Writer Sean James Cameron sent these photos of his favourite walk. The path traces the journey of the Taff Vale Railway in the days when it travelled from Treherbert station to Blaenrhondda station, through Blaencwm on to Blaengwnfi.
Start the walk near Wyndham Street in Tynewydd. Take the lane by the post office until you reach a large open space.
