Remains of a linear earthwork known as Senghenydd Dyke stretch across the southern side of the hill.

It is considered to mark the edge of an extensive 13th-century deer park associated with nearby Caerphilly Castle.

[2][3] The summit area of the hill is mapped as open access under the Countryside and Rights of Way Act 2000 thereby giving walkers freedom to explore it on foot.

There are additionally a couple of byways which traverse the eastern and southern margins of the summit plateau.

The unfenced minor public road from Nelson to Senghenydd runs along the northwestern margin of the hill.
