Zakynthos: Turtle Spotting, Marathonísi & Keri Caves Cruise

Taking a cruise around Zakynthos often means chasing the legendary Navagio Beach, but for a more intimate and nature-focused experience, the Zakynthos Turtle Spotting, Marathonísi & Keri Caves Cruise offers a compelling alternative. This tour, lasting roughly 3.5 hours, is designed to showcase some of the island’s most captivating natural sights while giving travelers a chance to see the Caretta caretta turtles in their habitat.

What we really appreciate about this cruise is its eco-friendly approach—using a glass-bottom vessel that minimizes impact on the environment while maximizing views. Plus, the chance to swim at Marathonísi Island, known as “Turtle Island,” and explore the spectacular Keri Caves promises a well-rounded, nature-centric adventure.

A potential consideration is that, being a shorter tour, it might feel a bit rushed for those wanting a more in-depth exploration of each site. Also, since food and drinks are not included, packing some snacks is a good idea, especially if you plan to spend more time swimming or relaxing.

This experience suits travelers who love wildlife encounters, appreciate authentic natural beauty, and prefer a smaller, more personal boat trip over the crowded big-group excursions. It’s perfect for families, couples, or solo travelers eager for a taste of Zakynthos’ stunning coastal environment without the fuss of longer tours.

A Closer Look at the Experience

Starting Point and Logistics

The cruise departs from Ag Sostis port, near the Cameo Bridge, marked by big yellow flags and a distinctive yellow glass-bottom boat with the Zante Sun Travel logo. The timing varies, but most departures are around midday, giving you a good window to fit into your day’s plans. Arriving 20 minutes early guarantees a smooth start, and the process is straightforward with hotel pickup from several key locations like Laganas, Kalamaki, and Argasi.

The transportation is included, which is a nice touch—no need to worry about organizing taxis or parking. The trip itself lasts around 3.5 hours, which feels just right for a relaxed yet fulfilling adventure.

The Boat and Crew

The vessel is described as spacious and safe, and while some reviews mention it’s smaller than other boats, this actually turns out to be an advantage. Smaller groups, often around 12-15 people, allow for a more intimate experience and more opportunities for turtle sightings and swimming.

The crew, especially noted for their helpfulness and knowledge, enhances the trip. One review mentions Captain Dennis doing a “great job,” and another highlights “a father-son duo” who add a personal touch. Expect friendly, approachable guides who are eager to point out wildlife and share tidbits about the island’s geology and ecology.

Turtle Spotting – A Rare Encounter

The highlight for most travelers is the chance to see loggerhead turtles in the wild. We loved the way guides keep a watchful eye on the water, helping guests spot these gentle creatures. According to reviews, it’s a “rare and humbling sight” that leaves a lasting impression. One visitor said, “It was really nice experience with the possibility to spot turtles and swim with fishes,” illustrating how genuine the wildlife encounters can be.

Keep in mind, however, that sightings are not guaranteed. Some reviews note seeing just a couple of turtles, which shows nature’s unpredictability—but even a glimpse can be memorable.

Marathonísi Island: Turtle Paradise

After turtle spotting, the boat heads to Marathonísi Island, affectionately called “Turtle Island” because of its shape and importance as a nesting site. Here, you can swim in the clear turquoise waters or relax on the Golden Beach, which remains largely untouched and serene.

Reviewers often mention the beauty of the swim stops—one described jumping directly into the “super blue clear waters” from the boat. The island’s natural beauty offers a peaceful break from the boat ride, and the small time allocated means you need to be efficient with your swimming and exploring.

Keri Caves: A Hidden Gem

The tour’s final stop is at the Keri Caves, a true highlight for lovers of dramatic coastline scenery. These caves, carved into the rocks over centuries, can be explored directly from the boat. Many guests enjoy swimming through the caves or simply marveling at the breathtaking rock formations and the play of sunlight on the water.

One reviewer remarked they were able to enter the caves with the boat, which added a unique perspective. The caves’ reflections dancing on the waves make for some stunning photos and memorable moments.

Returning and Overall Value

The cruise concludes back at Laganas Bay around 3 or 6 pm, depending on the tour time booked. Reviewers consistently mention how the price feels reasonable considering the quality of the experience, especially given the small group size, wildlife sightings, and beautiful stops.

While food and drinks are not included, the overall value stems from the authentic nature experience and the personalized feel of the tour. It’s a cost-effective way to see some of Zakynthos’ natural wonders without the crowds or higher prices of longer, more commercial excursions.

Who Will Love This Tour?
