Overview
Mullaghmesha (Irish: Mullach Méise, ‘summit of the altar’) stands 494 metres above the patchwork of West Cork fields, a flat-topped summit with views in every direction. It sits between Bantry and Drimoleague and forms a key section of the Sheep’s Head Way (Eastern routes) and the historic St Finbarr’s Pilgrim Path.
From the summit cairn you can look north to the Kerry mountains, south to Roaring Water Bay, west across Bantry Bay and east towards Dunmanway. The walk is graded strenuous for its steep climbs, boggy ground and exposed ridges, but the payoff is a sense of openness you rarely get in the lowlands.
History and heritage
The ground around Mullaghmesha is thick with local history. At the foot of the hill stands Castle Donovan, a 16th-century stronghold built by the O’Donovan clan that still commands the valley.
The summit was a traditional meeting place for generations. Standing stones known as the Dhá Liag once marked the gatherings, and medieval fairs (an t-Annoch Mór) were held nearby. Local tradition holds that St Finbarr preached here in the 6th century, and in the 1860s the Fenian leader Jeremiah O’Donovan Rossa came to the site to call for peace during a spell of intense faction-fighting.
Route options
Mullaghmesha is usually walked as a loop. The official Mullaghmesha Loop is 12km with 479m of ascent and takes around four hours. There are two common starts, each with a different profile.
Starting at Mealagh Community Hall
This one puts the hard work in first. From the Mealagh Community Hall, follow the road south for about 1.2km. The trail then leaves the road, zig-zagging uphill past old peat cuttings before crossing boggy ground to the summit cairn. From the top, a gentle ridge walk runs east to meet the Bearna-na-fola road, which winds downhill through the valley back to the hall.
Starting at Castledonovan car park
This route begins at the castle car park, following a quiet country road before turning off to climb the east side of Mullaghmesha. It is a steadier climb and passes Coomanore Lough, a quiet lake that mirrors the sky and makes a good spot for wildlife. The loop returns to the car park on an old bog road.
Highlights along the trail
- Glanacloghy Rocks – on the ridge, these twin rocks give the area its name (Glanacloghy, ‘glen of the rocks’). One balances on a narrow base, topped with a tuft of vegetation, and makes a natural resting spot.
- Altar Wedge Tomb – a short detour from the ridge leads to this well-preserved Neolithic tomb. (Altar Wedge Tomb)
- George the Sky – a ruined 19th-century homestead of the hill farmer George Mahony. A way-marker points to it, though the path can be seriously wet and boggy.
- Flora and fauna – heather, sphagnum moss and bleached grasses cover the hill, skylarks are regular at the summit, and on clear days visibility reaches Fastnet Rock.
Practical information
Difficulty and conditions This is a strenuous hill walk over steep inclines, slippery bog and exposed ridges. Good map-reading and hill-walking experience are essential. The path is way-marked and appears on OS Discovery series map 85.
Weather warning Mullaghmesha should not be attempted in cloudy or misty conditions. Visibility can drop fast on the exposed ridges, making navigation hazardous. Check the forecast and be ready to turn back if the weather closes in.
Facilities and parking Both the Mealagh Community Hall and Castledonovan car parks are free. There are no facilities on the hill, with the nearest amenities in Bantry and Drimoleague. Bring plenty of water, food and sturdy waterproof footwear.
Getting there Mullaghmesha is at 51.6903 N, 9.2822 W. From Bantry, follow the R585 towards Drimoleague; the Castledonovan car park is signposted. The Cork bus service to Drimoleague allows a park-and-ride for those without a car.

The telecoms mast on the summit means mobile reception is generally reliable, but do not lean on it for navigation. Download your route beforehand, wear layers for the wind, and time your arrival for the afternoon light turning the heather purple against the grey Atlantic.
