David, Helen and I will be going tonight. The crag has been seriously cleaned up a few years ago, is nice and sheltered from the west wind. Take the A632 Chesterfield to matlock road, after Kelstedge go down then up the big hill. Near the top small road on left signed for Wooley. Park about a mile on just after the Old Engine farm. Its in the Froggatt to Black Rocks guide under Amber Valley.
