Its 470m high summit is marked by an ancient cairn known as Carn-y-Pigwn, on which is a more recent trig point.

Much of the hill is cloaked by modern forestry plantations though its southwestern flank between Porth and Ferndale has not been coniferised.

The earthworks of a Roman camp remain on the ridge at OS grid ref ST 002982.

[1][2] Minor roads ascend the slopes of the hill from Ferndale, Ynysybwl and Pontypridd converging at the elevated hamlet of Llanwonno.

Route 47 of the National Cycle Network runs the length of the hill on its eastern side ascending via the minor road from Pontypridd to Llanwonno and then continuing northwest on forest tracks to join the A4233 above Maerdy.
