misshardbroom not that I'm stalking you but another campsite I might book! Where do you do your research for campsites? Tried to get into Cotswold View for a weekend in August but only one night available.
That's OK, I'm incredibly flattered that anyone should think I'm a source of good camping knowledge, with my crappy outgrown tent and single burner!!
Cotswold View was recommended to me by a friend (actually, OP, there's another one for you), and then I just found this one myself because I did an internet search for 'country park camping Somerset' and up it popped!
The other one I'd massively recommend which is probably 1.5 hours or so along the motorway from Bristol is Wellington Country Park near Reading, we had such a brilliant time there (which inspired the search for 'country park camping').
