I am a member of www.wildcamping.co.uk ,if anyone is planning to cross the water and wildcamp then for £15 per year you can download all the wildcamping spots ,there are around 3500 places to camp,you are able to load the p.o.i. file onto sat navs and/or google earth ,just thought it might be helpful for you.It is also very helpful if anyone has any queries regarding their motorhome etc.
