Details
Embark on our boat trip to Marathonisi Island and Keri Caves, and immerse yourself in an unforgettable turtle-filled journey. Experience the breathtaking beauty of Greek caves, swim along the picturesque coast of the turtle island, and, above all, take the opportunity to spot turtles in the bay of Laganas.
Our journey will start in the port of Agios Sostis from where we will depart south-west to the popular Keri Caves. Here we will stay for around 20 minutes so that you can enjoy a swim in the crystal clear turquoise waters of the cave complex. The next stop is the Marathonisi Island. The turtle shaped island is actually also the Caretta-Caretta's turtle main nesting spot on Zakynthos and on top of all you can enjoy its beautiful sandy beaches. We will stay here for about 50 minutes.
Then we will navigate through the bay of Laganas for 1 hour, where you can spot for Caretta-Caretta turtles. Unless weather conditions do not allow it, you will for sure see some of these wonderful creatures in this time span. After you have filled your camera with some great holiday pictures throughout this 3-hour trip, we will return to the port of Agios Sostis. Highlights

Wonderful trip and very well organized. We saw everything that was promised, and the guide explained it all in a very interesting way. The skipper was excellent and clearly very experienced. Highly recommended!

Amazing experience

The caves were amazing, jumping from the boat for a swim was amazing. The turtle island stop was ok, not perfect overcrowded with people, not much room to sit but overall experience was good. Thanks
