Lowest Price Guarantee
Enjoy a small boat trip to the caves of Keri, Mizithres, and Marathonisi and see the beautiful turtles swimming next to the boats on the amazing beaches of Zakynthos. After you have been picked up from your accommodation or the closest meeting point by our air-conditioned bus, you will set off from the port of Agios Sostis. Let a cool breeze waft across your face on a three-hour boat trip. Take home impressive memories as you discover the Keri Caves and Marathonissi. Do not fail to refresh yourself in the Ionian Sea. Bath and snorkel before making your way back to the port of Agios Sostis. Keep an eye out for the well-known Caretta-Caretta turtle, which, with some luck, will accompany you on the crossing. Your well-deserved lunch with local dishes awaits you in a traditional tavern near the harbor.

Everything was perfect on this tour, have many experience, like swimming in the see, spotting turtles and have fast travel on a motorboat around Zakynthos. We really loved it. Thank you 😊

I’ve done Mizithres tour and it was amazing. The captain has done a great job showing us all the beautiful places, and the turtle!

Our boat excursion to Marathonisi was absolutely magical! Known as Turtle Island, this paradise exceeded all our expectations. The boat ride was relaxing and offered incredible views of Zakynthos' coastline and turquoise waters.
