Overview
Carnmoney Mountain (often referred to as Carnmoney Hill) dominates the skyline north of Belfast, reaching 232 m (761 ft) and granting unrivalled views of Belfast Lough, the Mourne Mountains and even the Scottish coast on a clear day. The 52.46‑acre (21.23 ha) nature reserve is owned and managed jointly by the Woodland Trust Northern Ireland and Antrim & Newtownabbey Borough Council. Its mix of ancient woodland, semi‑natural grassland, wetland patches and historic earthworks makes it a micro‑cosm of County Antrim’s natural and cultural heritage.
History & Folklore
The hill’s name, Carn Monaidh (cairn of the hill), hints at its long‑standing significance. Dunanney Ráth, a substantial earthen fort on the southern slope, is thought to date to around 500 BC and was once a gathering place for local chieftains. The site also hosts a network of souterrains and the remnants of Victorian limekilns, testifying to centuries of agricultural and industrial activity.
Two colourful legends are tied to the hill. In 1818 Mary Butters, dubbed the “Carnmoney Witch”, was tried for murder after a farmer’s livestock died under mysterious circumstances. Earlier, in 1910 pioneering aviator Lilian Bland built and flew the world’s first woman‑designed biplane, the Mayfly, from a flat on the hilltop – a daring feat that still inspires local pride.
Wildlife & Habitats
The Woodland Trust’s restoration programme has planted 60,000 native trees, creating a thriving mosaic of habitats. Visitors can spot foxes, Irish hares, badgers and a rich bird community that includes buzzards, sparrowhawks, chaffinches and blue‑tits. In spring the wood carpet is a sea of bluebells, primroses and early‑purple orchids; summer brings cornflowers, red campion and buttercups. Dragonflies and a variety of butterflies flit over the pond and scrapes that were added in 2003 to boost biodiversity.
Walks & Views
Three way‑marked routes cater to different fitness levels and time constraints. The routes are colour‑coded on site and downloadable as PDFs.
| Route | Approx. Duration | Difficulty | Highlights |
|---|---|---|---|
| Red (Gentle) | 15 minutes | Easy / Gentle | Pond, island, wildlife hide‑outs; suitable for pushchairs and wheelchairs |
| Yellow (Cross‑Country) | 45 minutes | Moderate / Gentle | Ancient woodland, viewpoint over Belfast Lough; some steep sections |
| Blue (Hilltop) | 2 hours | Strenuous / Moderate | Full summit climb, panoramic vistas of Belfast, Mournes, Slemish and the Antrim coast |
All routes begin at the main lay‑by on Knockenagh Avenue. The Red route follows a level boardwalk around the pond, while the Yellow route weaves through mature oak and birch stands to a modest viewpoint. The Blue route ascends the volcanic cap of the hill, rewarding walkers with a 360° panorama that includes the city lights of Belfast at night.
Events & Activities
Carnmoney Mountain forms part of the Belfast Hills Partnership’s network of community‑led walks. Throughout the summer months the partnership organises guided “Belfast Hills Walks” that often include a stop on Carnmoney for a quick summit break and wildlife spotting. The site is also popular with local bird‑watching groups, especially during spring migration when buzzards and sparrowhawks are most active.
Dog Friendly
Dogs are welcome on all marked routes but must be kept on a short lead, particularly on the steeper summit sections where wildlife may be disturbed. The Red and Yellow routes are suitable for well‑behaved dogs on a leash, while the Blue route’s rougher terrain is best tackled by experienced owners.
Practical Information
Getting there – From Belfast take the M2 then M5, exit at the Carrickfergus roundabout, follow signs to Glengormley and continue on O’Neill Road. Turn right into Knockenagh Avenue; the entrance and lay‑by are on the left. The nearest train station is Whiteabbey (≈ 2.7 mi). Bus services 64A (Belfast City → O’Neill Road) and 2D/E/F (Shore Road → Dough Road) also stop nearby; see https://www.translink.co.uk/ for timetables.
Parking & Facilities – Free parking is available in the lay‑by at the entrance (space for 4‑6 cars). Toilets with disabled access are located in the community centre at the base of the hill and are open when the centre operates. A welcome board at the entrance details the three walking routes and provides QR codes for downloadable maps.
Accessibility – An 800 m paved circuit at the foot of the hill is suitable for pushchairs and wheelchairs, complete with tactile way‑markers. The main summit paths are steep and unpaved, so they are best tackled by those with sturdy footwear and reasonable fitness.
Seasonality – The reserve is open year‑round; there are no entry fees, though parking may be subject to local charges during special events. The Woodland Trust recommends checking the site’s Access Code (downloadable https://belfasthills.org/wp-content/uploads/2023/09/access-code.jpg) for responsible countryside etiquette.
