Zakynthos: Turtle Spotting and Keri Caves Boat Tour

Zakynthos: Turtle Spotting and Keri Caves Boat Tour

Imagine setting out from Agios Sostis Port on a small, intimate boat with just a handful of fellow explorers—no crowded tours here. For around three hours, you’ll glide across the waters of Western Greece, visiting the Keri Caves, spotting Caretta Caretta turtles in their natural environment, and relaxing on Turtle Island or Marathonisi’s sunny shores. This tour promises plenty of photo ops, snorkelling, and the chance to see one of Greece’s most iconic marine creatures.

We loved the fact that this tour uses a small boat, which means you get up close—inside the caves—something bigger boats often can’t do. The crystal-clear waters and the chance to swim in the caves’ deep blue pools make it a true highlight. Also, the opportunity to observe sea turtles in their natural habitat feels like an authentic encounter rather than a staged spectacle.

One thing to consider is that the tour isn’t suitable for those prone to seasickness or with back problems, due to the small boat’s movement. Still, if you’re comfortable on the water, this activity is perfect for anyone eager to explore Zakynthos’s marine beauty in a more personal way.

This experience caters well to travelers who enjoy nature, adventure, and photography, especially those who appreciate a small group setting for a more relaxed and personalized experience. It’s ideal for families, couples, or solo travelers looking for a meaningful, eco-friendly day out.

Exploring the Zakynthos Turtle and Keri Caves Boat Tour

When planning a trip to Zakynthos, there’s no shortage of ways to enjoy its famed landscapes and marine life. This tour stands out because it combines adventure, nature, and small-group intimacy—a winning formula for those who want a more meaningful experience than just riding on a large boat with dozens of strangers.

Starting Point: Agios Sostis Port and Cameo Island

The tour kicks off at a cozy spot in front of a large villa with palm trees, a location that makes for a pleasant, easy meeting point. From here, the small boat sets out into the Zakynthos Marine Park, a protected area known for its pristine waters and diverse marine life.

The Treasure of the Keri Caves

One of the main draws of this trip are the Keri Caves, a series of dramatic sea caves and coves carved into limestone by the relentless waves over centuries. These caves are more accessible than you might expect, thanks to the small boat that can enter their depths—something larger vessels cannot do. Inside, you’ll witness spectacular sunlight reflections bouncing off the water, creating a kaleidoscope of blue hues.

For the more daring, there’s even a chance to swim through a small connecting tunnel between caves—an experience that adds a splash of adventure. If you prefer, you can simply relax on the boat and take photos of the stunning formations and the shimmering water.
