It was very simple and straightforward; you can explore everything and have fun even without a skipper. Booking was flawless, and the instructors were very friendly and helpful.

Nice boat with spacious benches, which is ideal with small children. Swimming from the boat, both in a bay and at a small beach, was lovely. We actually saw two large turtles as well: one in the harbor (it is being fed, though) and one at sea.

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 !

Great day! The program is well put together, an effort is made to find turtles. We swam wonderfully and enjoyed the beautiful surroundings. And... we also saw a turtle, despite it not being the right season. If you have the chance, sit at the front of the boat, wonderful! The captain makes an effort for his passengers, despite the fact that we were of course number 20,000!

The scenery was amazing. We even saw a turtle. The skipper was very experienced and had great control of the boat. Top-notch.

Super nice boat there is nothing for sale so bring your own food and drinks. Nice sailing no stories but stopping at the right points. Just push through so that we would be picked up from the hotel, they first acted as if they did not know that the transfer was included, had a great day
