tour guide was great and cave swimming was excellent, but this tour made me and my friends uncomfortable in many ways. When a turtle is spotted boats swarm around the turtle (3-5 boats at a time.) The boats continue to follow one turtle for extended time. I noticed that the turtles progressively attempt to stay under the water longer and longer to avoid the gawking and get the boats to leave them be. In comparison to other boats this one was relatively respectful, as it kept a fair distance from the turtles, but I would not recommend this to anyone who cares deeply about animals.

The tour itself was good and well organised. We booked it before we went on holiday to ensure we had something lined up but having spent a week in Zakynthos in hindsight I wouldn't have booked this tour. There are better ways to see the turtles. We swam in the sea at Kalamaki beach and saw turtles, and hired a glass-bottomed kayak for 10 euro and saw a turtle at the same spot. We did see on a turtle on our boat trip, but I felt uneasy about the distress to the turtle with another boat also crowding it and a lot of fuel and fumes seemingly polluting its natural environment. The stops to swim on this tour were great but you can do that on lots of smaller boat trips that don't stress out the wildlife.
