Diaporos Island sits just off Vourvourou on Sithonia, close enough to reach by small motorboat or kayak. The appeal is simple: pine-fringed coves, clear water, and quiet beaches that feel far more remote than they are.
Boat rental is the usual way to see it, and in high season it is worth arranging one ahead of time. Go early, bring water and sun protection, and treat the day as a slow loop through the coves rather than a single beach stop.
