In reply to Gerry:
> I think you'll find that wild camping is illegal just about anywhere at present; something to do with a pandemic that's been going on for over a year now.
Not true I would have thought. If you're on your own, or with a member of your household, it's permitted, in England at least, from 12 April this year, and for much of last year. It surely counts as "self-contained camping". The COVID risks are minimal, apart from interactions with others on the drive to and from the area. And we are now permitted to do that.
I'm certainly not ignoring or underplaying COVID, as your post could, I think, be taken to suggest.
