The Itinerary in Detail

Stop 1: Marathonisi (Turtle Island)

This small, uninhabited island in Laganas Gulf is a sanctuary for Caretta Sea Turtles. Approaching by boat, you’ll appreciate the tranquility of this protected nature reserve, where the beaches are pristine and caves fascinating. Most travelers report the thrill of spotting a turtle in its natural habitat—truly a highlight for wildlife enthusiasts. The island’s large caves and crystal-clear waters make it a perfect first stop for swimming or just soaking in the scenery. As one reviewer put it, “We spotted turtles and swam at lots of different spots—it’s just stunning.”

Stop 2: Keri Caves and nearby spots

A few minutes’ cruise takes you to the Keri Caves, a series of natural formations that seem carved by the gods themselves. These caves offer dramatic landscapes and are ideal for swimming and exploring. According to reviews, the caves are a “primitive, time and space escape”, with a sense of untouched natural beauty. You can also swim at Eros Cave and Piscines Beach—the latter called the “Fallen Cliffs Beach” by some, famous for its still-incredible natural pools and quiet charm.

Stop 3: Mizithres

Next, you’ll visit Mizithres Beach, a newly formed paradise with unparalleled shades of blue along its sandy coasts. The Mizithres Rocks create a backdrop that many call the “new Shipwreck”—a dramatic, photogenic spot where you can swim around and enjoy the wild beauty. Travelers describe this as a “romantic break”, with some wishing they could stay forever. The rocks and beaches here offer a perfect mix of seclusion and stunning views.

Stop 4: Zakynthos Marine Park

No trip would be complete without a visit to the Marine Park, where sea turtles are protected and easily spotted in the crystal waters. This is a must-do for wildlife lovers, and the boat allows you to get close without disturbing the environment. The park is a sustainable way to see the turtles, and reviewers consistently mention how exciting it is to see them swimming freely.

Additional stop: Peluso Island (Kalonisi)

For a quick, hidden sandy shore, the boat can make a short visit to Peluso Island, an area inaccessible by land. It’s perfect for a quiet swim and offers a sense of discovery—many travelers describe it as a “hidden gem.”

Practical Details and What You’ll Love

All fees including fuel, taxes, and insurance are included, making it straightforward with no surprise costs.

What Past Travelers Say

One reviewer remarked, “Lilas, our captain, made us feel like royalty—very knowledgeable about the turtles and caves.” Others loved the flexibility of being able to stop and swim as we pleased and the beautiful views of the caves and beaches.

The only downside mentioned was the initial booking process—some guests found the directions via Viator a bit confusing, which underscores the importance of clear communication from the booking platform. The company’s response was quick and generous with refunds in cases of miscommunication.
