In reply to mic:
I was involved with Stew Wilson in checking and detailing many crags in the Durham / North Yorkshire area in the "North of England" many moons ago.
Not been back to the Denes - Castle Eden and Hestleden etc since then. Memorable moment when looking for (i think it was) Red Crag in Castle Eden Dene - but found it had fallen down !! Enjoyed Archangel - but the area is not a place to get excited about - but that was in the 1970's !!
Goldsborough Carr - however is in Durham - quite chuffed how this has been developed since we put it in the guidebook.
Had a good time a few years ago bouldering at Kenton Hill - just across the valley from G Carr which was a great little place.
Holwick Scar - not been since a friend was threatened by a farmer with a gun - in the 1980's !
Causey Quarry - is just in Durham (I think) - north of Stanley
Kepier Quarry - is near Durham - and because of that is probably worth visiting
There was (and possibly still is) Cleadon Crag - near Sunderland
Information on various websites.
The North Yorkshire Moors are not that far away - and well worth going to - they do overlook Durham
