The Glamorgan Ridgeway Walk is a waymarked long distance path in South Wales which follows public footpaths, bridleways, forest tracks and minor roadways along the ridge line from Margam Country Park near Port Talbot to Caerphilly Castle. The 33 mile route is walked across wild upland and through picturesque valleys along the southern edge of the now disused South Wales Coalfield which is being redeveloped and rewilded. The walk offers views of the Brecon Beacons and across the Vale to the Bristol Channel to the south, with Devon and Somerset beyond. The route, from start to finish, visits Mynydd Castle, Mynydd Ty-talwyn, Mynydd Baedan, Bettws, Blackmill, Mynydd y Gaer, Mynydd Maendy, St Peter's Church, Mynydd Meiros, Mynydd Garthmaelwg, Llantisant, Taffs Wells, Craig yr Allt and Caerphilly.
Important note from a walker who attempted the Glamorgan Ridgeway Walk on Thursday 4th July 2018: "We walked part of the Glamorgan Ridgeway path today. It is in shocking condition. Signs either absent entirely or inadequate. The stretch from Blackmill to Bettws is choked with ferns and thistles and impassable. Very frustrating. If they are not prepared to maintain it, please do not advertise it as a genuine long distance footpath".
