Marathonisi — Turtle Island. The yacht heads to Marathonisi, the turtle-shaped island at the heart of the Zakynthos National Marine Park and one of the most important Caretta-Caretta nesting sites in the Mediterranean. As you approach, keep your eyes on the water through the glass bottom — turtles are frequently spotted feeding in these protected waters.

Keri Caves. The second stop takes you to the spectacular natural sea caves of the southern coast — dramatic limestone formations carved by the sea, with some of the clearest water on the island. Swim inside and around the cave entrance and photograph the extraordinary rock formations above.

Myzithres. The cruise ends at the Myzithres — a cluster of small white rocky islets with electric-blue water that evoke the Caribbean, unique to Zakynthos. A final stop to take photos and soak in one of the most photogenic corners of the island before returning to port.
