The site sits three fields to the south-east of a neighbouring enclosure, its western flank left undefended by walls because a steep glen does the job instead. This kind of stone enclosure is known as a cahir, essentially a ringfort built from dry-laid stone rather than earthen banks, and the crescent shape here is relatively unusual, shaped in part by the natural contours of the terrain.

The enclosing bank, now grass-covered, still reads clearly in the landscape, rising roughly a metre on its interior face and a little less on the outside. Two openings survive: a narrow gap of around 3.4 metres to the south-east, and a slightly smaller break of 2.6 metres in the enclosing bank itself. Inside, the three clocháin, as beehive huts are known in Irish, are built tight against one another. These corbelled stone structures, constructed without mortar using carefully layered flat stones that project inward course by course until they meet at the top, were typically used as small dwellings or ancillary buildings, often associated with early Christian monastic activity or secular farmsteads. The stonework at Tiduff is largely buried under vegetation, though the northernmost hut still exposes some of its original drystone walling. The interior of that hut measures roughly 18 metres north to south, about 8 metres east to west, and stands somewhere between one and just over three metres high. The site was recorded and described in C. Toal's North Kerry Archaeological Survey, published by Brandon in 1995.
