Yurt camping close to a seaside, nr London

[CoucouCache]

Can anyone recommend a campsite with yurts, which is close to the seaside and not too far from North London please?
Would love to go to Devon, but not keen on driving more than a couple of hours.
Oh, and a dog-free site would be great.
TIA

this is our site. If you book direct with us then we throw in some free extras as we dont have to pay commission. About 7 miles from the Sussex coast, choice of wild and rugged, chic+trendy or beach holiday style depending which one you choose
you can PM me and I will send you details

Thanks NettleTea. Looks gorgeous.
Someone in RL recommended a place in Devon ... and though we initially thought it was a bit far, we went with it because we could camp in secluded woods.
Will definitely bookmark your link for future reference thought.

There are a couple on the Isle of Wight...

yes, there are not too many of us who have our yurts/domes actually in woodland. It seems a real marmite thing - some people love it some want to be out in the open. Personally I think there is nothing nicer than being in the woods round a campfire, so we went with what we liked, but popped one in the field and one on the edge of another bit of woodland as well for good measure (hoping to cover all bases!)
