Tunnel Gricing in the Rhondda 

An old 8mm film of a trip with the Tunnel Gricing Society back in 1973.
Firstly a quick visit by coach to the Cymmer Tunnel at the Southern Portal, followed by a visit to the Rhondda Tunnel, walking through from Blaengwynfi to Blaencwm. Then a train from Treherbert to Pontypridd. Plans are afoot to reopen the Rhondda Tunnel to cyclists and walkers find out more here www.rhonddatunnelsociety.co.uk/
Switch on the subtitles.
