What makes the example at Kilcolman on the Dingle Peninsula quietly anomalous is its pair of opposed entrances, gaps to the east and west that break the usual uninterrupted circuit of the enclosing bank. Most ring barrows present a continuous boundary; this one was designed, or at least used, with deliberate access points built into its form.

The monument measures roughly 18 to 19 metres across overall, though its central mound has been altered over time. Local information recorded in J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region indicates that stones were quarried from the interior at some point, which has distorted what was probably once a roughly circular mound into an irregular shape now measuring approximately 7.4 metres north to south and 10 metres east to west. The fosse is shallow, ranging from just 10 to 30 centimetres in depth and between half a metre and one and a half metres wide. Along an 8-metre stretch of the northern bank, the outer face is reinforced with low drystone walling, a detail that suggests some deliberate maintenance or construction effort at that section. The bank itself reaches its greatest internal height of just over a metre immediately north of the eastern entrance. Whether the entrance gaps were originally bridged by causeways across the fosse is unclear; any such features may have been obscured by the same disturbance that reshaped the mound.
