I'm also looking and found a few lakes close to calais
val Dore lakes
blues lakes a(in Belgium but only 2 hours from calais)
and
barnview lake
these all look good and reasonably priced
It was freezing. Didn't see a Marshall for hours. Zipped up the bivvy to have a dump in the bucket and carrot man (Marshall) opened the door as I was mid drop! "Is the kettle on nige"?
"It's not that what you can see steaming carrot man"!!!!!!! Lol
