“Cwm Câr, a small tributary valley of Tâf Fechan just south of Pont Dolygaer, is a place I return to frequently. Once I followed the stream, Nant Câr Fach, from Pontsticill reservoir to it’s junction with the Taff Trail – an exciting and difficult route but not recommended!

There is an easy forest track north of the stream (Taff Trail) with great views of Ponsticill reservoir and surrounding hills and Cwm Callan opposite. This track has a weird section of tarmac before a bridge which crosses the stream. Many people pass here and miss the highlight of the valley.

Three streams tumble down off Tormwnt (Rhyd Ddu,Trawsnant and Câr Fach) to form a magnificent group of falls hidden from walkers and bikers. Sometimes the blandest of hills such as Tormwnt have the greatest treasures.”

Martin led a walking tour of the Taff’s sources with the Living Taff a while ago. He has an incredible knowledge of the area; having spent a lot of time looking after the paths so many use to reach Pen y Fan.
