This was a walk that I led, visiting a site in the nearby Dechmont.
The whole site is impressive, with massive beautiful buildings that are no longer used and fall into disrepair. From the information board it seems that they are planning to redevelop some of the buildings to convert them into flats and there will be also conservation area, which would be great.
At the moment, it is popular with dog walkers and thrill seekers.
The walk took us about 3 hours, was enjoyed by all of us and was really atmospheric with heavy clouds hanging above us.
