Overview
Knocknarea is the flat-topped hill that dominates the views west of Sligo town, its summit crowned by a huge stone cairn, traditionally the grave of the warrior queen Medb, that stands out on the skyline for miles. It rises 327 metres (1,073 ft) above the Coolera Peninsula, a limestone block with steep cliffs on its Atlantic side. The Irish name is Cnoc na Riabh, and its meaning is disputed – you’ll see it rendered as ‘hill of the moon’ and ‘hill of the kings’ both, so take any single translation with a pinch of salt. If you only do one thing here, walk the marked trail towards the cairn: the summit view is the reason to come.
From the summit plateau, the panorama stretches in every direction. You will see the unmistakable flat-topped silhouette of Benbulben to the north and, further off, the rugged spine of the Ox Mountains. To the east lies Lough Gill and the town of Sligo, while the western gaze sweeps across the Atlantic Ocean and the long stretch of Strandhill Beach. On exceptionally clear days, the distant peak of Croagh Patrick in County Mayo can appear on the horizon. The cairn draws people interested in Ireland’s ancient ritual landscapes.
The Climb & Trails
The walk to the summit is strenuous, with steep sections, and the upper slopes are exposed. Bring a windproof layer whatever the forecast: there is no shelter once you are up.
Sport Ireland lists the Queen Maeve Trail as a strenuous 6.5 km loop from Knocknarea car park. Use its current map and follow the marked route, which is waymarked with red arrows on a black background. It includes boardwalk and a wooden bog bridge, and the steps and boards can be slippery in wet weather. Leave dogs at home, as the trail does not allow them.
Access depends on landowner permission for the marked trail. Keep to the route through farmland, respect temporary closures and turn back if conditions worsen. Sligo Walks lists one day of trail maintenance closure each December, so check the date before travelling. The marked trail leads to the summit plateau, where the landscape opens up into a windswept expanse of grass and heather.
Queen Maeve’s Cairn & Archaeology
At the very centre of the plateau sits Queen Maeve’s Cairn, a Neolithic passage tomb dating to around 3000 BCE, roughly a century before the famous tombs of Newgrange. It is a genuinely huge piece of prehistoric construction. The mound measures approximately 60 metres in diameter, rises about 10 metres high, and is built of an estimated 30,000 tonnes of limestone. It has never been opened.
Archaeologists note a quarry about 300 metres to the north, which supplied the limestone for the construction. Evidence suggests the cairn was once clad in quartz, which would have made it glitter at sunrise and sunset. The monument is protected as National Monument No. 153. Look at the cairn from the path, do not climb on the stone structure, and leave the stones in place.
The cairn is part of a wider ritual landscape that includes smaller satellite tombs, ancient hut sites, and a stone embankment that once encircled the summit plateau. Just a short distance down the hill lies the Carrowmore Megalithic Cemetery, a major group of passage tombs that can be combined with a visit to Knocknarea.
Legends & Literary Connections
The hill’s name and reputation are bound up with Medb (often anglicised as Maeve), the warrior queen of Connacht from Irish mythology. Legend holds that she lies upright within the cairn, spear in hand, eternally watching over her province. The story of Medb and her husband Ailill, and their quest for the Brown Bull of Cooley, forms the epic Táin Bó Cúailnge, one of the great works of early Irish literature.
Knocknarea’s bare, windswept summit turns up again and again in the work of W.B. Yeats, who returned to the mountain and its melancholic mood repeatedly. Yeats is buried nearby in Drumcliffe, and his literary legacy adds a layer of cultural resonance to the walk.
Practical Information for Visitors
- What to bring: The summit is exposed and weather conditions can change rapidly. Bring waterproof layers, sturdy footwear with good grip, and plenty of water.
- Route and access: Follow the Sport Ireland trail map from Knocknarea car park and stay on the marked route through farmland.
- Dogs: Dogs are not allowed on the trail. Leave them at home.
- Accessibility: The trail is strenuous, with steep sections, uneven terrain and a wooden bog bridge that can be slippery when wet. It is not suitable for wheelchairs or pushchairs.
- Nearby stops: After descending, visit Culleenamore Strand for a coastal walk.
Plan your visit for early morning or late afternoon to catch the best light on the cairn. Winter visits need extra caution because of shorter days and possible ice on the wooden boardwalks.
