We went on the boat tour yesterday morning to watch dolphins, and it was magical from start to finish. The crew were lovely, welcoming, and very professional. You can really tell that they love what they do and that they respect the animals.
We were lucky enough to see several dolphins up close, in a beautiful setting with a relaxed and friendly atmosphere. The boat was comfortable, and the explanations were very interesting.
An unforgettable moment during our stay. I recommend this activity 100%! Thank you again for this wonderful morning ✨

Highly recommend Sea EO to anyone visiting the area - definitely one of the highlights of our trip!

Bart joined us on the tour and he was really friendly and very knowledgeable. We went far out to sea to see the dolphins. But we didn't get too close to the dolphins, they got closer to the boat on their own. I liked that. (...)
