Fodor's Expert Review Marathonisi Island

"Turtle Island," as it's known, is one of the most important breeding areas for the Caretta caretta loggerhead turtle in Zakynthos. It lies off the shores of Keri, west of Laganas, and is made up of two small islets, with a pine-speckled hump and a thin sandy outcrop that even makes it look like a turtle. It falls within the boundaries of the National Marine Park. Trips may only be made during daylight, though the chances of spotting a turtle are high. If you do go with a local company, try to book with Nefis Travel, which is authorized by the marine park and works in tandem with sea turtle conservation organization Archelon. Boats can be boarded at Agios Sostis, 2 km east of Laganas.
