Turtle Cruise to Marathonisi and Keri Peninsula

4/5
1712 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.

    Great day from beginning to end, good value for money, safety was well organised and the food on board was very reasonable. Only downside was having to walk to the bus stop at top of road which my husband found difficult as is unable to walk very far so had to leave hotel earlier to make sure we was on time.

    We had a great time. It was lovely to see the South side of the island, the keri caves and saw 2 turtles. The swim stops were amazing, especially the 2nd one in a stunning bay of Porto Roma. Transport to and from the hotel were great. There's plenty of choice for food and drink on board and staff were lovely. We had an amazing day thankyou 💗

    Excellent trip covering a wide area of the coastline. 2 swim stops but as it was a large 3 tiered boat there were a lot of swimmers in the water knocking into each other. Safety was a concern especially on the second stop when the sea had a stronger current and larger waves. We were advised to keep close to the boat, but that was not possible with so many people in the water. I would have preferred a smaller boat and be able to go into the smaller shallower coves.
