The monument sits in hilly terrain, with Crockkinnagoe mountain rising to 364 metres just 1.2 kilometres to the east. From the tomb, views are limited except towards the southeast, where the River Termon valley opens up towards Lower Lough Erne, roughly 7 kilometres away. The location feels remote and atmospheric, surrounded by heather and furze that have colonised the southern portions of the ancient cairn.

The tomb itself consists of a gallery chamber preceded by a partially concealed court, all contained within a substantial oval cairn measuring 23.5 metres long and 13 metres wide. Peat covers much of the structure to a depth of 10 to 15 centimetres, though the stony nature of the cairn is visible where the surface has been disturbed around the gallery. The northeastern section has suffered from stone robbing; the pilfered material was repurposed to build two field fences, one running alongside the cairn and another extending southeastward from the gallery entrance. The gallery chamber stretches 6 metres in length and varies in width from 2.2 metres at the entrance to about 1.5 metres at its midpoint, before widening again towards the rear. This deliberate narrowing suggests the space was originally divided into at least two separate chambers.

The entrance to the gallery features two jamb stones flanking a lower doorstone, topped by a substantial lintel slab measuring over 2 metres long. While the tomb has lost its roof stones, impressive corbelling survives along both sides of the gallery, with multiple tiers of overlapping stones that would have helped support the original covering. In 1981, security operations led to partial clearance of the front third of the gallery, during which a large flint knife was recovered from the spoil; a tangible reminder of the tomb’s ancient purpose. The surviving orthostats, or upright stones forming the gallery walls, stand up to 1.6 metres in exposed height, with a backstone marking the western terminus of the chamber. Despite centuries of weathering and disturbance, the monument remains an impressive example of Neolithic engineering, its careful construction still evident in the precisely positioned stones and surviving architectural details.
