I've just found this:

Its not quite an mtb trail, but it is a bridleway that makes use of an otherwise pretty un-rideable section. The more that come, the better it will be. It hopefully represents the thin-end-of-the-wedge in respect of dialogue with the AONB, so it would be great if some of the regulars could turn out.
