Good Experience, Awaiting photos - Very safe and unique excursion. So glad to do it. We are ages 65-76 and were very confident in the care and attention of the SeaTrek workers. The only glitch is the photos- we are still waiting for a link and a way to purchase them. We hope SeaTrek will provide those soon!

Great for the whole family. - From the boat crew to the safety divers this whole team was great. We had our elderly mother with mobility issues and our 11 year old daughter (so both ends of the spectrum). Everyone was so patient and accommodating. We could not recommend this company enough.

Fantastic underwater experience - The Seatrek excursion was great. We weee a little nervous about the helmet and set up but the crew explained everything clearly and were with us every step of the way. The underwater walk was easy and we saw loads of fish and even an octopus. We highly recommend this tour

Great experience - It was great. I hate snorkeling, but want to go underwater to see the fish. I was able to do this and it was fun. The crew was very professional and I felt safe underwater with them watching.

Nice boat ride - The your was as advertised. People very helpful and friendly. My wfe was unable to get her ears and balance and could not do the walk. It was interesting and I found the displays were old and rails not in good shape. As for my last review I would probably not do it again. The price is what I would a bit excessive. But very pleasant staff.

Trip Cancelled, Poor Communication - Tour got cancelled due to “weather.” Stood around with no notice for nearly an hour on a dock before a guy walked up, asked if anyone was there for SeaTrek and that it was cancelled. On a positive note, Viator was very helpful in getting me a refund.
