The next stop is Marathonisi, often called Turtle Island due to its shape. Here, visitors can step onto the golden sands of the small beach, perfect for lounging, swimming, or even taking a quick nap under the sun. The tour allows about an hour at this location, giving plenty of time to relax or enjoy a drink from the boat bar.
Swimmers can take advantage of the calm waters, while those seeking a break from the sun might enjoy the shade or a snack. It’s a delightful way to unwind in a paradise-like setting before heading back.

This stop is ideal for relaxing with a drink or enjoying a quick bite, making the experience more comfortable and enjoyable.

The combination of Keri Caves and Marathonisi offers a mix of spectacular geology and relaxation. The white limestone cliffs at Keri create a stunning environment for swimming and photo opportunities, while Marathonisi provides a gentle beach for unwinding.
