There is no longer a restriction at Hidden Quarry (formerly Darlton 2) as the birds have moved to a different location this year.
In not unrelated news, there is now a restriction at Goddard's Quarry down the road. Please avoid the Western end of the quarry - all routes on Sunshine Wall and the Upper Tier.
There's a chance this may change again in the near future, depending on how the session progresses, so please keep an eye on the RAD.
Thanks.
