This archipelago, or chain of islands, includes seven main islands as well as a number of smaller islands. They are actually referred to in Greece as the “Heptanese” which literally translates to “seven islands”. These seven main islands are Lefkada or Lefkas, Meganisi, Kefalonia, Ithaca, Kastos, Atokos, and Zakynthos or Zante. The diving here is beautiful and the islands are also known for their stunning beaches, clear waters, and picturesque scenery. Each one is quite unique in its own regard and offers its own special experience. The Ionian Sea waters have plenty of marine life, caves reefs, large rocks, and more. The water here is both very deep and very clear. Visibility can be over 30 meters (98 feet) and the seafloor can be as deep as 4,000 meters (13,000 feet). The underwater world features everything from large rocks and caves to beautiful Mediterranean reefs, not to mention the mainly World War Two wrecks, such as the amazing HMS Regulus off the coast of Corfu and the submarine HMS Perseus off the coats of Kefalonia which is now a vibrant artificial reef. Try some of the smaller island for an authentic Greek welcome, too.
