The boat slips away from Laganas as the coastline thins into cliffs and low scrub. Salt slicks the air, and crews chat softly while the glass-bottom hull slides over clear water that sometimes reveals a shadowed fin or the pale curve of a sea turtle’s shell. As the sun leans west, the Mizithres rocks grow into silhouettes—rugged pillars where light and sea argue for attention.

The boat slips away from Laganas as the coastline thins into cliffs and low scrub. Salt slicks the air, and crews chat softly while the glass-bottom hull slides over clear water that sometimes reveals a shadowed fin or the pale curve of a sea turtle’s shell. As the sun leans west, the Mizithres rocks grow into silhouettes—rugged pillars where light and sea argue for attention.
This stretch of Zakynthos has a recent geological story: uplifted limestone carved by waves into caves, arches and the small islets called Mizithres. Marathonisi ("Turtle Island") is a natural nursery—sandy bays and dunes that serve Caretta caretta nesting cycles that modern tourism now tries to respect. Keri’s caves show the island’s marine sculpting; the light inside them takes on an almost electric blue when sun angles are right.
Expect a leisurely cruise with swim stops at Marathonisi, guided passages along the Keri Caves and an anchoring for sunset at Mizithres. The glass-bottom section offers quick glimpses beneath the boat; snorkeling is often allowed at calm coves. Crews typically provide light drinks and music, and the pace is relaxed—designed for photos, swims and wildlife watching rather than intense exploration.
Practical notes: bring reef-safe sunscreen, a towel, and a light wind layer for the return as temperatures fall with the sun. If you’re prone to seasickness, take precautions before boarding. Boarding is straightforward from Laganas; tours run most of the warm season but check weather cancellations—southerly meltemi winds can put caves and small islets off-limits.
The tour runs approximately 3–4 hours depending on sea conditions and the time spent at swim stops and sunset viewing.
Caretta caretta are frequently seen in Laganas Bay but sightings cannot be guaranteed; sightings depend on season and sea conditions.
Some operators provide basic snorkeling gear; check the tour details or bring your own for a better fit and hygiene.
Yes—this is family-friendly, but infants should sit on laps and children should be supervised during swim stops and while boarding.
