More good news. The farming Co-Op on whose land Back Bowden and Bowden sit have confirmed they have no problem to folks using the crags (Note this in Bowden's case is Bowden north of the Triple Cracks stile). I am in the process of tracking down the farmer on whose land the southern section of Bowden and the usual approach lies. Until I confirm otherwise please do not use or approach Bowden via the normal parking and gate and avoid climbing south of the stile.
All of the other usual Covid related advice remains.
