The boat slips away from Agios Sostis and the island exhales salt and sun. A glass panel beneath the cabin floor reveals slow-moving shapes — loggerhead turtles drifting like slow moons beneath the surface — while the bow cuts toward the Keri cliffs. Waters here push and pull with the Ionian current; caves open like doors to startling blue chambers, and Marathonisi’s sandy rim offers a sheltered bay where sea turtles come to nest.

The boat slips away from Agios Sostis and the island exhales salt and sun. A glass panel beneath the cabin floor reveals slow-moving shapes — loggerhead turtles drifting like slow moons beneath the surface — while the bow cuts toward the Keri cliffs. Waters here push and pull with the Ionian current; caves open like doors to startling blue chambers, and Marathonisi’s sandy rim offers a sheltered bay where sea turtles come to nest.
Zakynthos sits on limestone carved by waves and wind; the south coast’s cliffs are compacted marine deposits that form sea caves and arches. The National Marine Park protects Caretta caretta and shoreline nesting sites established in the late 20th century, making this stretch one of Greece’s most important marine conservation areas. Local fishermen still bring ashore the day’s catch in small harbors; tavernas in nearby Laganas and Keri serve fresh grilled fish and simple island wines.
Practical guidance: tours run about three hours and combine viewing through the glass hull, a swim at the Keri caves, and a stop at Marathonisi for snorkeling and beach time. Expect brief stretches standing on deck, sun exposure, and salt spray. Bring reef-safe sunscreen, a lightweight wetsuit or rash guard if you plan to snorkel, and a waterproof camera. Maintain distance from turtles—approaching or touching is prohibited by park rules. Morning departures often mean calmer seas and clearer underwater visibility; late afternoon trips are quieter but can be windier. With straightforward logistics and a low physical requirement, this tour is ideal for travelers seeking wildlife viewing without long hikes.
Tours focus on areas where Caretta caretta are regularly sighted—visibility and sightings aren’t guaranteed but guides know the best spots and often find turtles, especially in calmer conditions.
Swim stops at Keri caves and Marathonisi are part of the itinerary; some operators rent snorkeling gear but bringing your own ensures fit and hygiene.
Yes—this tour is low‑impact and suitable for most ages; non‑swimmers should use a life vest and stay with the group on designated swim areas.
The National Marine Park requires visitors not to touch, chase, or feed turtles, to avoid littering, and to respect marked nesting areas—guides enforce these rules.
