Ah! The very same BigSweetie took us there in July. To be honest (and to admit this here may go down as heresy ) it blew my mind more than the stones! To touch something that is STILL ALIVE after all that time was freaky and wonderful and quite profound.
... me and Mrs Wiggy visited the "oldest tree in Crete" this summer. There were late Minoan rock-cut tombs, and a holy spring just yards away. No one else there. Magic!
