By midmorning the boat slips out into the Toroneos Gulf and the shoreline of Sithonia opens like a map of hidden inlets. Pine-draped slopes push to the water’s edge, and the sea, a clear turquoise, dares you to leave the deck and float. Over the course of the day the trip threads swim stops at Robinson Beach and the Blue Lagoon off Diaporos — shallow, warm water framed by small pine-clad islets and sandbars.
