Slieve Martin

Overview

Slieve Martin (Irish: Sliabh Mártain) is a 485 m (1,591 ft) hill that crowns the southern edge of the Mourne Mountains in County Down. Nestled within Kilbroney Forest Park, the summit commands sweeping views over the glacial fjord of Carlingford Lough, the Irish Sea and the surrounding Mourne peaks such as Slieve Donard and Binnian. Its gentle prominence (179 m) makes it one of the most accessible Mourne summits, attracting hikers of all abilities, families, and dog‑owners looking for a rewarding day out.

History & Background

The hill has long been a landmark for the villages of Rostrevor and Kilbroney. Local folklore tells of the massive 50‑tonne Cloughmore Stone – a glacial erratic perched on the slopes – being hurled by the giant Finn McCool. Geologists, however, agree the boulder was deposited during the last Ice Age. The area also inspired C. S. Lewis, who spent his childhood exploring the forest; the Narnia Trail, a whimsical walk through the woods, commemorates the author’s imagination.

Legend & Folklore

The Cloughmore Stone, often called the Big Stone, dominates the mid‑slope. Legend says Finn McCool threw the boulder across Carlingford Lough in a fit of rage, landing it where it now sits. A local custom holds that walking around the stone seven times brings good luck – a tradition many visitors still follow at the spot known locally as Kodak Corner.

Trail Options & Routes

The most popular ascent starts from the upper car park (grid reference 185 176) in Kilbroney Forest. From here the path climbs through mixed oak‑conifer woodland before opening onto the open heather‑clad slope that leads to the summit trig pillar. The round‑trip is about 3 km and takes 1.5 hours for most walkers.

Two alternative starting points are worth noting:

• Cloughmore car park – a higher, smaller car park located next to the iconic boulder. A notice board here shows several marked routes, including the Fiddlers Green and Oakwood trails, which give a slightly longer but quieter approach to the summit.
• Lower car park at the Kilbroney Park entrance – useful if you need the café, public toilets or want to combine a visit to the Fairy Glen walk before tackling the hill.

All routes are well‑marked on the forest’s information boards and on the OS map (grid reference J20120 17646). Choose the upper car park for the quickest ascent, or the Cloughmore car park if you want to linger at the Big Stone before heading up.

What to See & Do

• Cloughmore Stone – A short detour from the main path leads to the iconic boulder, offering a dramatic backdrop for photos and a picnic spot with views of Carlingford Lough and Slieve Foy. The viewpoint is also known locally as Kodak Corner.
• Narnia Trail – This family‑friendly loop winds through ancient oakwood, conifer plantations and mixed woodland, with whimsical signage referencing Lewis’s world. It is suitable for all ages, though uneven ground makes prams impractical.
• Summit Trig Pillar & Cairn – After a short, steep climb from the upper car park, a grassy mound leads to the trig pillar and a modest cairn. From here you can see the Cooley Peninsula, the Irish Sea, and the Mourne peaks stretching to the horizon.
• Wildlife & Woodlands – The forest hosts a variety of birds, including jays and woodpeckers, and the mixed habitats support deer, badgers, red squirrels and a rich understory of heather, gorse and bluebells in spring.
• Nearby Attractions – Rostrevor village, known as the “Riviera of the North”, lies at the foot of the hill and offers pubs, cafés and the historic Ross Monument. The Ross Monument is an obelisk erected by the Ross family in the 19th century. A small listed church nearby houses the 900‑AD bell of St Bronach, said to ring mysteriously at night. Kilbroney Park also hosts the Fairy Glen walk.

Historical Sites Nearby

A short walk from the trailhead brings you to the Ross Monument, an 19th‑century obelisk commemorating the Ross family who once owned the Kilbroney estate. Nearby stands the ruins of an early church where the ancient bell of St Bronach, cast around 900 AD, is displayed – locals claim the bell sometimes sounds on its own.

Events & Races

Each spring the hill becomes the centrepiece of a community trail race organised by Newcastle AC. The Slieve Martin Trail Run (usually held on the last Saturday of April) covers 8 km with roughly 500 m of ascent, starting from the Kilbroney Forest car park (grid reference 185 177). Entry fees are £12 for affiliated runners and £14 for unaffiliated runners; participants must be at least 15 years old. The race is part of the Hill and Dale series and entries are managed through the SiEntries platform (entry window 20 Mar – 29 Apr). After the race a presentation is held at the Cloughmór Inn in Rostrevor.

Charity & Community Challenges

Since 2023 the hill has been the focus of a charitable climbing challenge. Local resident Raymond McDonald aims to summit Slieve Martin 365 times in a year to raise funds for Autism NI. The daily climbs have drawn media attention and demonstrate the mountain’s role as a community rallying point.

Mountain Biking

Kilbroney Forest is recognised as one of Ireland’s premier mountain‑biking destinations and is listed as a national trail centre by Trailbadger and BikeRadar. The forest offers a 27 km red‑grade trail and a 19 km black‑grade trail that both pass close to Slieve Martin, providing a mix of single‑track, jumps and technical sections. The locally‑named “Slieve Martin Slaughter” comprises four looped routes (Green, Blue, Yellow, Red) that combine forest tracks, open moorland and the summit approach. All routes are marked on the MountainBikeNI website, and the trailhead at Kilbroney Park provides a café, free parking and basic bike‑service facilities. Downhill races are also hosted here each year.

Getting There & Transport

• By Car – From Belfast or Newry follow the A2 coastal road to Rostrevor (≈46 mi from Belfast, 15 km from Newry). The upper car park in Kilbroney Forest is accessed via a narrow, one‑way forest drive; the lower car park at the park entrance offers a café, public toilets and additional spaces.
• Public Transport – Regular Ulsterbus services run from Belfast and Newry to Rostrevor via the A2. Once in the village, follow the signs for Kilbroney Park; the trailhead is a short walk from the bus stop.
• Cycling – The Rostrevor to Carlingford Greenway provides a traffic‑free, scenic route for cyclists wishing to combine a ride with a hike.

Seasonal & Weather Tips

• Spring – Bluebells carpet the lower woodland, and red squirrels are most active. Early morning light filters through the trees, creating soft contrasts.
• Summer – Long daylight hours make the 1.5‑hour round‑trip ideal for families. The summit offers 360° panoramas; sunrise over Carlingford Lough is especially striking.
• Autumn – Heather and gorse turn gold, providing vivid foregrounds for sunset shots.
• Winter – Snow‑capped peaks and crisp air give a dramatic mood; be prepared for icy paths and reduced daylight.

For photographers, the best light is usually golden hour (just after sunrise or before sunset) when the Lough reflects warm tones. A wide‑angle lens captures the full sweep of the Cooley Mountains, while a telephoto can isolate the Cloughmore Stone against the sky.
