The cairn measures roughly 3.8 metres north to south and 2.8 metres east to west, rising only about 0.8 metres above the surrounding ground. Much of it has been absorbed by grass over the centuries, but along the east and west edges the stone perimeter breaks through, and on the east-southeast side there is visible kerbing, the remnant of a deliberate stone border that would once have defined the cairn's outline more sharply. A cairn of this kind is essentially a burial or commemorative mound, built by piling stones rather than earth, and they are found across Ireland in various forms from the Neolithic and Bronze Age periods onward.

What makes this particular spot quietly notable is that it does not stand alone. A second cairn lies approximately 14 metres to the east-southeast, suggesting that this hillside was deliberately chosen, perhaps repeatedly, as a place of significance. Paired or clustered cairns are not unusual in the Irish landscape; communities returning to the same elevated ground, with its long views down into a river valley, seems to have been a persistent habit. The Glantrasna valley below would have provided water, shelter, and passage, making the ridge above it a natural place from which to mark the dead or the landscape itself.
