In reply to Longsufferingropeholder:
It was unclear, I wish I'd taken a photo now - I did ask a few people, including some instructors from PYB who said the whole of the main face was closed. I can't say whether this is correct or not but no one was climbing on it whilst we were there.
A local couple admitted they had climbed on the main face Saturday (as everyone was) but they weren't going to again to avoid jeopardising access.
It would have been easy to 'ignore' the second red post to the right of the crag and climb the routes to the right of the barrier - will email the BMC rep so they can clarify as would be a shame not to climb those routes if you can
