Known locally as Clochán Dréimide, the site consists of two conjoined clocháns, the beehive-shaped dry-stone cells associated with early Christian and medieval settlement across the Dingle Peninsula, linked by a communicating passage and accessible from outside through an entrance on the south-east side of the southern structure. The cells are modest in scale, measuring roughly 2.3 metres and 2.5 by 1.1 metres across, and survive to about a metre in height. A short distance downhill, the partial remains of a D-shaped dry-stone chamber survive, and further ruined structures lean against an old field wall some ten metres to the west.

The Dingle Peninsula, or Corca Dhuibhne in Irish, is unusually dense with dry-stone remains of this kind, a consequence of its relative isolation and the durability of the local stone. Clocháns were built without mortar, their corbelled walls carefully laid so that each course of stone projects slightly inward until the structure closes at the top, a technique that can produce remarkably weatherproof interiors. The grouping at Gleann Fán, with its conjoined cells and associated field wall, suggests a small settlement or seasonal agricultural enclosure rather than a solitary hermit's cell. The site was recorded and described by archaeologist J. Cuppage in the 1986 Dingle Peninsula Archaeological Survey, which catalogued the extraordinary concentration of monuments across this part of Kerry.
