Exactly what we look for in a CL - just a field with water and rubbish/loo disposal.
Best to approach from the south to minimise travel on narrow roads and to spot the field's sign on the west side of the very narrow lane. The owner's house is 100 metres north of the site. We made the schoolboy error of using the satnav and then turning into Newsole Farm, which is a few hundred metres north. Site's owners were very friendly and polite explaining their location over the phone, which I'm sure they get fed up of doing.
Only downside is the road noise from the A2, which intrudes when sitting out, but not when inside the van.
