Diaporos is an island, opposite Vourvourou, less than 10 km from Agios Nikolaos of Sithonia municipality. It extends to 3.2 m² and has an enormous natural trick of 700 meters and more length, which is useful as a mooring location for boats, when the sea is rough. The gulf leads to shallow waters that remain always warm and are suitable for winter swimming. Most of the island is covered by a pine forest.
