Turtle Cruise to Marathonisi and Keri Peninsula

4.1/5
1571 reviews

Loggerhead sea turtles have been residents of Zante's beaches for thousands of years, and with a bit of luck, you'll see them first-hand on this boat trip. Join an expert local guide for an educational day out at sea, passing by nesting sites, swimming in hidden bays and spending time in the village of Keri. Bianca, one of our guides, says, ‘In just one trip, you get to jump into clear waters, cruise along the Keri peninsula and, with luck, see turtles.'

Available either in the morning from Zante harbour or the afternoon from Keri harbour, this half-day cruise is a real treat for all the family. You'll pass by the golden beaches of Vassilikos and Marathonisi, a pine-clad islet dubbed ‘Turtle Island'. The reason's simple – one of its beaches is a favourite turtle nesting site. Bianca, who's lived on Zante for more than 20 years, says of the scenery, ‘You can do this tour a thousand times and every day is different.' Be sure to keep a lookout for Loggerheads, and you may even spot a wild dolphin or two.

Plus, you'll sail along the Keri peninsula, cruising by its sea-plunging cliffs, caves and lighthouse before dropping anchor for a swim stop at the Bay of Oasis. In the small village of Keri, you have a quick stop to shop for souvenirs, relax in a typical taverna or hit the beach. What's more, a volunteer from local conservation group ARCHELON – the Sea Turtle Protection Society of Greece – will be on board to give you the lowdown on its work.

    It was a lovely afternoon out. We swam, we saw turtles and learned a little about the area and the turtles. The drink and snack bar was well stocked to keep you cool and not hungry. We even bought a photo graph and a magnet onboard as a memory. Good value.

    We had a great day on the boat trip, very enjoyable. Couple of good swim stops and the TUI guide kept us up to date on all to look at and what was happening. Unfortunately we did not see any turtles on the trip but had a lovely day.

    the transfer was very long from Akyles and the bus used was very very old with little air conditioning the guide could have given more information about the geology of the island and other species that live on it apart from the turtles. more stops for swimming would have been great
