...IMO.
A good choice of newer style sites around Kent and E Sussex which offer camping in the woodland, 'pitch where you like', non-crowded non regimented camping, but you have to book a long while on advance to get a space. And in other parts of the country this sort of place can be almost non-existant.
Camping seems to be enjoying a huge boom - is there a way to let farmers and landowners know that there is a gap in the market?
