In reply to PaulJepson:
I've taken a few days off work when there's been good weather and it's been rammed, much worse than a usual sunny weekend this time of year. I've heard weekends have been even worse, with queues on most routes, although I haven't been.
That said, a large cohort of people there were local climbing wall staff, as they were all on furlough - now they'll be going back to work the crag could be less busy. Not having a dig at them at all btw, in their situation I'd probably do the same.
