A really lovely way to see around turtle island..swim stops included.
We have seen a turtle. Then we went to the cliffs at Keri-point. The stop at the turtle-island could be shorter, since there is little space and little shade. It was a very nice trip with an enthousiast captain!
Thank you very much for your kind review! We’re delighted to hear that you enjoyed the trip, saw a turtle, and had a great time with our enthusiastic captain. We also appreciate your feedback regarding the stop at Turtle Island. We take all comments into account as we continuously work to improve the experience for our guests. Thank you for choosing us, and we hope to welcome you back to Zakynthos again in the future! 🌊
Really nice trip. Very appropriate timely, lovely with the two bath stops. A nice trip and the captain had complete control of the boat
Thank you so much for your wonderful review! We’re delighted to hear that you enjoyed the tour, the two swimming stops, and especially seeing a turtle. It’s great to know that you felt safe and well looked after by our captain. We truly appreciate your kind words and hope to welcome you back to Zakynthos for another unforgettable experience! 🐢💙
Three of us took this boat trip and we weren’t disappointed. We got to sea the turtles swimming in the sea then got a trip to the caves where we were able to jump off the boat and have a swim. (There is a ladder down to the water for older people - like me!) Then on to a beautiful beach where we were able to do a bit of snorkelling. All in all it was a great trip and a real bargain at the price. The Captain was great and even took photos for us from his vantage point at the front of the boat.
Thank you for taking the time to share your experience! We're so pleased that the tour lived up to your expectations. Seeing the turtles in their natural habitat, swimming in the crystal-clear waters of the Keri Caves, and snorkeling at the beach are some of the highlights we love sharing with our guests. We're especially happy to hear our captain made the trip even more enjoyable with his helpful attitude and memorable photos. We hope to welcome you back for another adventure the next time you're in Zakynthos! 🐢🌊📸
We had a fantastic experience with seeing real tutles, rocks and caves. The boat ride was good withoot big waves. Lovely that it was 2 stops for swim and snorkling. On turtle Island the flowing small restaurant offered good prices.
Dear Lina, Thank you so much for your wonderful review! We're delighted to hear that you enjoyed seeing the turtles, exploring the beautiful caves, and swimming in the crystal-clear waters. It's great to know the sea conditions made for a comfortable boat ride and that you had time to enjoy both swimming and snorkeling stops. We're also happy you enjoyed your visit to Turtle Island. We truly appreciate you choosing our tour and hope to welcome you back to Zakynthos for another unforgettable adventure! Best regards, The Escape Tours Team
The tour itself is lovely, the captain we had was very knowledgeable and even with limited English he was able to tell us a lot about the turtles and the islands. Plenty of time to see everything and to swim, especially swimming on Turtle Island was an amazing experience; I recommend bringing a snorkel. The boat has a glass bottom, as advertised, it is however much smaller than expected and in a crowded boat you get no chance to look. However the water is clear and you get to see plenty just on the sides of the boat. Getting on the boat however was a less pleasant experience, we got a message to arrive 20 minutes before, many others arrived around 10 minutes before, the captain of the glass boats kept dismissing everybody's question saying; we have time. I understand that we were not in a rush, but people were unsure where to gather and any question was dismissed. By the time we were supposed to leave, there were over 50 people on the dock waiting for one boat. Only then it became clear that a second boat would come, thankfully. Even then, once we finally left, one of the two boats left with over 30 people on board, which was incredibly uncomfortable.
Thank you for taking the time to share your feedback and for your kind words about the tour, our captain, and the beautiful scenery of Zakynthos. We are delighted to hear that you enjoyed the swimming stops, Turtle Island, and the overall experience. We would like to clarify a few points regarding your comments about the boat and boarding process. The tour you booked is a shared group experience, and during the peak summer season the boat may operate at full capacity. The maximum number of passengers is always within the licensed limit set by the local port authorities and safety regulations. For travelers who prefer a more exclusive experience with additional space and flexibility, we also offer private boat tours. Regarding the glass-bottom feature, it is exactly as described in the tour information. Visibility may vary depending on seating arrangements and the number of guests onboard, although the crystal-clear waters often provide excellent views from all areas of the boat. We also appreciate your comments about the boarding process. We ask guests to arrive 20 minutes early to ensure a smooth check-in experience, especially during busy periods. We understand that communication at the dock could have been clearer, and we will work with our team to improve the boarding experience and provide more detailed guidance in the future. Thank you again for your feedback. We are pleased that, despite these concerns, you enjoyed the tour itself and had the opportunity to experience the beauty of the Keri Caves and Turtle Island. Kind regards, Escape Tours Team
At Nautilus flag boarded a boat for +- 23 people we sailed first to the turtles that we also saw swimming then along camio island where we had swam the day before, on to Cary caves but then the boat got problems, but quite coincidentally there was a boat that was not full and we could transfer now we were with ~40 people on the boat to continue the journey. On to Cary Caves sailed through, beautiful to see and still swam there, then to turtle island which is really just an island with the shape of a turtle. Stopped there and swam you can buy an ice cream at a boating shop Then we went to look for a turtle and can see it lying on the bottom. Then back to the harbor, where we saw our previous boat again uitvaren.Een nice trip of 3 hours everyone had a seat even after the transfer arranged so fine.
Thank you very much for your review and for sharing your experience. First of all, we would like to sincerely apologize for the inconvenience caused by the technical issue with the original boat. For clarification, the first boat had approximately 20 passengers on board, and after the transfer, guests were accommodated on another vessel that had available capacity. We strictly follow all safety regulations and passenger limits required by the authorities. If necessary, we can provide the relevant documentation and operating records that demonstrate compliance with these protocols. The decision to transfer passengers was made solely to ensure the continuation of the tour in the safest possible manner and to avoid canceling the experience. Passenger safety is always our highest priority, and we never operate beyond the legally permitted capacity. We appreciate your understanding and are pleased to hear that despite this unexpected situation, you were able to enjoy the turtles, Keri Caves, Turtle Island, and the swimming stops, and that everyone remained comfortably seated throughout the trip. Thank you again for choosing us, and we hope to welcome you back to Zakynthos in the future. Kind regards, Escape to Zante Team
We had plenty of space because very few people came along. Unfortunately the weather was not so good therefore not swimming. The skipper tried very hard to see sea turtles. On the way back we saw 1 and floated around to get a good look.
Hartelijk dank voor uw mooie beoordeling en voor het delen van uw ervaring. We zijn blij om te horen dat u voldoende ruimte aan boord had en ondanks de minder goede weersomstandigheden toch van de tour heeft genoten. Hoewel zwemmen niet mogelijk was vanwege de omstandigheden op zee, doet onze schipper altijd zijn uiterste best om onze gasten een bijzondere ervaring te bieden. Wat fijn dat u tijdens de terugweg toch een zeeschildpad heeft kunnen zien en rustig de tijd kreeg om hiervan te genieten. Bedankt voor uw begrip en uw vriendelijke woorden. We hopen u in de toekomst opnieuw te mogen verwelkomen op Zakynthos voor nog meer mooie momenten – hopelijk met zonniger weer! Met vriendelijke groet, Escape Tours Team
Fantastic experience, small boat with 18 passengers, the keri caves were impressively beautiful. Three hours was also fine in terms of duration, enough stops for swimming both near the caves and later from turtle island where we docked. The captain/skipper was a good mate, sailed us into the caves and made the afternoon truly unforgettable. Really more than value for money!
