5.00Great experience all around. Guides were kind, helpful, and lots of fun. I am not a strong swimmer and was somewhat nervous, but they were thorough in their instructions and put me very much at ease. I would recommend this experience hands down.

5.00What a fun experience! My daughter (14) and I had a wonderful time on this excursion. The staff is very well trained and friendly! We saw several sea turtles from the catamaran. My personal scooter guide helped me find one while I was in the scooter as well! It was an amazing experience watching all the sea life while scooting around the ocean! We also enjoyed snorkeling prior to our turn in the scooter. 10/10 would recommend!
