As a proud Zakynthian, I’ve watched countless visitors fall in love with our precious Marathonisi, a small uninhabited island that we locals affectionately call “Turtle Island” due to its distinctive shape and special inhabitants.
Nestled in Laganas Bay, this turtle-shaped paradise serves as a vital nesting ground for our beloved Caretta caretta sea turtles. The pristine white sandy beach on its northern coast isn’t just another pretty shoreline – it’s a sacred place where these magnificent creatures have laid their eggs for generations.

When you approach Marathonisi by boat, you’ll first notice its striking appearance: lush greenery cascading down limestone cliffs, contrasting beautifully with the crystal-clear Ionian waters. The main beach, with its powdery sand and shallow waters, offers perfect swimming conditions, while the blue caves on the island’s southern tip provide excellent snorkeling opportunities.
The best time to visit is between May and October, but remember – we take our role as turtle protectors seriously. The beach is carefully monitored, and certain areas may be marked off to protect turtle nests. Don’t worry though; there’s plenty of space to sunbathe and swim while respecting our shelled friends.
To reach Marathonisi, take a boat from Agios Sostis or Laganas harbor. Many local boat operators offer trips throughout the day, with some including stops at the nearby caves. My personal tip? Book an early morning tour when the waters are calmest and the light is perfect for photographs.
Remember to bring:
- Water
- Snorkeling mask
- Sun protection
- Camera
- Some small change for the boat ride
As someone who’s spent countless summers guiding visitors around our island’s gems, let me share some insider knowledge about Marathonisi that you won’t find in typical tourist brochures.
Perfect Timing & Transportation
- Best viewing hours: 9:00-11:00 AM for turtle spotting
- Boat prices: €15-20 per person for standard trips
- Private boat rentals: €80-120 for half-day (worth it for photography enthusiasts)
- Trip duration: Typically 2-3 hours including swimming time
Local Tips
- I recommend stopping at a bakery for fresh spanakopita before your trip
- Bring frozen water bottles - they’ll melt gradually keeping drinks cool
- Bring a waterproof camera if possible
Seasonal Highlights
- May-June: Best turtle spotting
- July-August: Warmest waters (26-28°C)
- September-October: Quieter periods, still warm enough for swimming
Common Mistakes to Avoid
- Don’t rely on afternoon visits (winds pick up)
- Skip crowded mid-day tours
- Don’t forget reef-safe sunscreen
- Avoid noisy hours (turtles are sensitive to sound)
Remember, Marathonisi isn’t just another beach destination - it’s a living nature reserve that we’ve been blessed to share with visitors. Treat her with respect, and she’ll reward you with memories that’ll last a lifetime.
