There's Fordell Firs near Inverkeithing. I think people can camp there anyway.... Scouts and schools do all their camping stuff there. Just a short hop across the Forth on the train to Edinburger.
Another nice site is Witches Craig, at the foot of the Wallace Monument in Stirling. Not particularly handy for Edinburgh, but not a million miles away either.
Around Edinburgh itself, I'm not sure..... there are probably campsites in/around the Pentlands just South of Edinburgh.... maybe around the Roslin/Hillend areas???
Enjoy your trip to Auld Reekie
