Turtle Island Beach offers safe swimming in its clear, calm waters, but visitors should be aware of its protected status as a nesting site for loggerhead sea turtles. Swimming is generally permitted in designated areas, but it's crucial to respect all signage and guidelines to avoid disturbing the turtles or their nests. Boats are often restricted from approaching too close to the shore, ensuring a peaceful environment for both wildlife and swimmers. Always maintain a respectful distance from any marine life.

The best time to visit Turtle Island Beach to potentially see loggerhead sea turtles is typically during the nesting season, from May to October. To avoid the largest crowds while still having a good chance of spotting turtles, consider visiting in the shoulder months of May, early June, or late September. During these times, the weather is still pleasant, and the number of visitors is lower than in the peak summer months, offering a more serene experience.

Access to Turtle Island Beach is primarily by boat, as it is located on a protected island. Many tour operators in Zakynthos offer organized boat trips to Marathonisi, often including stops for swimming and snorkeling. You can also rent a small private boat or join a water taxi from nearby ports like Laganas or Keri. Land access is not possible, so a boat trip is essential to experience this unique beach.

Due to its protected status as a nesting site for loggerhead sea turtles, there are no permanent food or lodging establishments directly on Turtle Island Beach. Visitors should plan to bring their own snacks and drinks. Some boat tours may offer refreshments, or you can find options in the nearby coastal towns before or after your visit. The island's pristine nature is maintained by limiting commercial development, preserving its natural beauty.

Turtle Island Beach is uniquely shaped like a turtle, adding to its charm. Its most distinctive feature is its role as a vital nesting ground for the endangered loggerhead sea turtle (Caretta caretta). The crystal-clear, shallow waters are perfect for snorkeling, allowing visitors to observe marine life in a pristine environment. The island's untouched natural beauty, combined with the chance to witness these magnificent creatures, makes it a truly special and memorable destination.
