The Tarbert ferry road cuts directly through this cashel, slicing across its southern to eastern arc and separating the monument from part of itself. A cashel is a stone-built ringfort, a type of enclosed farmstead common across early medieval Ireland, and this one has survived the indignity of a modern road with more presence than might be expected.

The fort is univallate, meaning it has a single enclosing wall rather than the multiple concentric ramparts seen at higher-status sites. That wall forms a roughly circular enclosure measuring about 44 metres north to south and 43 metres east to west, large enough to have sheltered a household, its livestock, and whatever outbuildings were needed for daily life. Externally the bank still rises to 3.2 metres in places, which gives a real sense of the original intention: this was a boundary that announced itself. Internally the height drops to around 1.4 metres on average, and access to the interior was through a stone-lined entrance passage to the southwest, about 2.5 metres wide and nearly 7 metres long. That kind of formal, tunnel-like entrance is a characteristic feature of cashels across Munster, designed as much to control movement as to provide defence. The site lies to the east of another fort known locally as Stranavaun, suggesting this stretch of north Kerry once supported a settled, organised landscape of enclosed farmsteads sitting within sight of one another.
