Pontneddfechan and Sgwd Gwladus

Waterfall Country has been particularly busy recently – why not explore another part of the Geopark or wider national park at the moment? If you do visit this area, to avoid accidents, please don’t be tempted to jump into pools. It may look inviting but the water is often shallower than it appears and there are hidden rocks just beneath its dark surface.

Beautiful walk beside the Nedd Fechan from behind the Angel Inn at Pontneddfechan with the spectacular Sgwd Gwladus at its end.

OS grid ref SN 900076 (parking) to SN 896093

The walk, much of it on the line of a former tramway serving the now abandoned silica mines along the route, takes about 40 minutes one way.
