[2] The hill has the form of a broad ridge aligned south-south-west to north-north-east peaking at an altitude of 632 m. It has a subsidiary top to the north which is known as Fan Dringarth and which attains a height of 617 m. Its broad northern ridge is eventually truncated by the cliffs of Craig Cwm-du.
A number of features of archaeological interest are to be found on its flanks including several house platforms.
Rock exposures are infrequent − the hill being draped with glacial till and accumulations of peat.
The hill is within the Fforest Fawr Geopark designated in 2005 in recognition of the area's geological heritage.
The entire hill is designated as open country so walkers may wander at will though most choose to ascend the hill from the Natural Resources Wales car park at Blaen Llia (OS grid ref SN 926165) just off the minor road between the villages of Ystradfellte and Heol Senni.
