Keeper Hill

Overview

Keeper Hill (Irish: Sliabh Coimeálta, “mountain of guarding”) dominates the Silvermine Mountains in north-eastern County Tipperary. At 694 m (2,277 ft) it is the highest point in the Shannon region and ranks as Ireland’s 58th-highest summit. The hill sits about 15 km east of Limerick City and is most easily reached from the village of Toor or the town of Murroe. Its slopes are a patchwork of conifer plantations, native beech, ash and larch, while the summit plateau is a 300-hectare blanket-bog and Nardus-grassland designated as both a Special Area of Conservation (SAC) and Special Protection Area (SPA).

A stone circle known locally as Firbrega (“false men”) rests on the northeastern shoulder in Bauraglanna townland, hinting at the hill’s ancient ritual significance. Historically, a Lughnasadh gathering was held on the summit each August, linking the landscape directly to Ireland’s Gaelic festival calendar.

Geology & Landscape

The hill is formed from the Keeper Hill Formation – a mix of pale red sandstone, grit and claystone. This underlying geology supports the extensive blanket-bog on the summit, a habitat of European importance that retains moisture and stores significant carbon. The surrounding forest, managed by Coillte, covers roughly 3,300 hectares and includes a diverse mix of beech, larch, spruce, ash and pine. The transition from dense woodland to open bog creates a distinct change in light and sound, making the final approach to the summit feel like stepping out onto the roof of the region.

History & Cultural Background

The name Keeper Hill derives from a mythic tale about Sadb, daughter of Conn of the Hundred Battles, who raised her children on the mountain after being rejected by their father, Ailill Aulom, king of Munster. The alternative name Slievekimalta comes directly from the Irish Sliabh Coimeálta, reinforcing the idea of the hill as a guardian of the surrounding valleys.

Archaeological remnants – the Firbrega stone circle and a stone sweat-house near the forest road – testify to long-standing human activity. In the early 19th century the summit was used as a trig point in the first Ordnance Survey triangulation of Ireland (1829-1832). Surveyors recorded sight-lines reaching as far as Cuilcagh (164 km) and Baurtregaum on the Dingle Peninsula (122 km), proving just how far the visibility extends on a clear day.

What to See & Do

• Summit Views – From the cairn-topped summit you can see the rolling Tipperary countryside, the Limerick City skyline, the River Shannon and, on a clear day, the distant Galtee Mountains, Devil’s Bit and even the Maam Turks.
• Firbrega Stone Circle – Eleven orthostats of varying height, with a large recumbent stone at the centre, sit on the northeastern slope. The arrangement is typical of late Neolithic ritual sites found across Munster.
• Sweat-House – A small stone structure traditionally used for steam-bathing, located along the Ballyhourigan Loop. It offers a quiet moment of reflection away from the main trail.
• The ‘Spout’ Waterfall – A seasonal cascade visible from the forest road on the way to the summit, most dramatic after winter or spring rains.
• Wildlife – The SAC supports raptors such as the hen-harrier (white-silver male, brown female) and other birds of prey; spring brings a chorus of meadow-larks and skylarks.
• Woodland Walks – The Doonane/Ballyhourigan forest offers several side-trails to hidden streams and viewpoints, ideal for breaking up the climb.

Trail Details

The walk begins at the Doonane Forest car park – a large gravel semicircle on a minor road north of Bleanbeg Bog, just across the River Doonane. Follow the red-arrowed lane northward; after about 2 km you reach a crossroads where the purple-arrowed lower-shoulder loop diverges. The summit trek continues on red arrows, climbing steeply through mixed forest before breaking out onto the blanket-bog plateau. Allow extra time if you plan to detour to the stone circle or sweat-house.

Practical Information

Getting There

The trailhead is sign-posted from the R506. From Toor, follow the unclassified road toward Newport for 2 km, then turn right onto the minor road marked with trailhead signs. The car park is free and can accommodate several cars and a few bicycles. There are no toilets or refreshment points on the hill, so pack water and snacks accordingly.

Seasonal Advice

The hill is best tackled in late spring to early autumn when the weather is milder and the blanket-bog is dry enough for safe footing. Summer can bring occasional mist that obscures views; early mornings often offer the clearest panoramas. In winter, the bog becomes waterlogged and the forest roads can be icy, so heavy boots and a waterproof jacket are essential. The historic Lughnasadh gathering took place in August, but today the summit is quieter, making midweek visits ideal for solitude.

Flora & Fauna

The SAC supports a range of upland habitats. Look out for:

• Hen-harrier – distinctive white-silver male in breeding season.
• Red grouse, meadow-lark, skylark – common in the open bog.
• Plant life – Nardus grass, heather, and rare mosses on the bog surface.

Visitors are asked to stay on marked paths to protect these sensitive habitats. The bog ecosystem is fragile and recovers slowly from foot traffic.

Nearby Walks & Extensions

• Arra Hills – a gentle ridge walk 30 km north, offering lake views.
• Devil’s Bit Mountain – a classic Munster climb 45 km west, reachable as a day-trip.
• Doonane – additional forest trails and woodland walks starting from the same car park area.
• Clare Glens – a red-sandstone gorge with waterfalls, 12-minute drive.
• Glenstal Abbey – historic abbey and landscaped woods, 20-minute drive.
• Knockanroe Woods – 4.3 km loop of wildflower-rich forest, 20-minute drive.

Conservation & Responsible Visiting

Keeper Hill is a designated Special Area of Conservation and Special Protection Area. Visitors should:

• Stay on waymarked trails.
• Avoid disturbing nesting raptors, especially April to July.
• Carry out all litter.
• Keep dogs on a lead at all times.
• Refrain from walking on the blanket-bog to prevent erosion.
