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 and the most northerly summit in the North East Midlands area. The hill is classified as a Hu (Hundred) and offers a striking panorama that can stretch across nine Irish counties on a clear day.
History & Heritage
At the summit lies an impressive cairn, a recognised national monument. 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 was the focus of a recent heritage walk organised by the Clogher Historical Society and the Mullyash Community Group, during which participants listened to a “Heritage at the Heart” podcast recorded on‑site.
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.
What to See & Do
- Summit cairn – Climb the final few metres to the ancient cairn and take in the sweeping vistas. On a good day you can spot the outlines of nine counties, a rare reward for a hill of modest height.
- Monaghan Way – Mullyash forms a natural waypoint on the long‑distance Monaghan Way. Stage 2, Part 1 is an 8 km, roughly two‑hour walk from Clontibret to the mountain, described as easy‑moderate. The route climbs about 175 m, reaching a peak of 311 m before the final ascent to the summit. Stage 2, Part 2 continues from Mullyash to Castleblayney over 14 km, taking around three hours and adding another 138 m of ascent.
- Scenic photography – The open summit provides unobstructed horizons, ideal for sunrise or sunset shots. The cairn itself makes a striking foreground element.
- Local heritage walk – Join a guided heritage walk (often organised by the Mullyash Community Group) to learn about the cairn’s archaeological significance and hear stories from the area’s past.
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.
