Excellent organization! Very friendly staff! :) We even drove a detour to see the turtles. Drop-off and pick-up were flawless. We would definitely use them again!

Captain Alexandros was a fantastic and very entertaining tour guide. This tour far exceeded our expectations. We were very surprised that no one else gave the crew any tips...

Great tour at the end of September, although most of the turtles were already migrating, we were able to marvel at one. The swim stops were wonderful.

The landscape is just sublime, thanks to Panagiotis the captain who did everything to make the most of it! A great captain and a great guy! I recommend to everyone. Everything is taken care of, masks, food, drinks, you don't have to worry about anything. Thanks again !

An incredibly fun boat trip with a great captain. A unique kind of boat with a glass bottom so you could see the turtles swimming beautifully. Dog-friendly!

Fun activity to do! Boat looks good, nice system with a sailing app so you know exactly where you can/can't and can't sail so you don't get to lie on rocks. Nick is easy to reach. Highly recommended, no mass tourism, but heart for business!
