Slievenamuck – Tipperary’s Red-Sandstone Ridge

Overview

Slievenamuck (Irish: Sliabh Muic, “mountain of the pig”) is a prominent peak in the heart of County Tipperary, forming the western edge of the Glen of Aherlow. Reaching 369 m (1,211 ft) with a topographic prominence of 234 m, it sits atop a 300-million-year-old Old Red Sandstone ridge that runs east-west between the Galtee Mountains and the Aherlow valley. While it doesn’t rival the Galtees in height, Slievenamuck offers a more accessible, family-friendly walking experience with fewer crowds, making it a favourite for locals and visitors seeking a blend of geology, archaeology, and open-air art.

Geology & Landscape

The ridge is built from the Slievenamuck Conglomerate Formation, a hard, purple-reddish rock that resists erosion and gives the hill its distinctive colour. Historically, the area was known as Sliabh gCrot (“the hump mountains”), a direct reference to the rounded, undulating profile of the ridge. The exposed sandstone outcrops along the summit provide a natural outdoor classroom for geology enthusiasts. The stone’s rich hue is particularly vivid after rain, and the long, grassy ridgeline offers uninterrupted panoramas across the valley. From the summit, walkers can look east toward the Galtees, south toward the River Aherlow winding through the valley floor, and on clear days, catch sight of the distant Knockmealdown range.

History & Folklore

Slievenamuck’s name is thought to derive from an old Irish word for “pig”, hinting at the hill’s wild pastoral past and the feral swine that once roamed the Glen of Aherlow. The wider Galtee range features heavily in early Irish literature and local legend. One enduring tale involves Saint Patrick, who is said to have banished a serpentine creature that was terrorising livestock and confined it beneath the nearby corrie lakes. According to folklore, the serpent emerges every Easter Monday to ask, “Is it the Monday morning yet, Patrick?” When told it is not, it returns to its underwater slumber for another year. This legend is traditionally tied to Lough Dihneen, but local lore often extends it across the valley’s glacial lakes. The belief in the serpent was once so strong that a 19th-century local landlord attempted to drain Lough Dihneen to kill it, only to abandon the project when the local community protested.

Walking Routes

Slievenamuck is criss-crossed by several well-signposted loop walks. All routes are classified as moderate and can be tailored to your fitness level. The trails connect seamlessly with sections of the Ballyhoura Way, a long-distance walking route.

The Lisvarriane Dolmen Loop begins at the Lisvarrinane Village Trail Head, a small car park off the R639 near the village of Lisvarrinane. The Millennium Stone Loop and the Dolmen Loop start from the Christ the King Trail Head, situated beside the iconic Christ the King statue that overlooks the Glen of Aherlow.

Key Stops Along the Trails

• Shrough Dolmen – A massive Neolithic portal tomb dating to around 5,000 BC, perched on a low spur of the ridge. Its enormous capstone makes a striking silhouette against the sky and is easily visible from the main trail.
• Millennium Stone – A 13.5-tonne boulder sculpted by a local artist to depict scenes from the life of Christ. It sits on a small hill adjacent to the ridge and serves as a popular resting point and photo spot.
• Christ the King Statue – Erected in 1950, this bronze figure watches over the valley and marks the western trailhead for several walks. The adjacent Glen of Aherlow Visitor Centre offers information panels on local flora, fauna, and folklore, plus a small café and picnic tables.
• Summit Cairn – A traditional stone marker at the peak, offering 360-degree views. The ridge can be exposed in high winds, so visitors should stay on the marked path, especially near the cairn.

Practical Information

Slievenamuck is freely accessible to the public with no admission fee. The main trailheads have free parking and are reachable via the R639, which links the towns of Bansha and Galbally.

• Difficulty & Terrain: The walks are moderate. The terrain is mostly well-trodden, with occasional short scrambles over stone steps near the dolmen. Strollers can manage the lower sections of the Lisvarriane Loop, but the steeper climbs on the Millennium Stone Loop are better suited to older children and adults.
• Dogs: The routes are dog-friendly, but dogs should be kept on a lead in more exposed summit areas and around livestock grazing on the lower slopes.
• Navigation: Mobile phone coverage is generally good along the ridge, but a paper map or GPS device is advisable, especially in poor weather. Downloadable GPX files and detailed route maps are available via the ActiveME guides:
  • Lisvarriane Dolmen Loop Walk
  • Millennium Stone Loop Walk
  • Dolmen Loop Walk, Lisvarrinane
• Getting There: From Limerick, take the N24 east to Bansha and follow signs for the R639 towards Lisvarrinane. From Dublin, the drive via the M7 and N24 takes roughly two hours. Public transport is limited; the nearest bus stop is in Bansha, from where a short taxi ride will bring you to the trailhead.
• Safety: The ridge can be exposed in high winds and slippery after rain. Keep an eye on children near the summit cairn and ridge edges. The Glen of Aherlow Visitor Centre is open year-round and free of charge, making it a useful starting point for route planning.

Nearby Attractions

If you have time after exploring Slievenamuck, the surrounding area offers several complementary stops:

• Arra Hills – A series of low, rounded hills east of the Glen of Aherlow, offering gentle walks and sweeping views over the River Shannon.
• Devil’s Bit – A dramatic limestone peak with its famous “bit” rock formation and an extensive trail network, located a short drive south.

Slievenamuck rewards visitors with a quiet, accessible hillwalk that layers ancient geology, Neolithic archaeology, and living folklore into a single afternoon. Start early in the morning to catch the light on the red sandstone, and allow plenty of time to stop at the dolmen and take in the valley views.
