If you’re dreaming of exploring Zakynthos from the water, a Turtle Spotting Cruise on a glass-bottom vessel might just be the experience you’re after. We haven’t done it ourselves, but after checking out the details and reviews, it’s clear this tour offers a memorable way to enjoy some of the island’s most iconic sights.

Starting Point and Duration
The tour kicks off from Laganas Beach in the morning, with a departure time that’s easy to plan around. Lasting roughly 3 hours, it’s a manageable chunk of time for most travelers—long enough to soak in the sights but not so lengthy that it eats up your entire day. The fact that tickets are booked on mobile makes it simple to secure your spot ahead of time, especially since most travelers book about 25 days in advance.
The Itinerary Breakdown
Stop 1: Laganas Beach – The Departure
The cruise sets off from the Gulf of Laganas, a pretty popular starting point. Your guide will share some details about Caretta-caretta turtles, helping you understand why this species is so crucial and endangered. The crew will actively look for turtles surfacing for air — a highlight for many. Knowing that you’re part of a responsible eco-friendly tour adds a layer of peace of mind, especially if you’re passionate about marine conservation.
One reviewer, Dorthe, shared, “Great trip with Dennis,” praising the captain’s enthusiasm and expert navigation in the caves. This hints that the crew’s knowledge and attitude can genuinely enhance your trip.
Stop 2: Marathonisi, or Turtle Island
This island, shaped like a turtle, is uninhabited and protected as a nesting site for sea turtles. Here, you’ll likely enjoy swimming and snorkeling in crystal-clear waters—a perfect chance to cool off and take some photos. The golden beaches are ideal for relaxing, especially if you’re into beachcombing or just soaking up the sun.
One guest, Faye, noted that she appreciated the friendly and informative staff, and loved seeing the turtles and caves. She also mentioned the trip was a bit choppy but ultimately fun. This suggests that even with some water roughness, the experience remains enjoyable if you’re comfortable on a boat.
Stop 3: Keri Caves
The Keri Caves are a highlight for many. Accessible only by boat, these caves showcase incredible rock formations and natural beauty. You might find swimming or snorkeling inside the caves quite magical—light bouncing off white stone walls reflecting onto the water creates a truly scenic view.
A reviewer, Karin, said, “Gelukkig schildpadden kunnen zien en super sfeer op de boot,” meaning she was happy to see the turtles and enjoyed the great vibe on the boat. Expect to spend a little time exploring and soaking in the peaceful environment, making this stop a perfect balance of adventure and relaxation.
What to Expect on the Boat
The vessel is glass-bottomed, allowing you to observe marine life without getting wet—something many travelers appreciate. The boat’s size can be as large as 45 travelers, so it’s not overly crowded, but expect some fellow travelers sharing the experience. The trip is described as eco-friendly, which aligns well with conservation-minded travelers.
The Realities of the Experience
While many reviews praise the opportunity to see turtles and the stunning caves, there are a few considerations. The water can be choppy, which might not suit everyone. Also, some travelers have noted that meeting points can be confusing or not clearly marked. For example, one guest waited at the Zante Sun flags, but the boat departed from a different location, which could cause some stress if you’re not paying close attention.
