From the outside, the enclosing bank still rises to about 1.25 metres above the surrounding ground, enough to suggest its original purpose, even if centuries of rain and livestock have softened its profile considerably. These circular enclosures, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically serving as farmsteads enclosed by one or more earthen banks and ditches. Thousands once dotted the landscape; a great many survive only in this kind of reduced, half-legible condition.

The site at Ballynarooga Beg measures roughly 25 metres across its east to west axis, enclosed by an earthen bank with an external fosse, the shallow ditch that once reinforced the boundary. The fosse here is recorded as about 0.3 metres deep and 1.2 metres wide, modest dimensions that suggest either a single-phase enclosure of moderate status or simply the result of prolonged erosion. The interior is level and lies under rough grazing, as it has for a long time. The survey was compiled by Denis Power and uploaded in August 2011, drawing on field observation rather than excavation, so what lies beneath the surface remains unexamined.

Accessing the interior is straightforward in practical terms, though not necessarily by design. A gap of about 1.2 metres in the bank on the east-south-east side has been identified as most likely caused by cattle rather than representing an original entrance, and the bank itself shows considerable erosion from the same source. Visitors should expect an active or recently grazed field, and the usual considerations around farmland access apply. The rath sits on a slight south-facing slope, so the outer bank reads better from downhill, where the full exterior height is more apparent. There is no formal access, no signage, and no infrastructure; the site is one of those that exists quietly in the agricultural landscape, neither protected nor particularly advertised.
