pretty much all of them you can drive virtually into, the one that is over the river at bollihope you can\'t drive up to any more as there\'s some large boulder blocking the track... there was always loads of divvy\'s (jesmond jet set) trying to to go up and getting stuck in the cheap jap 4x4\'s, I used to get me tranny van up no bother!
a lot of the bollihope ones are blocked a short way off the road, but they\'re nearly all litterally at the road side anyway with loads of parking
you used to be able to drive into the old mine workings at nenthead but not been up there for a year or 2
not many quarries woth climbing in weardale (no good exposed faces) some of the best currently are at bollihope I\'d say, although, since the cement works closed the workings there are due to be opened up to \'leisure\' activities whatever that entails, and that is a huge quarry, but a a bit of a trek up to it unless they let you use the track the quarry wagons used.
there\'s a great place we used to climb at consett - hownsgill quarry, at the bootom of the dip from consett into castleside, turn left there and go under the old viaduct, the quarry itself is now densly wooded but there\'s some big caves under the quarry faces
I\'ll have a think and see what else I can suggest. If its rough ground type of thing them there is any number old lead mines out here that might fit the bill
