🏛️ Attraction

Last updated: 28 April 2026

Overview

Slieve Meelmore (Irish: Sliabh Míol Mór, “great mountain of the ants”) is the seventh‑highest summit in the Mourne range, standing at 687 m (2 254 ft) with a prominence of 109 m. It sits east of the village of Hilltown and forms part of the dramatic ridge that includes Slieve Meelbeg to the south and Slieve Bearnagh to the east. The iconic Mourne Wall – a 35‑km dry‑stone wall built between 1904 and 1922 to define the Silent Valley Reservoir catch‑waters – traverses the summit, offering a handy handrail for the steeper sections.

Geography & Classification

  • Grid Reference: J305 80 286 89 (OSi 29)
  • Listing: Marilyn (prominence > 150 m) and part of the Vandeleur‑Lynam and Arderin mountain lists.
  • Stone Spur: The western ridge bears the name Spellack (from Irish speilic, “splintery rock”), a distinctive rocky spur that adds interest to the ridge walk.
  • Bedrock: Granitic granophyre typical of the Mourne Mountains, giving the summit its stark, exposed tors.

History & Heritage

The name Meelmore derives from the Irish Méal Mór, meaning “great bald hill”, a reference to the exposed granite tors that crown the summit. The Mourne Wall, completed in the early 20th century, was erected to protect the water supply for Belfast. Slieve Meelmore was mistakenly listed as the seventh “Seven” in the annual Mourne Sevens challenge when an old map showed a spot height of 704 m; the error was corrected in 2004 after walkers measured the true height at 687 m.

From the trig point and stone cairn at the top you can see the heart of the Mournes, the tors of Slieve Bearnagh, the glint of Strangford Lough and, on an exceptionally clear day, the rolling hills of the Sperrins. The wall itself provides a dramatic foreground for photographs.

All routes make use of the Mourne Wall for navigation; the wall is especially helpful on the higher sections of Meelmore where the terrain becomes open and exposed.

Points of Interest Along the Way

  • Hare’s Gap – a shallow col bisected by the Mourne Wall, offering a natural rest point and a coffee kiosk.
  • Stone Shelter – a small stone‑built shelter sits at the summit, a perfect spot for a quick break.
  • Pollaphuca Glen – a deep rocky glen on the descent, adding geological interest.
  • Fofanny Dam & Evergreen Wood – encountered on the return via the Ulster Way, providing a contrast of water and woodland.
  • Spellack Spur – the western rocky spur mentioned in the grid reference notes, worth a brief detour for rock‑scramblers.

Flora & Fauna

The lower slopes are cloaked in heather and gorse in late summer, turning a vivid purple. Spring brings a carpet of wildflowers such as bell‑flower and foxglove. Birdwatchers may spot peregrine falcons, ravens and meadow pipits, while the occasional red squirrel can be glimpsed in the mixed‑wood sections near Hare’s Gap.

Practical Information

Getting There

  • Car – The most common start points are the Ott Car Park (near Newcastle, about 5 km from the summit) and the Trassey Car Park on Trassey Road (grid reference J312 314). Both are free, though the Meelmore Lodge car park charges a modest fee for secure parking, coffee, toilets and showers.
  • Public Transport – Translink services run from Belfast to Newcastle (approximately 1 h 30 min). From Newcastle, local buses or a short taxi ride can bring you to Hilltown or directly to the Trassey turn‑off. Check the latest timetables as services are limited.
  • Nearest Towns – Newcastle (≈5 km) and Hilltown (≈2 km) provide shops, cafés and accommodation.

AccessibilityThe terrain is rugged with steep sections; no wheelchair‑accessible routes. A map (OSi 29) or GPS is advisable.

The route is well‑marked by the Mourne Wall, but the only formal signage is the Trassey Track marker at the start. Walkers should carry a map (OSi 29) or a GPS device, especially for the descent from the summit where the wall splits.

Safety

The mountain is classified as “very strenuous” by several walking guides. The ascent involves sustained steep climbs and uneven, sometimes boggy, ground. Stone steps on the Bearnagh side can be slippery when wet. Weather in the Mournes changes rapidly; bring layers, waterproofs and plenty of water.

Seasonal Highlights

  • Late Summer – Heather carpets the northern slopes, creating a purple sea of flowers.
  • Autumn – The granite tors take on a golden hue, and the views over the loughs are especially crisp.
  • Winter – Snow can linger on the higher ground, offering a stark, dramatic landscape for experienced hikers.

Summary of the Experience

A walk up Slieve Meelmore rewards you with a blend of physical challenge, geological interest and sweeping vistas. Whether you tackle the mountain as part of the Bearnagh‑Meelmore circuit or focus on a single summit ascent, the combination of the historic Mourne Wall, the stone shelter and the ever‑changing skyline makes each visit feel fresh.
