It is easily missed: the structure measures only two metres across, its walls long since collapsed, with rubble scattered across the interior. A narrow entrance, less than half a metre wide, faces south-east, which is a common orientation in such structures, likely chosen to catch morning light while sheltering the interior from prevailing westerly weather.

Drystone hut sites of this kind, built without mortar by laying stone upon stone, are found across the uplands of Kerry and the wider west of Ireland. They were used at various points in Irish history, from the early medieval period onward, by people working the hills seasonally, tending livestock on summer pasture in a practice known as transhumance. The Erneen example sits in a hollow on a slope overlooking a river valley, a sheltered position that would have offered some protection from the wind. What makes the site quietly interesting is that it does not stand alone: a second hut site adjoins it directly to the west, suggesting this was a small cluster of activity rather than a single isolated shelter. Together, the two structures hint at a working landscape rather than a solitary refuge.
