About this experience
Cruise aboard Zakynthos' only glass-bottom yacht and discover some of the island's most beautiful coastal locations. Visit Marathonisi, swim in crystal-clear waters at the Keri Caves, admire the iconic Myzithres islets, and enjoy views of the underwater world through the yacht's glass-bottom viewing area. As you cruise through the Zakynthos National Marine Park, keep watch for Caretta-Caretta sea turtles in their natural habitat. While sightings are common during the season, they cannot be guaranteed. This relaxing cruise is ideal for families, couples and nature lovers looking to experience Zakynthos from the sea. Travel aboard the Royal Glass Bottom Yacht Athanasios V, the only vessel on this route equipped with an onboard sewage treatment system, helping to protect the marine environment while you explore it.

What you'll see and do
Marathonisi
Marathonisi — Turtle Island. The yacht heads to Marathonisi, the turtle-shaped island at the heart of the Zakynthos National Marine Park and one of the most important Caretta-Caretta nesting sites in the Mediterranean. As you approach, keep your eyes on the water through the glass bottom — turtles are frequently spotted feeding in these protected waters.
Pass by without stopping
Keri Caves
Keri Caves. The second stop takes you to the spectacular natural sea caves of the southern coast — dramatic limestone formations carved by the sea, with some of the clearest water on the island. Swim inside and around the cave entrance and photograph the extraordinary rock formations above.
Pass by without stopping
Myzithres. The cruise ends at the Myzithres — a cluster of small white rocky islets with electric-blue water that evoke the Caribbean, unique to Zakynthos. A final stop to take photos and soak in one of the most photogenic corners of the island before returning to port.

Why this scores 56
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Zakynthos Glass Bottom Yacht Cruise Turtles and Caves: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Zakynthos.
How much does Zakynthos Glass Bottom Yacht Cruise Turtles and Caves cost?
+
Prices start at $25 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 Zakynthos Glass Bottom Yacht Cruise Turtles and Caves take?
+
Plan for about 3 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 Zakynthos Glass Bottom Yacht Cruise Turtles and Caves worth it?
+
It holds an Outty Ranking of 56 out of 100, which we label "Worth a Look". That score blends traveler sentiment (0/5 across 0 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 Zakynthos Glass Bottom Yacht Cruise Turtles and Caves?
+
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 Zakynthos Glass Bottom Yacht Cruise Turtles and Caves suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 3-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Zakynthos Glass Bottom Yacht Cruise Turtles and Caves?
+
Around 0 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 3-hour experience runs outdoors or after sunset.
Where does Zakynthos Glass Bottom Yacht Cruise Turtles and Caves 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 Half-Day Greek Cooking Class of Zakynthian Culture with Lunch, Zakynthos Turtle Tour Small Group Turtle Spotting & Turtle Island, Zakynthos : One day small group tour to Navagio beach Blue Caves & top view. 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.
