This family-friendly gently sloping trail follows the wide flat route of the old railway lines that once carried passengers and coal the length of the valley.
23km of disused railway and forest road link the communities of Pontrhyfyen with Blaengwynfi and Glyncorrwg and wind through forest and open areas that were once railway sidings.
There is also a shorter 16km circular route from Pontrhydyfen to Cymmer and back. The old Cynonville station has been converted to a shelter and barbeque, and many other benches and picnic tables along the route offer opportunities to stop and enjoy the view.
Named as one of the five best cycle trails in the UK by The Independent (19/08/09).
