I walked the first part from Cwm Mawr (link to history) near Drefach to Pontyberem on the 19th Feb. As this is a linear walk I also walked back!
My companions were Ollie and Finn from Many Tears Rescue Centre.
The walk is easy and in good condition and mainly stays in the countryside passing a few farms. The route would be OK for bike riding but not road bikes as it is a little rough in some places.
I continued the walkon 26th Feb from Pontyberem to Pontiets and back. Again an easy walk in quiet countryside. Today I had another dog, Hurley, my friend's son's springer spaniel.
You can see from the above picture the path is very straight in places.
Part way along the line there was obvious signs of old industry which I assume related to mining and at one spot a lonely signal.
From Pontiets there is a Mining heritage Trail which will be the next bit to be walked.
