Zakynthos: Turtle Spotting and Keri Caves Boat Tour｜Greece

Set sail on a small boat to explore the Keri Caves and Turtle Island on a tour from Agios Sostis Port. Swim in the crystal-clear waters of the Keri Caves, and see the island that is shaped like a giant mother turtle.

Meet your captain at the port and set sail to the Keri Caves. Observe the turtles in their natural habitat and take as many pictures as you like. Explore the large caves and coves of Keri, where you'll stop for a swim in the crystal-clear blue waters. One advantage of using a small boat is that you can actually enter the caves—something larger boats can't do. Inside, witness spectacular sunlight reflections off the deep waters, turning them bright blue.

If you're feeling adventurous, you can even swim through a small connecting tunnel between the caves. After exploring the Keri Caves, set sail to Marathonisi, more commonly known as 'Turtle Island.' Not only is this a key nesting beach for sea turtles, but the island is also shaped like a giant mother turtle.

Sail around Turtle Island and stop on its beautiful northern beach for sunbathing, swimming, and maybe even a treat from one of the floating bars offering cold drinks and ice cream. After an exciting day of exploring Zakynthos Marine Park, return to Agios Sostis Port with unforgettable memories shared among your fellow adventurers and your experienced captain.
