Complex partial contour hillfort located on W-facing slope of limestone crag/outcrop above the Vale of Clwyd and River Clwyd at its confluence with the Afon Hesbin at Efenechtyd. Moderate to strong to N and E, moderate to S, precipitous on W. Opposite Pen y Gaer, Efenechtyd 1.5km away (Atlas No. 1183). Measures c. 154 N-S by 54m, with internal area c. 2.7ha. Defined on W, and sub-divided internally, by series of N-S precipitous cliff-lines, resulting in two distinct enclosures, one below the other, both delineated by simple banks, doubled at S end of E upper enclosure, each with inturned N-facing entrances. Much vegetation growth makes features very difficult to distinguish on site. Rough grassy bracken and scrub, woodland and bare rock. Butterfly conservation area. On 1st Ed. OS map (1874-75). Minimal investigations, undated.
