They definatly mean the miners path, I can't think of any zig zag that prominent on the horizon. I'm not sure about lighting it though, could attract some unwanted attention, i think they should maybe concentrate on preserving it first, or investing the money into the highstreet. And if they do install lighting, maybe they should think about doing something similar with the Wrysgan incline, as that really is a prominent feature that can be seen for miles.
