Small, sub-oval, multivallate inland promontory fort sited against steep, craggy slopes on S and W and at the edge of level ground on the E of a steep- sided valley. Opposite to Nant-y-Castell hillfort (Atlas No. 1679) above Llanbedrog and the beach. Surrounding slopes moderate on NE, steep on S and very steep/precipitous on W. Measures c. 76m NNE-SSW by 57m, with internal area 0.38ha. In angle formed by two cliffs on the W and S three lines of crescentric banks on the E and NE define site from main plateau. Innermost bank originally stone revetted. No ditch. Entrance on E. Scrub and bracken cover and recent wall make interpretation difficult and no interior features defined. Minimal investigations, undated. A
