Oblong and complex multiple enclosure hillfort located on the broad W summit of a prominent E-W aligned ridge (Cwm Cefn y Gaer- Atlas No. 1377 is on the E peak) overlooking the River Ithon and head of a stream on SE flowing into the River Ithon. Steep surrounding slopes to N and S, moderate to E along ridge, moderate then steep to W. Interior area of whole site c. 0.67ha. Ramparts follow the contours. Defined by main inner enclosure on SW of the site, with remains of a possible incomplete annexe or enclosure on its NE side. Possible inturned entrance on its NE side. Outer bank surrounds both on N, SW and NW, and again seems incomplete with nothing on SE and S. Possible counterscarp on part of its W side and possible inturned entrance on its far NE. No evidence for ditches. Rough grazing and generally well-preserved. On 1st Ed. OS map (1889). Minimal investigations, undated.
