Marathonisi & Keri Caves Tour

Tour Information

Join us on a scenic cruise along the southern coast of Zakynthos, starting from Tsilivi Port. Our first destination is the magical Keri Caves, where you can swim in striking blue-green waters and explore the unique underwater landscape. You’re welcome to stay as long as you'd like at this stunning natural spot.

Next, we head to the beautiful islet of Marathonisi — also known as Turtle Island for its distinctive shape. This protected island is a nesting ground for the famous Caretta-Caretta turtles. Enjoy a relaxing swim, discover its pristine beaches, and admire turtle nests from a respectful distance.

We continue our journey into the bay of Laganas, where you'll have the chance to spot sea turtles swimming freely in their natural habitat. Keep your camera ready — you might get the perfect shot of a turtle surfacing.

Our final stop is Pelouzo Island, a peaceful green islet with shallow, clear waters — ideal for a final dip. If desired, the captain can also include additional swim stops at some of the hidden beaches around the Vasilikos peninsula.

This relaxing and adventure-filled cruise offers breathtaking views, wildlife encounters, and unique memories before returning to Tsilivi Port.
