Small contour hillfort on summit of rocky crag overlooking coastal plain above Barmouth and sea. Precipitous surrounding crags to SW and very steep to NW, craggy hillside upslope on E. Measures 60m N-S by 48m with internal area estimated at c. 0.1ha.

Most of walls collapsed or robbed of stone. Craggy rough upland grazing and bare rock. Not scheduled. Few details. Minimal investigations, undated.
