There are 4 types of Dolphins at the Corinthian gulf, one of them is very rare. Visit the Heraion archaeological site and swim at this ancient beach, full of relics of Ancient Greece. Afterwards, hop onboard and visit Alkyonides Islands where you will have the chance to meet the dolphins and play with them. After you meet and greet, you will enter the Heraion Lagoon through the narrow opening and dive into the crystal-clear water of the “blue lagoon”.
