In reply to Gordon Stainforth:
Just to be clear there ARE a lot of routes here: 7 to 14m isn't a bouder problem in my book. My favorite limestone Mod is on this crag, some of the Diffs and VDffs are fab. However some rock on nearly every route needs care as some holds are snappy and some of the blocks risk blowing off (never ever use cams there on the edge of a block or on a flake), most lines can get vegetated and some get dirty as well (although most are cleanish at present). Also by VS you are hitting dirty sandbags in dangerous terrain (there is a HVD there like this though!). To add to the fun some bold top-outs have loose stuff.
Hence, Plesley just won't take the treatment that easier grit routes in the peak get. Lower grade leaders need to bare this in mind and drop a few grades. These are the reasons I just wouldn't recommend it at all for any inexperinced climbers or any outdoor groups. It's a super little bumbly venue though for routes and solos. Some kids groups do use the place but although the route choice I've seen them make is as sensible as it could be in the circumstances I still would'nt want to be in the group leaders shoes if a lump did come off and hit one of the children.
The bouldering there is excellent and pretty sound for all.
