Achaea’s beaches await the keen swimmers to be initiated in the secrets of the sport. A rich underwater flora and fauna is hidden in the waters of Patraikos and Corinthian bay. Divers are bewitched by the unknown, exploring old shipwrecks as well as clusters of rocks and reefs which host a great variety of sea organisms, starfish, shells and different kinds of fish. In Patra operate diving schools, with experienced trainers which you can contact.
