I booked just 20 minutes before. The confirmation was very quick and we were taken care of immediately. As a bonus, we saw a turtle. Thank you to the team.

It was a fantastic boat trip at a great price! At first, there was a long queue, and we wondered how it would all work out. But the trip was worth it in no time, and we all had a seat on the boat where we could see everything. The guide was excellent; he turned the boat around so everyone could enjoy the view. We saw three turtles, and then we continued on to stunning natural scenery: turquoise water, caves, and rocky outcrops. It was simply fabulous. Finally, jumping into the crystal-clear water from the boat was a refreshing and amazing experience! For the last 20 minutes, we went to the beach, where we could see the turtle nesting sites in the distance. For those of us who hadn't dared to jump in the water, like me, this was a great opportunity to hop into the beautiful water! Recommendation: bring plenty of water and, especially for children, food! I'd love to do it again!

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.

It was perfect. We went around the island. If you want to admire all along the excursion. Stand on the right side of the boat.
