I took a look at the news and it looks like you are more informed than myself :)

There has been a new, totally irrational law, that forbidden parking (not only camping but even parking) of campers practically everywhere, except motorways. Meaning that you may park to go to the supermarket and receive a fine. Crazy minds.

The Greek camper association has announced a lawsuit against that law but who knows how it will go.

To my experience though, they made this law so that camping or hotel owners can scare away wild camping from their territory and not for sending police in every isolated beach of Greece to find offenders. Nevertheless it is a very disturbing law...
