5.00A very good and different experience! Being able to look at the bottom of the sea and the life that bubbles there takes us out of the day-to-day bustle and connects us to Nature. Marcelo and Diogo have great energy and let us know beautiful things. You see they like what they do. Super available and well disposed. The highlight was undoubtedly the break for a diving! We took our 10-year-old nephew who also loved the tour :)

5.00We had the Clearboat experience and it was incredible... Marcelo and Diogo made this experience worth it. They showed us the roughest points of the coast and told us about various curiosities. Very interesting and to repeat again. Next time will be the clear kayak 😉
