Here you will need to leave the canal, and cross under a bypass into Maesygwartha where there is a lovely path through the woods, over a bridge, then up a steep ban to the road which then passes under the main A465 into Clydach. Here you can either take the hill up Quarry road, or there is a path into the nature reserve at Coed Ffyddiwn, where it is well worth taking a detour up the river to see the waterfalls. There is then a steep push up a gravel path to re-join quarry road . On the right you will see Sustrans route 46 along the old railway to Brynmawr.
