About this experience

Loggerhead sea turtles have been residents of Zante's beaches for thousands of years, and with a bit of luck, you'll see them first-hand on this boat trip. Available either in the morning from Zante harbour or the afternoon from Keri harbour, this half-day cruise is a real treat for all the family. You'll pass by the golden beaches of Vassilikos and Marathonisi, a pine-clad islet dubbed ‘Turtle Island'. The reason's simple – one of its beaches is a favourite turtle nesting site. Plus, you'll sail along the Keri peninsula, cruising by its sea-plunging cliffs, caves and lighthouse before dropping anchor for a swim stop at the Bay of Oasis. In the small village of Keri, you have a quick stop to shop for souvenirs, relax in a typical taverna or hit the beach. What's more, a volunteer from local conservation group ARCHELON – the Sea Turtle Protection Society of Greece – will be on board to tell give you the lowdown on its work.

Turtle Cruise of Marathonisi Island and Keri Peninsula: questions travelers ask

Practical detail on this experience, plus the wider planning questions for Zakynthos.

How much does Turtle Cruise of Marathonisi Island and Keri Peninsula cost?

+

Prices start at $16 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Zakynthos usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

How long does Turtle Cruise of Marathonisi Island and Keri Peninsula take?

+

Plan for about 8 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Zakynthos is not rushed.

Is Turtle Cruise of Marathonisi Island and Keri Peninsula worth it?

+

It holds an Outty Ranking of 58 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.5/5 across 2 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Zakynthos, and how flexible the cancellation terms are.

Can I cancel or reschedule Turtle Cruise of Marathonisi Island and Keri Peninsula?

+

Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

Is Turtle Cruise of Marathonisi Island and Keri Peninsula suitable for kids and families?

+

Yes, all ages are welcome. Families should still weigh the 8-hour running time, and strollers are easier on the earlier, quieter departures.

How far in advance should I book Turtle Cruise of Marathonisi Island and Keri Peninsula?

+

Around 1 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Zakynthos can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

What should I bring or wear?

+

Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Zakynthos and add a light layer if any part of the 8-hour experience runs outdoors or after sunset.

Where does Turtle Cruise of Marathonisi Island and Keri Peninsula start and how do I get there?

+

The exact meeting point and directions are on your voucher once you book, and they sit in central Zakynthos within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

What are the best things to do in Zakynthos?

+

On Outty we rank every Zakynthos experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Exclusive Shipwreck & Blue caves Tour : Up to 10 guests, Kefalonia Wine Tour, Half-Day Greek Cooking Class of Zakynthian Culture with Lunch. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

When is the best time to visit Zakynthos?

+

Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

How many days do you need in Zakynthos?

+

Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

Do I book through Outty or through the operator?

+

Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
