Devilsmother

Overview

Devilsmother (Irish: Magairlí an Deamhain or Binn Gharbh) is a 645‑metre summit that crowns the western edge of the Partry Mountains in Connemara. Perched at the head of Killary Harbour – Ireland’s only true fjord – the peak commands sweeping views of the harbour, Lough Nafooey and the rugged coastline beyond. The mountain straddles the border between County Galway to the south and County Mayo to the north, making it a natural landmark for walkers traversing the Western Way long‑distance path.

History & Etymology

The dual Irish names translate intriguingly: Magairlí an Deamhain means “the demon’s testicles”, while Binn Gharbh simply describes a “rough peak”. Early maps recorded the anglicised forms Mogarlyandoon and Ben Garrif. Some scholars suggest that Magairlí an Deamhain originally referred only to a knobbly ridge on the mountain’s northern side, with Binn Gharbh applying to the whole summit. The English name Devilsmother may be a euphemistic reinterpretation of the original Irish, or perhaps a corruption of an older local name.

Geology & Landscape

Devilsmother sits on a foundation of sandstone and conglomerate, with ignimbrite intrusions belonging to the Mweelrea Formation. The summit’s rugged profile is the result of extensive glacial erosion, which also carved the deep‑walled valleys and waterfalls that characterise the Partry range.

Folklore & Naming

Beyond its literal translations, the mountain’s English name may echo the myth of the Caoránach – a female demon said to have been banished by St Patrick to Lough Derg and sometimes referred to as the “Devil’s Mother”. While there is no direct evidence linking the myth to this specific peak, the evocative name has helped cement its reputation in local folklore.

What to See & Do

The Glennagleragh & Devilsmother Loop

One of the most popular ways to experience the mountain is the 12.2 km loop that starts at Loch Na Fooey. The route climbs the neighbouring peak of Glennagleragh before tackling Devilsmother’s summit ridge. According to hikers on Hiiker, the loop offers a difficult grade, with an elevation gain of 912 m and an estimated completion time of just under four hours.

Feature	Details
Trail length	12.2 km
Estimated time	~3 hrs 57 min
Elevation gain	912 m
Difficulty	Difficult (4.5★ rating)
Route type	Loop
Starting point	Loch Na Fooey (coordinates 53.58082, -9.58848)

The ascent rewards walkers with dramatic ridgelines, open‑plateau sections, and, at the summit, a 360‑degree panorama that includes Killary Harbour, Lough Mask, the Maam Valley and distant peaks such as Maumtrasna and the Twelve Bens. The descent follows a well‑marked path that drops back into the tranquil waterside of Loch Na Fooey, a perfect spot for a post‑hike rest.

Alternative Routes

For those approaching from the Mayo side, an 8.5 km Devilsmother Mountain Ridge Loop starts and finishes in the Erriff electoral division. Listed on Hiiker, the route climbs directly from the road‑side trailhead, gaining 674 m in elevation and taking roughly 2 hrs 50 min. It is also graded Difficult and follows a slightly different ridge line, offering comparable summit views but a shorter overall distance. Both loops can be combined with a walk to the nearby Knocklaur summit for a longer ridge‑walk experience.

Winter Climbing

During the winter months the north‑facing corrie and upper ridge can hold firm snow and ice. Local climbers have recorded short ice‑gully routes on the north side (see the Irish Climbing Wiki entry for Devilsmother/Maumtrasna). These routes are typically graded III–IV and require ice axes and crampons. Conditions are highly variable; only experienced winter mountaineers should attempt them, and a thorough check of recent snow and ice reports on the Mountain‑Forecast site is essential.

Flora, Fauna & Birdwatching

The mountain’s heath‑covered slopes support typical Connemara flora such as heather, gorse and bell heather. In summer, the higher ground blooms with alpine saxifrages and mosses. The open terrain attracts a range of upland birds: skylarks and meadow pipits are common, while peregrine falcons and, more rarely, merlins have been recorded hunting over the sheer northern cliffs. Early mornings are the best time to spot these raptors, especially when the wind is calm.

Parking & Access Details

The most convenient access point remains the village of Leenane. From the N59, a small lay‑by (approximately one car) sits at grid reference L935 655 near the bridge; a gate here leads onto a short track that soon becomes the steep ascent to the ridge. An alternative lay‑by at the Otr Pl (L912 650) allows a more direct, though very steep, climb from the southeast. Both lay‑bys are free, but space is limited, so arriving early in the season is advisable.

A second road approach starts from the minor road at Fooey Rd (grid L936 611). From this point the ridge can be reached after a 400 m walk on a low‑grade track before the steep climb begins at grid L929 648. A third, longer option begins at Carraig Bar on the N59 north of Leenane; a gate on the right‑hand side of the road provides access to the open mountain and a 2.5 km climb to the North Top before the ridge continues to the main summit.

Practical Information

Getting There

Leenane lies at the junction of the R336 and the N59. While public transport is limited, Bus Éireann’s Route 419 (Galway – Oughterard – Clifden) stops in Leenane, providing a link to the trailhead. From Leenane, follow signs for Loch Na Fooey and the lay‑by described above.

Accommodation & Services

Leenane and the nearby village of Clonbur provide a range of lodging options, from hotels and B&Bs to the Sleepzone hostel in Leenane and the Ben Lettery hostel further south. Both villages have grocery stores, cafés and pubs where hikers can refuel after a day on the mountain.

The summit is marked on the Ordnance Survey Discovery Series Sheet 38 (scale 1:50 000). Digital GPS tracks for both the Glennagleragh & Devilsmother Loop and the shorter Devilsmother Mountain Ridge Loop are available on the Hiiker website. The MountainViews entry lists the grid reference L915 68 624 47 for precise navigation.

Safety Notes

Hillwalking in the Partry Mountains is classified as a risk sport. The loops involve steep ascents, exposed ridges and potentially boggy sections, especially after rain. Hikers should be comfortable with difficult terrain, carry a map, compass and a fully charged phone, and consider the weather forecast before setting out. The summit cairn is easy to locate, but the northern ridge can be narrow and windy.

Weather & Seasonal Advice

Western Irish weather changes rapidly; checking the latest forecast on the Mountain‑Forecast page for Devilsmother is essential. Late spring to early autumn (May – October) generally offers the most reliable conditions, with longer daylight hours and clearer skies. The summer months (June‑August) are especially popular for the best visibility of the surrounding fjord and distant peaks. Winter can bring snow and strong winds, making routes considerably more challenging and suitable only for experienced winter walkers or climbers.
