Zakynthos: Turtle Island & Keri Caves Glass-Bottom Boat Tour

A boat trip that promises encounters with loggerhead turtles on Turtle Island and the chance to explore the famous Keri Caves is hard to resist when visiting Zakynthos. These tours, offered by Happy Days Zante, attract travelers eager for a mix of wildlife sightings, scenic beauty, and a bit of adventure—all from the comfort of a glass-bottom boat. The tour lasts between 3 to 5 hours, depending on your chosen options, and offers a chance to see some of Greece’s most stunning coastline.

What I really like about this experience is how friendly and knowledgeable the guides are—particularly Captain Dennis, who gets rave reviews for his humor and expertise. I also appreciate how accessible the tour is, with options that include hotel transfers from popular spots like Kalamaki and Zante Town. However, it’s worth noting that this is a weather-dependent trip; if seas are too choppy, tours could be canceled or rescheduled. Still, for a reasonable price of just over $28, this outing provides a lot of value for wildlife lovers and scenery seekers alike.

One potential drawback is that swimming at some stops can be limited if the weather isn’t ideal—something that many reviewers have mentioned. Still, even with that, the chance to see turtles in their natural environment makes this a memorable outing. Plus, the photos and stories of encounters with Dennis or other guides add a personal touch that many travelers find charming and authentic.

Key points / Takeaways

• Wildlife Encounters: Chances to see loggerhead turtles early in the trip, often almost immediately after boarding.

When I look at a tour like this, I see it as a great way to combine natural beauty with wildlife watching—all without needing a diving license or a snorkel obsession. That said, this trip is very much about the experience of being on the water, the thrill of spotting a turtle, and enjoying the rugged coastline. It’s a good fit if you’re traveling on a budget but want a full, scenic day with some wildlife excitement thrown in.

How the Tour Is Organized

The tour starts from either a designated meeting point at Agios Sostis Harbor or, if you prefer, with hotel pickup from popular locations such as Kalamaki, Alykanas, Tsilivi, or Zante Town. The main activity is a glass-bottom boat ride, which allows you to peer into the water and catch glimpses of marine life without getting wet. This can be especially helpful if you’re traveling with young children or prefer a more relaxed experience.

The route takes you across crystal-clear waters to several key spots: Marathonisi Island (also called Turtle Island), the Keri Caves, and other scenic coves. The highlight for most travelers is the chance to see loggerhead turtles—the tour’s namesake—often right from the boat or on the nearby nesting beaches. According to reviews, Captain Dennis and his crew seem especially adept at finding turtles and making the experience engaging.

What to Expect at Each Stop

Marathonisi Island is shaped like a turtle, which makes it a perfect habitat for the caretta caretta turtles. Many travelers (including those in reviews) mention seeing turtles almost immediately after boarding, which makes for a memorable start. The island has a nesting beach, and if you’re lucky, you might spot a turtle in the water or resting on the sand.

The Keri Caves are a favorite for their impressive arch formations and turquoise waters. Reviews highlight how the light plays beautifully on the caves’ walls. You’ll have time to swim, snorkel, or simply take photos from the boat. Bringing your own snorkeling gear is recommended if you want to explore beneath the surface.

Later stops often include a scenic beach or cove where you’ll have some free time—usually around 50 minutes—to relax, take pictures, or swim. The tour sometimes visits Cameo Island or other charming spots, giving you a chance to stretch your legs and enjoy the spectacular surroundings.

The Role of the Guides

The reviews consistently praise Captain Dennis for being funny, friendly, and incredibly knowledgeable. He shares interesting tidbits about sea turtles and local history, making the trip more than just a boat ride. Several reviewers mention how Dennis’s sense of humor and attentiveness made the experience stand out, especially with children who were entertained and even got to “steer” the boat.

Practical Details and Logistics

The tour lasts between 3 and 5 hours, depending on the route and weather conditions. It includes liability insurance for peace of mind and a guide/captain to ensure safety and fun. If you select the transfer option, expect pickup from your hotel with a small, friendly bus—making logistics smooth and straightforward.

At a price point of just over $28 per person, this tour offers excellent value, especially considering the multiple stops, the chance to see wild turtles, and the scenic beauty. The price also covers insurance and a professional guide, which are worth noting as part of the value.

Who Is This Tour For?

This experience is ideal for families, couples, or solo travelers who want a relaxed day on the water with wildlife viewing and scenic landscapes. It’s also suitable for those on a budget, as it delivers a lot for the price. However, if you’re looking for an intense or lengthy adventure, the 3- to 5-hour window may feel limited. Also, if you have mobility issues or are wheelchair users, this might not be suitable due to certain logistic constraints.
