Our 3-hour tour is an adventure for all ages that you will not soon forget: Aboard our semi-submarine, you will dive into the underwater world of the famous Caretta-Caretta sea turtles, photograph the beautiful Keri Caves and swim in their deep blue waters, sunbathe next to the turtles' nests at Marathonissi Island, and admire the picturesque little gulf of Cameo Island. And you will get to learn all about those sights, too, as all of our tours are accompanied by a detailed audio guide!
