In reply to JMarkW:
You can always find peace and tranquillity up there - as with Stanage, the only thing you have to do is stretch your legs a bit. I've never seen Skyline busy, ever, and I suspect the same applies to the Clouds. Likewise Hen Cloud (when it's not bird-banned).
As always, getting further than ten minutes from the car almost guarantees quiet, even on quality routes.
