There are still hidden paradises in Greece - Arsida, Σπηλιά Αρτζεντά

From Lavrio I took hitch and ran until Μαύρου Λιθαρίου (nude beach). From there I swam until the island Arsida, up to the amazing cave on the other side of the island
The cave have two saloons, the deeper one has no light and it is very narrow
The area has a very distinguished limestone, like dolomitas. Amazing place for deep water soloing, cliff jumping, diving or just relax and the calm beaches.
Respect the nature, you divide it with a lot of birds
