I had such a great time snorkeling with Silent World Dive Center. Aron kicked things off with his laid-back humor that instantly made everyone feel comfortable, and Emily kept everything running smoothly with her calm professionalism. The reefs were honestly serene to float over. The water was clear, the colors were gorgeous, and it felt peaceful in a way I didn’t expect. The whole trip just felt easy and enjoyable from start to finish. I’d absolutely go out with them again.

The boat trip out to the snorkel site was very calm and smooth. Captain Jeff and first mate, Emily made things very easy and relaxing. Captain Jeff played '70s rock music for the trip which was very fitting. Overall had a very wonderful experience. Would definitely do it again.

We had a great time on the Calypso with Captain Jeff and first mate Emily, both were very professional and were wonderful. Lots of fish and saw Christ of the Abyss. Super cool. Boats were in tip top shape and the facilities were clean, new and well stocked.

Great trip! Captain Jeff was a great navigator and First Mate Jolisa made sure we were all informed and safe. Saw lots of marine life and Christ of the Abyss. Loved it!

The 4-5ft waves were way too high for us to enjoy the snorkel trip and they only did one reef, not the one with the statue which would have been really cool. I know they technically don't know how high the waves will be, but it would have been so so much better for the crew to reroute to a calmer place. Even the other families on the trip had trouble getting their kids past the high waves to see any fish. Only one of mine was able to, but the company easily refunded us for that inconvenience, so I would still highly recommend. We took Calypso, boats are just okay, there isn't any frills.
