An amazing experience! My 5 year old and I went on a Reef Tour and had an amazing time. The tour guide was extremely knowledgeable on all the marine life we saw and was very excited to see so many sea turtles, even explaining how you can tell their gender! The experience was incredibly educational and my 5yo was loving being able to see all of the fishes, and talked about the tour for days! Definitely recommend this tour (and they have a mermaid tour for a more magical experience with the little ones!)

Went with toddler daughters for Mermaid. It was perfect. Great captain and staff. Was most memorable part of trip for the girls and almost booked it again but ran out of time!

We had the most amazing experience on the undersea explorer!!! I went with my son 1.5 years and husband. The boat is so unique I have never seen anything like it before. We saw tons of sea turtles, fish, coral, and a giant eagle ray! The crew was extremely friendly and knowledgeable of all questions. My biggest ask would be you guys also add an adult cruise! Adults need to experience this too it is like snorkeling without the effort just SO cool!! LOVED IT highly recommended and would definitely go again!
