What are people saying about St Thomas

Kelly_S, May 2026

We had a great time on...

We had a great time on the BOSS and the crew was wonderful! The crew was knowledgeable and fun. Snorkeling was at your leisure or you could stay on the boat and snack, sun or just relax. The best part is the 30 minutes scooter tour!!! So much fun. I was surprised to learn that you can participate even if you don't swim. I watched the crew walk a couple through the process and neither of them could swim; they were nervous; but post scooter ride were thrilled they had done it and would do it again! I highly recommend this excursion.

Floating with Style with a true sailor

Captain Kendall is awesome. Quick with a story, happy to be there, and does a great job balancing captain duties with crew duties. He takes you to less populated snorkeling sites with opportunities to see more interesting and vibrate sea life. His sailing experience makes being under sail power look like a breeze.

Fun Day on the Water!

The catamaran tour was great! Jolene was our captain, Matt and Sensi took care of us on the boat. They were all wonderful, snacks while we cruised to the snorkeling location, and all the adult beverages you want after snorkeling, and enjoyable relaxing time in the water when we visited Lime Out for lunch. If you need shade, there is searing inside, otherwise bring plenty when lounging outside.

Had a great time...

Had a great time snorkeling with Dillon and Brandon! They were great hosts, were very knowledgable about the sea life that we saw, and brought the energy. They didn’t limit where we could explore (within reason) unlike some of the other experiences we have been on. Would recommend this trip to those looking for a smaller group scene.

Your experience begins with a scenic sailing adventure of about an hour, offering incredible views of the surrounding islands. From there, you’ll stop to snorkel at a secluded island, where you can spot sea turtles and a wide variety of colorful fish. After snorkeling, sit back, relax, and enjoy the peaceful sail back.

Loved it!

The booking was easy. They followed up with all the necessary details. The meeting point was easy to find. Our captain, Brayson, was funny, friendly, knowledgeable and helpful. We loved the two islands. I just wish that day had brought us more turtles. The equipment was in good shape and clean as well as the boat. Would definitely do it again!

The best excursion we've ever been on ! Not one complaint. Aaron , Jake & Christion took us to the best places to see fish , stingrays & turtles ! We were in no hurry. They served us beverages & a local favorite called the " Pain Killer" We had fresh fruit on our way out and lunch served after our first spot. Fantastic tour & we will be doing this one again !!

John was a great guide...

John was a great guide and very knowledgeable for the tour. This was pretty informative including some details about fauna and flora as well as some history. The area to snorkel was great and saw schools of huge Tarpon I believe. Plus a Stingray and other sea life. I would highly recommend this excursion.

Snorkeling with Sea Turtles at St. Thomas

Lex_M, Mar 2026

Yes, You Will See Turtles 🐢

This was my first time booking through Viator and I was honestly a little hesitant, but this ended up being one of the best parts of our trip. The biggest difference is that this is an experience-focused tour, not a volume/throughput excursion. We were about 20 minutes away from the cruise port to a quieter area (Brewer’s Bay), and it made a huge difference in what we were able to see. Our guide was fantastic — She didn’t just drop us in the water and hope for the best. She actively found wildlife for us, dove down to point things out, and gave clear instructions (especially to the kids) on how to respectfully interact with the animals. We saw multiple sea turtles (including one with a remora), a manta ray, a sea urchin, fish, and a queen conch. It felt like a curated experience, not random luck. They also provided proper gear (life jackets, etc.), which made it accessible and comfortable. If you’re deciding between a large cruise excursion vs. something like this, I would 100% recommend going with a smaller, local operator. The difference in quality and care is very noticeable. Would absolutely book again.

Jeffrey_V, Mar 2026

Phenomenal Tour!

I can’t recommend this tour highly enough. It’s not just about an incredible snorkeling experience—it’s also the perfect way to get out on the water and fully soak in that Caribbean vibe in the limited time we had off the ship. Our crew—Captain CJ, John, and Sydney—were fantastic hosts: fun, knowledgeable, and always going the extra mile to make sure everyone had an amazing time. The boat itself was ideal for the trip—comfortable, well-equipped, and perfectly suited for a relaxing day at sea. An unforgettable experience all around!

Parasail Experience in St Thomas

BEST part of our vacation!!!

This review is written by the owner of this account’s daughter, Angelina. The first time we went, it got delayed due to rain while the pair before us was about to go. They handled the situation amazingly and it made me feel much safer about going on the ride. When we went on the ride, it was incredible. Coming from someone who is not fond of fast rides, it is perfect for someone who likes adrenaline but not the fast rides and sharp turns. Most of our time in the air was very slow paced and relaxed. The crew, Chris and Jay, were WONDERFUL. They were incredibly funny and welcoming. It was honestly my favorite part about this trip. I highly recommend. However, you never know what the circumstances will be. This ride relies heavily on how the weather is. Make sure not to schedule this trip on the last day you are here to make sure you don’t miss out from weather delays.
