    Site Overview

    The Baia Underwater Archaeological Park near Naples is one of the most extraordinary dives in the world, a Roman city submerged by bradyseism. Divers swim among mosaic floors, statue bases, fallen columns and the foundations of ancient villas at just 5-15 m. Guided by licensed centres, the experience is both a dive and a journey through history, accessible to open-water divers and even snorkelers. The shallow depth, clear water and the sheer wonder of swimming through a sunken resort town make it unforgettable. The site rewards careful planning, good buoyancy and a respect for Italy’s marine-protection rules, and remains a favourite among Mediterranean divers.
