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 😉
Unique experience❤️

5.00The experience with Seatru in Sesimbra was simply fantastic! The boat ride through the caves and rocky formations was amazing, with right to very interesting explanations from the captain and crewman about the area. The Ribeira do Cavalo looked like the exit of a postcard, crystalline water in turquoise blue tones, perfect for diving and exploring. The staff was impeccable, super fun, attentive and always making sure everyone was at ease. One of those days that are kept in memory. I recommend 100%. Thank you for the fantastic experience and the good moments!
Amazing experience

We loved it! 👏👏👏 Excellent team, always very fun, good luck to Marcelo and Diogo, very communicative, they left us very comfortable from the beginning to the end of the experience.

5.00It was a good experience and good organization, there was always a person responding to our questions. The trip was very nice, although we were not very lucky and the water was dark that day, we saw some fish, but not much. But anyway the Arrabida coast and beaches are beautiful, we could take a bath and all in all it was a very pleasant trip.
Better? Impossible!

5.00Exceptional experience! Both in the fact that the boat is all transparent where we can see the bottom of the sea, the marine life, immense fish, as well as in the views: the sea and the whole coast, the beaches etc; We had many unexpected friends (Golphins), it was really magical, we still dive into the waters worthy of the Caribbean and of course: Marcelo and Vitor were TOP! In addition to great guides, acquainted with the area and always taking care of our safety, they also gave tips for excellent restaurants! Super good morning! I highly recommend.
