The substantial stone monument, measuring roughly 23 metres north to south and 15 metres east to west, rises up to 1.5 metres high on the summit. Built from loosely heaped large stones and boulders, its oblong shape was cleverly adapted to fit the available space on the hilltop, merging naturally with the slopes on its southern and western sides whilst standing proud from the breaks of slope to the north and east.

The cairn overlooks a dramatic setting where boggy ground stretches northeast towards a sea inlet and coastal lowlands, with the distinctive peak of Errigal Mountain visible on the distant horizon. To the west, Aghnish Lough dominates the view, nestled in a natural hollow bordered by steep, rocky ridges covered in heather and sedge. At the northwest end of the lough, a small promontory fort occupies a jutting piece of land, adding another layer of ancient history to this atmospheric location.

Time and curious visitors have left their mark on the monument; several circular depressions dot its surface where stones have been disturbed or removed over the centuries. On the northwest side, someone has repurposed cairn stones to construct a low wall defining a small circular space about 2.5 metres across, open to the west. Today, the outer edges of the cairn are cloaked in mossy sod and heather, whilst bracken conceals much of the structure for large parts of the year, lending it an air of mystery as it continues its silent vigil over the Donegal landscape.
