Booked as our excursion while on our cruise. Quick EASY walk from the port to board the ship. ALL staff were kind and engaged with tourists from the moment we boarded the ship. The ship was CLEAN and well maintained!! Reyna was GREAT explaining exactly what and how to use the BOSS. The divers once in the water were TOP NOTCH making sure each one of us were READY and comfortable!!! Stayed with us every step of the way and took pictures for us (none to post just yet- forgot to use my phone I was loving the experience- and took an underwater camera) Pack plenty of sunscreen!! They had some snacks, water and kool-aid for the guests. I’d suggest having your OWN snorkel mask 🤿 to use while waiting on your groups turn to boss you DO get to snorkel on your own. BOOK THE TOUR it’s so COOL!!! My only wish - it could’ve lasted LONGER

Hands down THE BEST experience & must do water activity while in St Thomas. Not only did we get plenty of time to snorkel at our own leisure, but THE cherry on top was the underwater scooter… BEST EXPERIENCE EVER - I felt like we were in an episode of Mario karts hahaha

Amazing experience. Divers were very patient and gave detailed explanations for those who cannot swim. I would definitely do this again

What an absolute blast! We enjoyed every minute of this excursion! Water was choppy and we had a brief rain (it’s the Caribbean, it’s expected), but there was plenty of cover to get out the ten minute rain that passed through. Upon arrival, the instructions and briefing was easy and interactive, with a few dad jokes thrown in, that were greatly appreciated to lighten the mood! The scooter are extremely easy to operate. U see TONS of marine life, many many fish and a shark here and there. The snorkeling, u make it what u want to! Cruise the shoreline and see many coral and fish there as well at your own pace. Crystal clear views in 40 foot of water and down to 6 foot of water in the snorkeling area. The only thing I’d like to have to make it better was a bit more time in the underwater scooter, you get 30 minutes roughly and snorkeling the rest of the time, but, it is NOT an issue! I highly recommend! Worth every penny of admission. Best for adults but so simple younger children can do it as well. If you read a bad review, ignore it, those people are just looking for something negative to say! This is a MUST when visiting St Thomas!

Experience overall was good. Good snorkeling and boat was good. The submersible was a unique experience that I recommend. Although, I was put in unlucky #13 and it did not function very well. Propulsion was a snails pace even compared to the other submersibles. We are down there for only 20 min with them. The life vests should have two straps around you (one around waist and another up through groin). The one for the groin was intentionally cut on all of them, which is stupid because the vest rides higher up on neck once in the water or can slide off over your head. The experience looking through the bubble on the submersible is a little surreal. Depth perception is warped when looking down or to the sides, but it is a very easy going time breathing. It is as if you turn a cup over in water. You breath in the air pocket that is formed and with the compressed air from the tank attached to the submersible.

This adventure was really neat. We really enjoyed snorkeling with the fish in the bay. I was interested in riding the sea scooter and that was a lot of fun. Great team

We really enjoyed this adventure. I took my adult son while we were in St Thomas. The crew was great and we had a great time exploring underwater.
