South Zakynthos Boat Trips — From Agios Sostis

The south coast of Zakynthos is the calm side — sheltered turquoise waters, hidden caves carved into limestone cliffs, and the National Marine Park, home of the loggerhead sea turtle. Our south-coast excursions all depart from Agios Sostis harbour and combine swimming stops, wildlife encounters and some of the most photogenic seascapes in Greece.

Why Choose South Zakynthos?

  • Calm, sheltered waters — ideal for families and first-time sailors
  • Sea turtle sightings most days during summer
  • Keri Caves, Mizithres Rocks, Marathonisi (Turtle Island)
  • Marathia thermal sulphur springs
  • Eros Cave — accessible only by small boat
  • Multiple daily departures, no upfront payment
