Overview
Mullyash Mountain sits in the North Midlands range of County Monaghan, standing 317 m (1 040 ft) above sea level. It is the second‑highest point in the county, the most northerly summit in the North East Midlands area and is classified as a HuMP (Hundred Metre Prominence). On a clear day the horizon stretches across nine Irish counties.
History & Heritage
At the summit lies an impressive kerbed cairn, recognised as a national monument (SM 138). Archaeologists date the cairn to the Neolithic period, estimating it to be 4 000–5 000 years old and likely to contain a passage‑tomb. The cairn measures roughly 16 m wide and 1.85 m high, with a stone border that gives it the character of a bowl‑barrow. About 200 m west of the cairn stands a broken standing stone that once rose to 3.6 m.
The cairn sits on the border of the townlands of Mullyash and Tavanaskea in the parish of Muckno, marking a historic landmark that has guided travellers for millennia. The site is a waypoint on the long‑distance Monaghan Way and features in the heritage‑walks organised by the Clogher Historical Society and the Mullyash Community Group.
Folklore & Legends
- Crom Dubh’s Sunday – Traditionally, locals climbed the mountain on the last Sunday in July to celebrate a remnant of the ancient Celtic festival Lughnasadh. The day involved dancing at the cairn and a walk to a nearby standing stone.
- Marriage‑seeking stone – Local lore says the standing stone was once used by young people to find a partner; couples would leave a token at its base.
- Fionn mac Cumhaill – A legend claims the giant hero threw a stone from Slieve Gullion to Mullyash, landing where the standing stone now stands – a distance of about 16 km.
Recent Events
- 2022 Charity Walk – Mary Conway climbed Mullyash on 2 April 2022 in memory of her husband, mirroring Charlie Bird’s ascent of Croagh Patrick for the Irish Motor Neurone Disease Association.
- Annual Heritage Walks – Each spring the Clogher Historical Society and Mullyash Community Group host guided walks that include a talk, a listening session of the “Heritage at the Heart” podcast recorded on‑site, and a visit to the cairn.

Practical Information
Mullyash Mountain is freely accessible; there is no admission fee and no formal opening hours. The most common approach is from the village of Clontibret, where the Monaghan Way trailhead is marked. The walk to the summit is well‑trodden but not heavily way‑marked, so carrying a map (Discovery Map 28 is recommended) or a GPS device is advisable.

The summit cairn is a protected monument; visitors are asked to treat it with respect and avoid moving stones. The terrain is suitable for families and casual walkers, though some sections can be boggy after rain. Dogs are welcome on the trail but should be kept on a lead near the cairn and standing stone to protect the fragile archaeology.
Navigation & Maps
- GPS coordinates: 54.1762 ° N, 6.6706 ° W (Latitude 54.1762, Longitude ‑6.6706).
- OS Grid Reference: H868262 (also given as H868 47 261 28 on some maps).
- Map resources: Detailed routes are available on the MountainViews page for Mullyash Mountain, on the Mud & Routes guide, and via the ActiveME Monaghan Way guide.
- Elevation note: Most hill‑bagging databases (MountainViews, Harold Street) list the height as 317 m, while Monaghan County Council’s heritage page cites 315 m. The difference is within typical survey tolerances; walkers can expect a summit around 315‑317 m.
Access & Parking
The main trailhead is located on the R185 road just outside Clontibret village. A small public car park adjacent to the community centre provides free parking for walkers. From the car park, follow the sign‑posted forest track that leads onto the Monaghan Way. The route is well‑maintained but can become muddy in wet weather, so sturdy walking shoes are recommended.
Geology & Landscape
According to MountainViews, Mullyash is composed of massive sandstone and micro‑conglomerate belonging to the Oghill Formation. The hill rises from the characteristic drumlin landscape of north‑eastern Monaghan, offering a mix of open heath, low‑lying bog and scattered conifer plantations. The summit provides an excellent viewpoint for spotting the surrounding counties: Monaghan, Cavan, Donegal, Louth, Meath, Leitrim, Longford, Westmeath and Sligo on exceptionally clear days.
Flora & Fauna
The heath‑dominated summit supports typical low‑land heath species such as heather, bilberry and gorse. The surrounding boggy patches are home to sphagnum mosses and wet‑land wildflowers. Conifer plantations on the lower slopes provide shelter for birds like the goldcrest and chiffchaff, while the open heath can attract meadow pipits and occasional hares. Visitors are encouraged to stay on the established path to protect these sensitive habitats.
Seasonal Tips
- Best viewing: Late spring to early summer often brings clear skies and the longest daylight, ideal for panoramic photographs.
- Weather: The summit can be windy; a wind‑proof jacket is advisable year‑round.
- Boggy ground: After heavy rain the heath and bog sections become slippery – sturdy boots and gaiters are recommended.
- Sunrise/Sunset: The unobstructed horizon makes both sunrise and sunset rewarding; check the sun’s position in advance to pick the optimal side of the cairn.
Guided Heritage Walks (2024‑2025)
The Clogher Historical Society, in partnership with the Mullyash Community Group, runs two heritage walks each year:
