We just got back from a lovely week there, it is a stunning 70 acre organic/green campsite and not as busy as I thought it might be. It is a magical place! The children loved it!
We got so many compliments about our bell tent too....
The price was good too, £17 per night for family tent, 2 adults, 2 kids. Lovely warm showers too and extremely clean washing up areas. So much to do on site, rope swings, piglets to visit, little woods for the kids to play in. Watch out for tics though, my DH go one and we went to the nearby hospital to have it fished out properly.
My 3 year old refused to use the composting loos though LOL
You can have campfires in the fire pits there.

There are two ponds though so if you have younger children it probably isn't best to let them to run too free/let them completely out of your site. IYKWIM. One of the ponds is in the woods next to one of the rope swings.
You can camp in wild flower meadows there too...It really was beautiful! I think it got number one in Cool Camping? I can see why now I have visited it.
