If you visit Zakynthos Island you should definitely go to one of boat trips that include swimming stops in Marathonisi and Keri Caves.

​

We start the trip at the port of Agios Sostis and we navigate through the gulf of Laganas, a National Marine Park, to spot the amazing turtles, Carreta-Carreta. 

Our next stop is Marathonisi, also known as Zakynthos' Turtle Island, where we will stop at the caves to swim with the brightly colored fish. 

We will continue the journey and head to the Keri Caves, enjoying the beautiful south-west coastal scenery of Zante along the way. At the Keri Caves we drop anchor for another swim stop in the stunning crystal-blue waters.

​

The tour lasts 3 hours but additional hours can be added.
