Vourvouru Lighthouse 1 sits at the end of the Vourvourou lagoon in Sithonia, where the site reads as an easy-to-follow reef dive with seagrass, rock, and scattered pinnacles. It is the kind of place that works best when you stay slow and buoyancy-aware, because the terrain shifts from sheltered lagoon edge into a more structured reef band. Plan it as a relaxed local dive rather than a rushed swim. The marine life is steady through the year, and the route makes more sense on calm days when the water stays clear and the site’s simple layout can do the work.
