This cache belongs to the REALLY SideTracked series. It is not designed to take you to a magical place with a breath taking view. It's a distraction for the weary traveller, but anyone else can go and find it too. More Information can be found at the SideTracked Website
A remnant of the old road complete with old railway bridge makes a perfect trainspotter's hang out. There's a worn patch further up on the left where they stand to use a fence post as a tripod. This is the main Swansea to Paddington line, but also takes local trains.
Cache is a nano in a host, I put it this side so you can check each way for dog walking muggles and incoming trainspotters, please replace exactly as found, and don't add any images of it to your logs.
