Glamorgan Ridgeway Walk

33 miles (53 km)

Follow the Glamorgan Ridgeway from Margam Country Park, near Port Talbot, through beautiful upland and valley scenery, to Caerphilly Castle. There are fabulous panoramic views of the Brecon Beacons to the north, the Bristol Channel and Devon and Somerset to the south.
The walk begins at the splendid Margam Country Park (video below). The attraction includes the magnificent Margam Castle, an 18th Century Orangery with ornamental gardens and the Deer Park, all set within1000 acres of beautiful countryside. From Margam you begin by heading east to Bettws and Blackmill. You then pass through Llantrisant forest, Llantrisant, Garth Hill and Caerphilly Common. From Garth Hill there are fine views of Cardiff and the Taff valley. It is thought to be the inspiration for 'Ffynnon Garw', the fictional mountain (or hill) featured in the book, and film, The Englishman Who Went Up a Hill But Came Down a Mountain. The walk also passes near to Taff's Well - the only thermal spring in Wales located in Taff's Well park. You also climb Caerphilly Mountain with more tremendous views to enjoy as shown in the latter part of the video below.
The final section descends into Caerphilly, finishing near the castle.
