Heavily weathered and sub-rectangular in shape, the stone rises to 1.9 metres and measures 2.5 metres by 1.4 metres at its base, narrowing as it climbs. Its long axis runs east-northeast to west-southwest, an orientation that may or may not be coincidental, depending on what questions you bring to it.

Standing stones are among the most common and least understood monuments of prehistoric Ireland. Erected singly or in groups during the Bronze Age, they served purposes that remain genuinely uncertain, with theories ranging from boundary markers and burial indicators to astronomical alignments and ritual focal points. What makes the Ballyarra stone quietly arresting is its relationship to the surrounding landscape. From where it stands, Corrin Hill is visible to the northwest, a prominent ridge that would have been a recognisable feature of the local horizon for thousands of years. Whether the stone's placement was chosen with that hill in view is impossible to say with certainty, but the visual connection is there, and it is difficult not to notice it.
