I will speak to my contact up at the Silverwood Scout Camp, they have it opened up for a biker weekend every year so I don't see why it couldn't be opened for a bushcraft weekend. Only problem is that the scout camp itself doesn't own the surrounding woodland, and there isn't a lake to speak of anywhere near it like Delamere. On the upside, the other side of the fence is where I shoot rabbits and I saw a kestrel up there the other day, and I have seen a fox there aswell, along with an owl and a couple of pheasants.
Mainly, I think it would be a good site for practising skill sets other than bumming around in the woods. The woods next to the camp are open to the general public and as a result they use it to walk their dogs. many don't clear up, so it's a dodgy bit of woodland, OK in the colder months as many don't go up there but during te summer it seems to be a bad area for dog mess. The camp site itself is good though. I'll try and get some pictures up.
