Book with your eyes closed!!
Everything was perfect!! Thanks to our skipper, who was very attentive and organized things to share the most beautiful spots with us with maximum privacy! This company deserves to be known, located in a privileged place where there is 0 problem parking and with the feeling of being privileged.

A perfect afternoon
We decided to book a private boat tour (2 adults, 1 child (5yrs) to enjoy the blue caves and it was the best decision. The boat had the perfect size, they provided a child life vest for us and we were able to drive in the caves due to the size of the boat. It was a quiet and chill afternoon- whenever we wanted to stop and swim- we were able to. Unbelievably thankful for this experience. Thank you! Definitely a 10:10 experience and recommendation to do it with this boat company.

Amazing 5 star boat trip
Spiros was a star! We booked last minute, were late for departure time and were rather fractious (hungry and miserable). He was welcoming and patient and waited for us to have some food and regroup. We spent 3 incredible hours touring the magnificent southern coves and beaches , swimming and asking 100s of questions. The colour of the sea is hands down the most beautiful blue any of us have ever seen. We did not expect Spiros to extend our trip as we were late, but he voluntarily did so and we ended the trip in Laganas bay with a 🐢 turtle sighting (for the Mama who manifested; the non believers did not see it💪🏼). The boat was superb - deluxe seating and room for storage and we are super grateful for Spiros putting up with our music selections and occasional bickering. HIGHLY RECOMMEND!

Great trip with a professional captain
Great trip, Ianiss is a professional captain with precision handling! Well spoken in english. We did the 3h south trip to Keri Caves. Saw amazing places, stopped few times for 20 min swim. Highly recommend. After tgr tour, go for the lunch at the Porto Koukla Beach Hotel Taverna, right off then you get off the boat, great food and service!

Zakynthos: Private Cruise - Keri Caves, Myzithres & Marathonisi: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Zakynthos.
How much does Zakynthos: Private Cruise - Keri Caves, Myzithres & Marathonisi cost?
+
Prices start at $298 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: Private Cruise - Keri Caves, Myzithres & Marathonisi 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: Private Cruise - Keri Caves, Myzithres & Marathonisi worth it?
+
It holds an Outty Ranking of 55 out of 100, which we label "Worth a Look". That score blends traveler sentiment (5/5 across 8 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: Private Cruise - Keri Caves, Myzithres & Marathonisi?
+
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: Private Cruise - Keri Caves, Myzithres & Marathonisi 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: Private Cruise - Keri Caves, Myzithres & Marathonisi?
+
Around 3 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: Private Cruise - Keri Caves, Myzithres & Marathonisi 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 Ceramic Making Experience in Zakynthos, Half-Day Greek Cooking Class of Zakynthian Culture with Lunch, Zakynthos Turtle Tour Small Group Turtle Spotting & Turtle Island. 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.
What is included in Zakynthos: Private Cruise - Keri Caves, Myzithres & Marathonisi?
+
Included: Bottled water. Always check the voucher for the final list before you travel.
Where is the meeting point for Zakynthos: Private Cruise - Keri Caves, Myzithres & Marathonisi?
+
Located in Porto Koukla Beach Hotel Hotel pickup is not included, so plan your own transport and arrive 15 minutes early.
What languages is Zakynthos: Private Cruise - Keri Caves, Myzithres & Marathonisi offered in?
+
It runs in English. Pick your language when choosing a date and time, as not every departure runs in every language.
