Knocknarea

Knocknarea rises to 327 metres above the Sligo coast and is visible from most of the county. On its flat summit sits Miosgan Meadhbha, a cairn about ten metres high and fifty-five across, built around 3000 BC and never excavated - it almost certainly covers a passage tomb, and it is one of the largest unopened monuments of its kind in Europe. Tradition names it as the grave of Queen Maeve of Connacht, buried upright facing her enemies in Ulster, though the cairn predates any historical figure by millennia. There is a long-standing custom of carrying a stone up and adding it to the pile, and archaeologists now ask people not to - the cairn has been visibly damaged by walkers climbing on it, and the Queen Maeve Trail was built partly to manage the pressure. The summit view covers Sligo Bay, Benbulbin, the Ox Mountains and Donegal.

What you actually see

• The cairn - ten metres high, around 3000 BC, never excavated.
• The summit plateau - flat ground with a view over most of Sligo.
• The Queen Maeve Trail - the built path up from the Strandhill side.
• The tradition - the stone-carrying custom, now discouraged.

When to go

April to October. The built trail makes it manageable year-round, but the summit is exposed and windy. Early or late gives the best light over the bay.

Honest expectations

Do not climb on or add stones to the cairn - it is causing real damage to an unexcavated monument. The summit is exposed with no shelter. The stepped trail is steep in its upper section.

Nearby

Strandhill is below the western side; Carrowmore is on the plain to the east.
