5.00A well organised and fantastic boat trip. Turtle spotting to start and we saw many of them plus info all about them. Keri Caves was next with a swimming stop and then on to the golden beach of Marathonisi. Would highly recommend.
Unforgettable and exciting!

4.00The excursion was originally planned for a Saturday but was postponed to Sunday. The boat was full but we were sitting at our ease. In addition, the captain is very friendly. We had a great time despite the weather that was not part of the game. We even had the privilege of seeing a turtle. However, it is very touristic and we were quite a boat one after the other.
Worth knowing before booking

2.00I’m not usually one to write reviews for excursions, but I thought sharing my experience might help others decide whether this particular trip is right for them. I went with a small group of friends and, overall, we were a little disappointed with the experience. One thing worth noting is that the boat is not docked at a pier or platform - you have to walk through the sea to reach it. We were advised by the guide that the water would only be knee-deep, but it was much deeper than expected. Unfortunately, the water in Laganas Bay was also not very clean, so we ended up soaked and quite dirty before the excursion had even properly started. The boat itself was advertised as “glass bottom,” however the viewing section was much smaller than we anticipated. Considering the overall experience, we personally felt the excursion was quite expensive for what was offered. We believe we spotted one turtle during the trip, although visibility wasn’t great that day due to the weather conditions. There was music playing onboard, but it was difficult to hear over the noise of the boat engine. That said, I do want to mention that the guides were very friendly and did their best to make the trip enjoyable, which we appreciated. Another downside was that we were dropped off far out in the water again at the end of the excursion, meaning that after finally drying off, we ended up soaked and dirty once more and needed showers as soon as we returned to our villa. Overall, the activity just didn’t meet our expectations, and my friends and I left feeling disappointed. However, we did a different boat excursion the following day (the Shipwreck Beach trip), and found that experience significantly better, so I’d personally recommend looking into that option instead.
Lovely getaway

5.00It was lovely, we saw a turtle. Swimming at the Keri caves with imposing cliffs towering over us was a real experience. Stopped at Marathonisi beach for a swim and spotted an octopus snorkeling there. Great captain/guide, Thank you!

4.00Information given wasn't upto date but the guy we talked to couldn't have been more helpful The sea was rough so we couldn't do some of Keri caves which was a shame we saw a turtle! The guy piloting the boat didn't give any commentary which would have been nice
Beautiful Island Views

5.00This is a wonderful experience, we went in September so the very end of turtle season, we were warned beforehand there’s very little guarantee of seeing them this time of year but we did see 1 big turtle!! Around the caves is very peaceful and beautiful sights, the caves aren’t ‘proper’ caves and more of just little holes in the side of the mountain, however, still very beautiful. Our skipper was very nice and extremely talented in controlling the boat I was so impressed in his control of movements. My dad’s hat blew off into the sea from the wind and the skipper stopped the boat to pick it back up!! Unfortunately, when we got to the beach it did rain so we didn’t stop to swim or stay very long which is a shame but a fault of no one’s and this experience overall is something I would 100% recommend.
Wow

5.00Nice trip :) a lot to see a lot to feel. Need to have swiming boots, very wet (seats, water from foof, water from splashes), so don’t take to much stuff. No life vest and toilet ob the boat or stops. Windy in the sea so if you sensitive take jumper.
