In reply to dan bulman:
I take it you mean you found it down to the forest road (good effort in itself!), then struggled to find the path below that? Beyond the road, were you trying to find the public right of way (green line) or the actual footpath (black line)?
Not that it makes a whole lot of difference - having made the mistake of trying to follow one on a night time orienteering course (10 years ago...it's not recent), I've always avoided them since. Faced with emerging on the forestry road at that point a couple of weeks ago, I chose to mainly walk along the forest roads back to Gillerthwaite - a little longer (but not that much once you factor in needing to find a bridge), but a whole lot easier, and barely slower.
The cut through a couple of km further up the valley does exist, but neither does it save you a whole lot of distance.
