Which guide would you recommend for bouldering in Northumberland?
The guides that are out there seem to have been around a good while. I have the first edition of Boulder Britain, so that might do. It would be my first time up there.
There are quite a lot of free topos on FB, look for "The Quiet County", which bring the NMC printed guide pretty much up to date, except for the new desperates on the venues in the guide.
