Overview
Mullyash Mountain rises to 317 m (1 040 ft) in the North Midlands range of County Monaghan, standing as the county’s second-highest point and the most northerly summit in the North East Midlands area. Classified as a HuMP (Hundred Metre Prominence), the hill punches well above its weight. On a clear day, the open summit reveals sweeping views across nine Irish counties. The mountain is a recognised waypoint on the National Waymarked Monaghan Way and serves as a quiet, rewarding destination for walkers, hill-baggers, and heritage enthusiasts.
History & Heritage
The summit is dominated by an impressive kerbed cairn (National Monument SM 138), a protected archaeological site that has anchored this landscape for millennia. Archaeologists generally date the structure to the Neolithic period, estimating it was built 4 000–5 000 years ago. Measuring roughly 16 m wide and 1.85 m high, the cairn features a distinct stone border that gives it the appearance of a bowl-barrow. Most experts agree it likely conceals a passage tomb, a common burial style for early farming communities in Ireland.
About 200 m west of the cairn stands a broken standing stone that once reached 3.6 m in height. The monuments sit on the border of the townlands of Mullyash and Tavanaskea in the parish of Muckno, near the county boundary with Armagh. For centuries, these stone markers served as navigational aids and boundary stones, long before modern roads or trails crossed the drumlin landscape.
Folklore & Legends
Local oral traditions have kept the mountain’s ancient atmosphere alive:
- Crom Dubh’s Sunday – Until the mid-20th century, locals traditionally climbed Mullyash on the last Sunday in July. The custom was a surviving remnant of the ancient Celtic harvest festival Lughnasadh, marked by dancing at the cairn and a ritual walk to the nearby standing stone.
- The Marriage-Seeking Stone – Folklore claims young people once visited the standing stone to find a partner. Couples would leave a small token at its base as a pledge, and the stone was said to guide them toward their match.
- Fionn mac Cumhaill’s Throw – A local legend insists the giant hero Fionn mac Cumhaill hurled a stone from Slieve Gullion to this very spot, a distance of roughly 16 km. The standing stone marks where it allegedly landed.
Walking the Monaghan Way
Mullyash Mountain sits directly on the Monaghan Way, a long-distance trail designated as a National Waymarked Trail. The mountain forms the climax of Stage 2, which is typically split into two manageable sections:
- Stage 2, Part 1: An 8 km, easy-to-moderate walk from Clontibret to the summit. The route climbs steadily through open countryside and takes around 2 hours.
- Stage 2, Part 2: A 14 km descent and traverse from the mountain to Castleblayney, finishing near Lough Muckno. This leg takes roughly 3 hours and follows former railway alignments and quiet rural roads.
The trail is well-trodden but not heavily signposted throughout. Carrying a physical map or a reliable GPS app is strongly recommended, especially if you plan to navigate the return route independently.
Practical Information & Access
There is no admission charge and no formal opening hours; the mountain is accessible year-round. The primary trailhead is located on the R185 road just outside Clontibret village. A small public car park adjacent to the community centre offers free parking for walkers. From the car park, follow the marked forest track that feeds onto the Monaghan Way.

The terrain is generally straightforward, though heath and boggy patches can become slippery after rain. Sturdy walking shoes or boots are advisable. The summit cairn and standing stone are protected monuments; please stay on established paths, do not move stones, and keep dogs on a lead near the archaeology to preserve the site.
Seasonal Tips & Nearby Attractions
- Best viewing: Late spring through early summer usually offers the clearest skies and longest daylight, ideal for panoramic photography.
- Weather preparedness: Exposed summits can be windy regardless of the season. A windproof jacket and layers are sensible year-round.
- Boggy ground: After prolonged rain, the heathland and peat sections turn soft. Gaiters or waterproof boots will keep you comfortable.
- Heritage walks: The Clogher Historical Society and Mullyash Community Group run seasonal guided walks, typically in spring. These include a talk at the community centre, a listening session of the “Heritage at the Heart” podcast recorded on-site, and a guided ascent. Dates are announced via the Monaghan County Council heritage website and local community pages; booking in advance is recommended as group sizes are capped to protect the monuments.
After your summit, consider pairing the walk with a visit to Carrickmacross, a nearby market town known for its historic lace gallery and 18th-century church, or extend your route south along the Monaghan Way to explore the lakeside town of Castleblayney. Check the Monaghan County Council heritage office (047 73722) for current walk dates and route updates before heading out.
