An Overview of the Tour Experience

The journey begins with a convenient pickup from your resort or designated meeting point, often in a mini bus marked Happy Days Zante. This makes logistics simple and ensures you’re ready to set out without fuss. Once at the port of Agios Sostis, you’ll board a specialized glass-bottom boat—a sleek vessel designed to offer clear views beneath the surface while cruising comfortably on top.

The first major stop is Marathonisi, popularly known as Turtle Island. Its distinct turtle-shaped silhouette, featured prominently in many photos, serves as a nesting site for loggerhead turtles. Here, you’ll see white sandy beaches and rocky surroundings that form a perfect backdrop for wildlife observation. As the boat circles the island, the captain (also the guide) might point out signs of nesting or feeding activity.

While the primary goal is turtle spotting, the tour also explores one of the area’s impressive caves. The boat’s glass bottom offers a peek at underwater formations or marine life that you might not notice from the deck. Some reviews note that the views of the coastline and caves are truly picturesque, making it an excellent opportunity for photography, especially for those keen on capturing the rugged beauty of Zakynthos’ coast.

Next, you’ll have time to swim and snorkel in the crystalline waters. Although the tour does not include snorkeling equipment, many travelers take the chance to cool off and marvel at the vibrant fish and underwater rock formations. If you prefer staying dry, the glass bottom provides ongoing entertainment, revealing marine creatures and the fascinating underwater landscape.

Throughout the tour, the guide/captain shares insights about the local environment, turtle conservation efforts, and the geological features of the caves—adding depth to the experience. Bottled water is provided, but it’s handy to bring your own snacks or extra drinks if desired.

What Makes This Tour Stand Out

The main draw is the chance to see Caretta Caretta turtles in their natural habitat. Many reviews mention how special it is to watch these gentle creatures glide through the water. One visitor remarked, “We loved the way we saw a turtle surface right next to the boat—it was magical.” This close-up wildlife experience is often cited as the highlight.

The scenic coastline and caves are equally compelling. The boat’s design allows for unobstructed views, and many travelers find themselves taking dozens of photos of the rugged cliffs and hidden caves. The natural beauty of Zakynthos’ coastline, combined with the marine life, offers a well-rounded picture of what makes this part of Greece so special.

The value for the price is generally praised. Considering the included pickup, boat ride, guide, and bottled water, the tour is a straightforward, cost-effective way to explore. However, since food and other drinks are not included, bringing your own snacks might be wise if you plan to extend your day afterward.

In-Depth Itinerary Breakdown

Pickup and Transfer: The tour starts with a pickup from your hotel or a nearby location, usually a few minutes before the scheduled time. The mini bus, identifiable as Happy Days Zante, transports you to Agios Sostis port, ensuring a smooth transition from land to sea.

Boat Ride to Turtle Island: Once aboard, the captain takes the wheel, and the cruise begins. The boat’s glass bottom allows everyone to observe beneath the waves, whether they’re seated on the deck or inside the covered area. The ride is approximately an hour each way, during which the guide points out features like the coastline, caves, and perhaps even dolphins if luck is on your side.

Turtle Watching at Marathonisi: The first stop is Turtle Island itself, a small but scenic island with pristine beaches. The guides often explain turtle nesting habits and conservation efforts, making this part both educational and awe-inspiring. Many reviewers have shared that they loved seeing the turtles surface or swimming near the boat—truly a highlight.

Exploring Caves & Swimming: The boat ventures into nearby caves, with some allowing you to peek through openings or enjoy the view from the boat itself. For those eager to get wet, swimming in the clear waters is an option—perfect for cooling off after the boat ride.

Authentic Encounters and Practical Tips

From reviews, it’s clear that the guide’s insights about turtles and caves add a lot of value. They’re friendly, knowledgeable, and eager to answer questions, making the experience feel personal and engaging.

Travelers often mention bringing essentials like sunglasses, hats, sunscreen, and a camera—the Greek sun can be strong, especially during summer. Swimwear and towels are recommended if you plan to swim, while waterproof cases for phones help protect your gear.

While the tour is designed for convenience, it’s important to note that food and drinks are not included. Packing a small snack could enhance your comfort, especially if you’re prone to hunger during boat rides.

The group size tends to be manageable, with reviews indicating a friendly, non-overcrowded atmosphere. The length of the trip suits those who want a quick but rundown of Zakynthos’ marine environment without committing to a full-day tour.
