As part of a recent seaside camping holiday in Sithonia, Chalkidiki’s idyllic middle peninsula in the north of Greece, I spent a day cruising around the small but splendid Diaporos Island. The Aegean island’s dozens of sandy beaches, quiet coves and rocky headlands are surrounded by crystal clear turquoise waters and tiny islets – all yours to explore any way you see fit, you’re the captain for the day. Just bring some basic snorkeling gear to fully appreciate the Mediterranean’s underwater environment… and choose your own adventure!
