What to expect

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 tell give you the lowdown on its work.

    Amazing views of the cost, great information provided throughout! Seeing turtles aren’t guaranteed, we think we saw one but it was still a wonderful day regardless!

    Tui rep was not overly friendly but was more with what we felt her own nationality group. Felt like she wasn't there at all. I approached a different rep and she was helpful and cheery. There was alot rude people on this cruise. The snack bar people were lovely, snacks available was really good and good prices. Although they tried, we did not see any turtles. We were also not given alot of time on Keri island. A quick toilet stop and a rush to return coach bus. Disappointing.

    The boat has more space on it. Snack bar was friendly but had little variety. The toilets had no seats which was the worst thing. That invited people not to sit but hang and they get very dirty and wet. Not expensive items for owners and I think essentials in ladies toilets

    The whole experience was a waste of time and money. Why take people on such a cruise, when there are no turtles to be seen because of the weather and time of year. Other operators were offering a similar cruise much cheaper and some even included landing on the island. There were no floatation devices on offer for non swimmers. This cruise was very long and boring. I could have stayed at home and gone away on a ferry to from Dover to Calais!!!
