Marathonisi is more than just a picture-perfect island—it’s a symbol of Zakynthos

Discover Marathonisi: The Turtle Island of Zakynthos

Nestled in the heart of Laganas Bay, just off the southern coast of Zakynthos, lies a small yet enchanting islet that captures the imagination of every traveler who sets eyes on it—Marathonisi, also known as Turtle Island. Shaped like a turtle floating in the turquoise Ionian Sea, this uninhabited island is one of Zakynthos’ most iconic and protected natural landmarks. Visible from many of the luxurious villas in the area, Marathonisi is more than just a beautiful sight—it's a symbol of the island’s rich biodiversity and a sanctuary for the endangered loggerhead sea turtle (Caretta caretta).

A Protected Paradise

Marathonisi is part of the Zakynthos Marine Park, a national park established to protect the unique marine ecosystem of the area. The island’s southern beach, made of soft white sand and gently sloping into crystal-clear waters, is an important nesting site for the loggerhead turtle. Each summer, these gentle giants return to the beach where they were born to lay their eggs, continuing a cycle of life that has lasted for centuries.

For this reason, access to the nesting beach is restricted during certain times of the year, and visitors are kindly asked to respect the conservation guidelines in place. It’s a rare and humbling experience to witness such natural wonder in progress—one that makes Marathonisi not just a tourist destination, but a living, breathing conservation story.

How to Get There

Reaching Marathonisi is easy and offers several options. From the popular beach resort of Laganas, you can rent a small boat, join an organized turtle-spotting cruise, or even take a kayak if you’re feeling adventurous. The ride to the islet takes no more than 15–20 minutes, and the journey itself is breathtaking, offering views of Zakynthos’ lush coastline, caves, and vibrant marine life.

As you approach the island, you’ll be greeted by two distinct beaches—one sandy, and the other pebbly and surrounded by dramatic limestone cliffs. Nearby, hidden sea caves provide excellent snorkeling and exploration opportunities for those eager to experience the underwater world.

A View from the Villas

For those staying in villas perched above the coastline, Marathonisi can be admired from afar—especially during sunrise or sunset, when the light hits the water and the island takes on a magical glow. Many luxury accommodations offer private balconies or infinity pools with unobstructed views of the bay and the islet, allowing guests to enjoy its beauty in peace and comfort.

Waking up to the sight of Marathonisi each morning is a memory in itself—a constant reminder of the island’s untouched charm and the deep connection between nature and serenity that defines Zakynthos.

What to Bring & What to Know

When planning a visit to Marathonisi, remember to bring eco-friendly sunscreen, drinking water, and a hat, as there are no facilities on the island. Due to its protected status, visitors are asked not to bring umbrellas or dig in the sand, as turtle nests may be hidden just below the surface.

There are also floating snack boats that visit the island seasonally, offering drinks and light refreshments for visitors. However, most people come not for the snacks but for the serenity, the wildlife, and the chance to feel immersed in an untouched Mediterranean paradise.

Final Thoughts

Marathonisi is more than just a picture-perfect island—it’s a symbol of Zakynthos’ commitment to preserving its natural heritage. Whether viewed from the comfort of your villa or explored up close by boat, the islet invites you to slow down, connect with nature, and experience the magic of the Ionian Sea. For nature lovers, couples, and families alike, a visit to Marathonisi is an unforgettable highlight of any Zakynthos getaway.
