overview
Raghtin More (Irish: Reachtain Mhór), also known as Slieve Keeroge, rises to 502 metres (1,647 ft) on the western side of the Inishowen Peninsula in County Donegal. It is the highest point in the Urris Hills and ranks 33rd by height and 6th by prominence among Donegal’s 512 summits. From the summit you can see Lough Swilly, the rugged coastline stretching to Malin Head, and on clear days the distant peaks of the Mourne and Sperrin ranges. A stone megalithic cairn and a classic triangulation pillar mark the top, making it a favourite spot for both hill‑walkers and history enthusiasts.
History
The name Reachtain is thought to derive from an old Irish word meaning “big obscure element”, hinting at the mountain’s ancient significance. The cairn on the summit is a relic of prehistoric ritual activity, a common feature on many Irish peaks where early peoples marked sacred high places. While the exact age of the cairn is unknown, its presence links modern hikers with a landscape that has been revered for millennia. The later addition of a triangulation pillar reflects the mountain’s role in the Ordnance Survey’s 19th‑century mapping of Ireland.
What to See & Do
The Summit Loop
The most popular route begins at the Glenevin Waterfall car park, a small but well‑signposted lay‑by on the R238. From there the trail follows a moderate 8.5 km loop (approximately 3–4 hours) that climbs Raghtin More and its neighbour Raghtin Beag (416 m). The walk traverses the Urris Hills, offering a mixture of open heather, bogland and occasional rocky outcrops. Highlights include:
- Megalithic cairn at the summit – a tangible link to the mountain’s prehistoric past.
- Panoramic sea views over Lough Swilly, Leenan Bay, Dunaff Head, Tullagh Bay and Pollan Bay. The coastline is especially dramatic in the late afternoon light.
- Triangulation pillar – a classic survey marker that provides a perfect photo opportunity.
- Wildlife – the upland heath supports red‑breasted mergansers, meadow pipits and, in summer, a profusion of alpine‑type flowers.
Geology & Wildlife
Raghtin More is composed mainly of metamorphic schist and quartzite, typical of the north‑west Donegal uplands. The thin, acidic soils support a classic heather‑dominated blanket bog that blooms with cotton‑grass, bog‑bean and heather in late summer. Birdwatchers may spot red‑breasted mergansers, golden plovers and meadow pipits, while the higher ground can host mountain hares and occasional red deer sightings.
Seasonal Advice
The mountain is accessible year‑round, but conditions vary:
- Late spring to early autumn offers the longest daylight and the clearest views of Lough Swilly and the distant Mourne and Sperrin ranges.
- Winter can bring snow, ice and strong Atlantic winds. Experienced walkers should use crampons or microspikes and be prepared for reduced visibility.
- Rain is frequent in Donegal; waterproof clothing and sturdy boots are essential at any time of year.
Nearby Amenities
After the walk, the nearby town of Buncrana (about 10 km south) provides a range of cafés, pubs and B&Bs for a well‑earned meal or overnight stay. The Buncrana Harbour also offers parking if you need a larger vehicle space. For those seeking a longer stay, the Inishowen Coast has several self‑catering cottages and guesthouses within a short drive.
Dog‑Friendly Information
Raghtin More lies on open countryside and the trail is dog‑friendly. Keep dogs on a lead in boggy sections to protect the delicate vegetation and to avoid disturbing ground‑nesting birds.
Nearby Attractions
Raghtin More sits within easy reach of several other Inishowen highlights. After your hike you might explore Fort Dunree (a coastal fort with museum displays), the Buncrana Golf Club for a relaxed round, or the iconic Slieve Snaght for a higher‑altitude perspective. The mountain’s location also makes it a convenient day‑trip base for a drive to Malin Head, Ireland’s northernmost point. For a broader mountain experience, consider a visit to the Blue Stack Mountains further south in Donegal.
