It is not dramatic. The ground simply lifts a little, defined by a gentle scarp no more than 0.8 metres high along its northern, southern, and eastern edges, and the grass over it grows the same as the grass around it. But press a foot against the turf and the ground feels different beneath, and in places the sod has thinned enough to reveal what lies underneath: large blocks of limestone pushing through.

The mound is sub-circular in plan, measuring roughly 11.6 metres north to south and 5.3 metres east to west, dimensions that put it in a bracket familiar from other earthworks recorded across the Irish midlands and west. Mounds of this general character can represent anything from burial cairns to the collapsed remains of early medieval ringforts or enclosures, structures that once organised farmland, livestock, and sometimes ceremony across the landscape. The limestone blocks visible at the surface suggest either deliberate construction using local stone or the remnants of something more substantial that has since subsided into the earth. Cahernarry itself, a name derived from the Irish for a stone fort, hints that this part of County Limerick had a long history of such enclosed settlement, though the mound's precise origin and date have not been formally established.

The site sits immediately east of a field boundary on higher ground, which means it can be spotted from a distance if you know the shape you are looking for, a subtle swelling in an otherwise even slope. Access depends on the usual considerations of rural County Limerick, meaning landowner permission before approaching across private farmland. There are no markers or signage. The best time to visit is late winter or early spring, when vegetation is low and the limestone blocks are most legible through the sod. Once there, the scarp is subtle enough that walking the perimeter slowly is the most reliable way to read the shape, particularly along the northern edge where the drop is clearest.
