Cefn Hirgoed is a ridge in Bridgend county borough in South Wales. The ridge extends for about 5 km east from the village of Sarn just north of Bridgend to Pen-prysg north of Pencoed. At the point where it reaches its highest elevation of 142m, are a couple of covered reservoirs. Towards the west the M4 motorway runs along the hill’s southern edge.
Geology
The hill is formed from relatively hard-wearing sandstones of the South Wales Lower Coal Measures with mudstone layers between the sandstones which here dip steeply northwards into the South Wales Coalfield syncline.[1]
Access
Almost the entire hill is mapped as open country under the Countryside and Rights of Way Act 2000 giving a general right of access on foot to the public. It and the adjacent Hirwaun Common are also crossed by several public footpaths. A couple of minor roads, Heol Spencer and Heol Llan/Heol-Las, run north-south across the ridge.[2]
