Penwyllt Mountain Tracks Dog Walk Information
An alternative walk if you are not willing to do the one and a half hour circular walk, is simply to continue along the straight Brecon to Swansea railway tracks. You can walk three or four miles in a straight line, on the level, no hill work at all, keeping the Upper Swansea Valley and at times the road below, in view. Once you have had enough of going in one direction, you simply turn around and walk back again.
If you kept on walking northwards you would eventually come out on to the A4067 Swansea to Brecon road that passes by the Castle. The track itself peters out though it does resume at later points - not really walkable further along as it passes through farm fields.
The picture in the above photo is of the Upper Swansea Valley as seen from the railway line heading South back to Penwyllt. The photo is at an angle but you can clearly see the A4067 road on your right here; this leads back to Craig y Nos Castle but you do not want to walk along it as the road is busy and you will not get back to your car once you have dropped down on the main road.
