The banks are modest, rarely more than thirty centimetres high and around a metre across, and the full layout can no longer be followed on the ground. What survives is fragmentary, the kind of thing that registers more clearly from the air than underfoot, and indeed the site was formally recorded through aerial photography rather than ground survey alone.

The field system is laid out on two rough axes, running broadly north-northwest to south-southeast and west-northwest to east-southeast, a pattern consistent with deliberate land division rather than casual clearance. The boundaries define a series of rectangular and subrectangular enclosures, a field shape common across prehistoric and early medieval Ireland, where communities parcelled land for cultivation or grazing using whatever combination of stone and earth was locally available. What makes Farranyharpy particularly worth attention is the density of associated remains in the immediate area. One of the field boundaries is butted by a possible enclosure, meaning a later or contemporary structure was built directly against it, suggesting the landscape was used and reused over time. Towards the eastern end of the field system, another enclosure has been identified. Then, roughly two hundred to two hundred and fifty metres to the south, the concentration deepens further: a megalithic structure, a cashel (a type of stone-walled circular enclosure, typically of early medieval date), a further enclosure, and yet another field system. Together these features point to a patch of hillside that was, at some point or across several points in prehistory or early history, a genuinely busy and organised human landscape.

The site sits in present-day pasture, and the earthworks are low enough that they blend easily into the texture of the ground. The terraced slope of Red Hill provides a natural framework that would have made this land attractive for early farming, offering some shelter and drainage on the west-facing gradient.
