In reply to spidermonkey09:
According to the BMC RAD looks like should be ok this year:
'Restrictions apply from 15 February - 31 May.
Reason: Nesting Birds
The restriction applies to Crag X - the esoteric crag in the woods at the northern end of Langcliffe Scar.
The previous restriction for climbing in the quarry is not in place this year as birds have failed to nest.'
