The three round cairns at Blaen-y-Cwm are located in a saddle at 410m above sea level aligned with, and on the east side of, a mountain trackway running north from Cefn Moel to Mynydd Llangorse. The three are close-set in a north-south line. All are turf-covered and, aside from the southernmost which is marked by a central excavation, relatively undisturbed. A footpath passes between the two southern cairns.

This cemetery lies within 1km - 2km of several contemporary ritual and funerary sites and therefore constitutes an important element in a wider prehistoric landscape. This site is unusual, however, in that it comprises three substantial mounds in a close-spaced grouping. Aside from the upper part of the southernmost cairn, they are well preserved earthworks with considerable potential for revealing structural features, burials and buried land surfaces.
