The fort sits on a prominent ridge near Tahilla on the Iveragh Peninsula in South Kerry, and its double ring of earthen banks, making it a bivallate rath, gives it a more elaborate defensive profile than the single-banked ringforts that are far more common across Ireland. The interior measures roughly 21 metres north to south and nearly 24 metres east to west, and is now covered in cultivation ridges, the low parallel earthworks left by generations of spade or plough farming long after the fort's original occupants had gone.

The outer bank lost its southern section in the late 1970s, when it was levelled and the fosse between the two banks was largely infilled. A fosse is the ditch dug to create the raised bank alongside it, and what survives of this one runs to about 2.6 metres at its base. The inner bank is considerably more substantial, rising nearly 5 metres above the surrounding ground on the outside and dropping about 75 centimetres to the interior. Trees growing along its crest have added to its erosion, slowly pulling soil and material down into the fosse below. The original entrance into the fort was through a gap in the eastern side of the inner bank, where a causeway crosses the fosse. As for the souterrain, a writer named Graves described it in 1930 as consisting of the usual underground passages leading into chambers, a formula that suggests he had seen or heard enough of these structures across Kerry to regard this one as fairly typical. Whether the slabs recorded in the Schools' Collection still mark the opening, and whether anything of those passages remains intact beneath the ridge, is not clear.
