Looking at the restrictions, it's not clear whether St Bees bouldering is open at the minute.
Bird ban on bouldering south of Fishermans steps, but on St. Bees Head there's mention of a landslide. Is the ban on just the routes, or bouldering as well?
"Restricted Access
The main bolted areas (Apiary Wall and Scabby Back) are unrestricted. All other areas of the crag including Fisherman's Steps are restricted."
