The afternoon light on Zakynthos slants gold across the Ionian; sea-slick cliffs pick out ridges while the boat’s hull cuts a steady line through Laganas Bay. From Agios Sostis Port you’ll board a comfortable glass-bottom vessel and let the water work its show—occasional pale shapes glide below, and the boat’s gentle motion sets a slow, marine rhythm to the day.

The afternoon light on Zakynthos slants gold across the Ionian; sea-slick cliffs pick out ridges while the boat’s hull cuts a steady line through Laganas Bay. From Agios Sostis Port you’ll board a comfortable glass-bottom vessel and let the water work its show—occasional pale shapes glide below, and the boat’s gentle motion sets a slow, marine rhythm to the day.
This stretch of coastline sits within the Zakynthos Marine Park, established to protect the nesting and feeding grounds of the loggerhead turtle (Caretta-caretta). Marathonisi—the small, turtle-shaped islet you’ll visit—was formed by geological uplift and sea action that left its sandy beaches ideal for basking and breeding. Nearby Keri Caves reveal limestone sculpted by waves; Myzithres, a pair of rugged sea stacks, frame a celebrated local sunset.
Expect an easy, family-friendly outing: guided turtle spotting over shallow bays, about an hour ashore at Marathonisi for swimming and beach time, a brief cavern swim at Keri Caves, then a sunset approach to Myzithres with a complimentary glass of wine. Guides point out natural history and local cultural notes as you travel.
Practical tips: bring reef-friendly sunscreen, a light wind layer for evening, and sturdy water shoes for rocky coves. Keep camera settings ready for low-light shots at dusk. Respect wildlife viewing rules—no chasing or touching turtles—and time your return transfer in accordance with local traffic and ferry schedules.
