The Cwm Prysor viaduct which crosses the Afon Prysor (river) will come into sight after a short while. It is 120ft high and has nine arches.

Continue west along the well defined trackbed. There really aren't many further directions other than to keep going. There are a couple of sections which can be particularly muddy at all times of the year it would seem.

There were a couple of station platforms along the route which are no longer to be seen, and a small brick hut. At the end you will find a stile leading on to a small road leading off the main road. Although the Ordnance Survey map indicates that the line continues, it wasn’t obvious if this is easily accessible or indeed permitted.
