While we haven’t personally boarded this specific tour, the detailed reviews and itinerary paint a picture of a well-organized, memorable journey. It’s perfect for those who love the water, wildlife, and scenic coastlines.
What really stands out about this tour is the personalized touch and knowledgeable guides. We love that Angelo, the skipper, isn’t just about navigation — he’s also eager to share insights about the caves, the marine park, and the turtles. One potential consideration is the 3-hour duration, which might feel quick for travelers eager to explore every nook of the area. But for those who value a focused, high-quality experience, this tour hits the right notes.
This trip is ideal for adventurers, wildlife lovers, and those seeking a more intimate, guided experience. If you’re traveling with family, friends, or as a couple looking for a private escape, this tour offers excellent value and an immersive way to discover Zakynthos’ coastal treasures.

More ways to experience Agios Sostis from the water include these boat tours

The tour begins at the charming Agios Sostis harbor, where you’ll meet your skipper and hop aboard the boat, often a modern vessel like Nikoleta. Reviews mention Angelo as the captain, who is regarded as highly experienced, friendly, and informative. This initial meeting sets a relaxed tone, emphasizing safety and comfort from the start.
Your journey kicks off with a cruise into the National Marine Park of Zakynthos, a protected area known for its unique marine life, especially the endangered Caretta Caretta turtles. Travelers have praised the guides’ dedication to conservation, following strict rules to safeguard these creatures. Expect to spend about 45 minutes here on your first stop, with opportunities to see turtles surfacing, and even capture that iconic moment when they raise their heads from the water.
One reviewer, Anthony, shared, “Anna and Angelo made sure we were safe and comfortable out on the water. We saw turtles, which was a highlight — the water is so clear and different shades of blue.” This highlights how clear, shallow waters provide better sightlines, making turtle spotting more rewarding.
Next, your boat heads to Turtle Island (Marathonisi)—a small, protected islet that resembles a turtle, hence the name. Locals love it for stories of pirates and its scenic beaches. The island has two main beaches: one with pebbles, the other with fine white sand. While the schedule limits your time here, the reviews confirm that the visit is well-managed, with strict adherence to park rules about how long you can stay, ensuring the environment remains pristine.
Melissa’s review emphasizes the experience: “We did see turtles, and the water’s so clear. The trip was memorable — a perfect balance of fun and respect for nature.” Keep in mind, this stop is designed to be a snapshot rather than a lengthy stay, so if you’re hoping for a lazy beach day, you’ll need to plan accordingly.
The third highlight is the Keri Caves, located on the southwestern coast. These caves offer excellent snorkeling opportunities in turquoise, crystal-clear waters. Explorers will love the chance to see the natural formations and explore caves filled with interesting rock features and arches. The reviews praise Angelo’s navigation skills and his ability to bring visitors close enough to caves for memorable photo moments.
The caves are described as a must-visit for snorkeling lovers, with many reviewers noting the vivid colors of the water and the natural beauty of the caves. With about 2 hours allocated, this stop balances exploration with safety, and the snorkeling gear provided makes it accessible—even for beginners.
The final stop is the Mizithres Rocks, towering white formations emerging from the sea, shaped like chunks of cheese (hence the name). These imposing rocks are part of a larger cluster of caves and arches, forming a signature part of Zakynthos’ coastline. Reviewers highlight the spectacular photo ops here, as the rocks provide a dramatic backdrop for the last leg of your trip.
This area offers a chance to relax, soak in the views, and reflect on the day’s highlights. The experience of seeing these grandeur formations up close is often described as breathtaking, with many travelers noting that these views are some of the most stunning on the island.

While many boat trips offer similar stops, this particular tour shines in its personalized approach. Keeping the group small, with a private setting, means Angelo and the team can tailor the experience, answer questions, and ensure safety. The inclusion of snorkeling gear, refreshments, and strict adherence to environmental guidelines makes it a responsible choice.
Reviewers repeatedly mention the knowledgeable guides who go beyond navigation, sharing stories and insights, which makes the experience richer and more engaging. For instance, one traveler noted how Angelo “pointed out places we never would have found on our own,” adding a layer of discovery to the adventure.
At $316 for a private group, this tour might seem a bit steep for some. However, considering it’s a private experience with expert guidance, all equipment included, and multiple stops, many find the value to be justified. It’s a more intimate alternative to larger group excursions, and the reviews consistently praise the quality of the experience, especially the safety, comfort, and authenticity.
The tour lasts around 3 hours, with availability depending on the day. Meeting at Agios Sostis harbor, you’ll find the boat waiting at a designated spot near a small chapel. The tour operates with flexible cancellation policies (up to 24 hours in advance for a full refund), making it easier to plan. The activity is conducted in English, and the group is private, which means fewer strangers and more personalized interaction.
Travelers should bring essentials such as sunglasses, sun hats, swimwear, towels, sandals, sunscreen, and beachwear. Note that alcohol and drugs are not allowed, emphasizing safety and respect for wildlife.
This trip is perfect for families, couples, or small groups who appreciate a well-organized, eco-conscious adventure. It’s suitable for travelers eager to see marine life and enjoy scenic coastlines without the crowds. It’s especially good for those who want a more intimate, guided experience rather than a large, impersonal cruise.
However, it’s not recommended for individuals with mobility issues due to the nature of boat boarding and water access. Also, since the tour is weather-dependent, flexible planning is advisable.

This guided boat tour in Zakynthos offers a balanced mix of wildlife viewing, scenic beauty, and expert guidance. The chance to spot a Caretta Caretta turtle in its natural habitat, combined with visits to Turtle Island, Keri Caves, and Mizithres Rocks, makes it an all-encompassing coastal adventure. The focus on environmental responsibility and personalized service ensures you’re not just another tourist, but a respectful visitor with a chance to truly connect with Zakynthos’ natural charm.
If you’re after a straightforward, well-reviewed, and memorable boat trip that blends fun and wildlife conservation, this tour is a wise pick. It delivers high-quality moments for a reasonable price, especially if the idea of a private, guided experience appeals to you.
