It was very rough and many ppl Got sea sick. Not a ton of fish either. They lack the experience, music etc. the crew was awsome I will say that. Very confusing when you book you have to go to one place to check in and then another to catch the boat we almost missed it.

We were so impressed by how easy the whole process was! I brought my four year old, who wasn’t sure about the whole experience at first, and Justus and Joe were so patient and kind. Seeing the reef and all the fish was amazing. Our three generation crew (grandma, mom, and kid) had a blast.

Great and knowledgeable crew. Perfect for beginners or those who have snorkeled/dove before. It was a nice, short boat ride out. Good amount of time on the reef.
