Itinerary

60 min

Enchanting Island of Marathonisi islet Stop for Swimming at beautiful Sandy Beach. Marathonissi is a small private island in the turtles’ bay close to Limni Kerì’s beach. Until the second world war the island was lived, today it has neither inhabitants nor buildings. It is now one of the areas where the CARETTA CARETTA turtles go to breed.

40 min

First Stop will be at Keri Caves - Amazing place First Stop for Swimming Kerì Caves, accessible only by sea with private boats or our excursions, develop along the promontory of Marathia Cape, in the South-West area of the island. Along the coast there are many caves which entrances scarcely suffice to get in swimming, others are broad enough to enter directly with a boat. It is very easy to reach the caves that are surmounted by cliffs where the sea is very deep and as such reachable.

45 min

Turtle Spotting: Starting with Turtles Spotting just out in the Laganas Bay The Caretta Caretta Turtle is a specimen still living in the Mediterranean and it is possible to meet it there since it spawns along the beaches of the Laganas Gulf. They can have considerable dimensions (the largest weights 140 kg. and measures circa 120 cm whereas the smallest measures 80 cm.) but, in spite of this, they are very fast. Thanks to the big anterior and the stiff posterior fins they can reach 30km/hour and so protect themselves from possible dangers.

😁A+ Must do experience

We had a fantastic time on this excursion. The boat trip was well organised, amazing scenery around with crystal-clear water. Seeing the turtles in their natural habitat was the highlight of the trip, and visiting Marathonissi Island was a wonderful experience. There are places to grab a cocktail and ice cream on the island visit. The staff were amazing, friendly, professional and very efficient throughout the whole trip. They made everyone feel welcome and ensured everything ran smoothly from start to finish. One tip for future visitors: if you plan on swimming from the boat to the island and are not a confident swimmer, or you have children with you, it is worth bringing your own life jackets, armbands or floatation aids to make the experience more enjoyable and comfortable. Overall, this was an excellent excursion and great value for money. If you are visiting Zante, I would highly recommend this trip. ⭐⭐⭐⭐⭐ 5/5

A great adventure near Keri

We really enjoyed this excursion! We saw turtles and swam in some of the most beautiful places we have ever seen. There are lots of caves along the way too. Bring your snorkel and mask if you have one, it was super clear and beautiful in the water at the first swimming stop. Highly recommend!

A boat tour not to be missed.

A very beautiful tour, with wonderful places. Fabio was very helpful from the booking to the conclusion of the tour. Sergio was also excellent in showing us the various characteristic views at each stop.
