This tour is an absolute gem of an experience. If you are looking for a relaxing time out at sea with fun, knowledgeable local guides, book this tour! The boat is small (max probably only 20 people) and offers a more personalized feeling tour experience. Dillon and Mieshak (spelling is probably wrong so I apologize!) were our incredible captain and crew. They shared homemade banana bread and the best rum punch I've had in the Caribbean. We passed over several reef sites and the Andes shipwreck, and then stopped at a beautiful beach to have time to swim. I can't recommend this tour enough!

We were on our anniversary/honeymoon and this was our first excursion and it was such a great experience. Our captain and first mate were super nice and friendly showing us some really interesting and cool things in Antigua. We would definitely do this again with the same company!! Completely 5 stars!

Not much to see or do on this tour. We were disappointed. Birds were far away, no other animal life seen. Beach was OK, but there are beaches everywhere on this island. We could not visit the island and had to stay on the beach. We saw very few corals from the glass boat, and it looks like they might be dead or dying..

Amazing!!! The crew was wonderful and a very cool transparent boat. Didn't see a ton of fish but the whole experience as amazing. We have 10 in our family on this tour. We were all on a 7 day Cruise in the Caribbean and this was everyone's favorite excursion that we did. Thank you soooooooo much to Cam and Trevis were great!!!

Trying to get in boat was not easy due to high sides we booked the trip to see the fish but couldn’t see any thing on the way back from the beach the driver of the boat beached it we were in boat on sea when we had bad waves and it nearly turned the boat over as front of boat was stuck on beach and the waves were coming over and water was coming in boat and life jackets were floating the people on sandals beach came to help to get boat afloat so we set off again and we had to stop in middle of sea as water had got into fuel so they had to refuel the boat all the way back they were bailing out this was not well run or organised to a standard you would not expect it was a very frightening experience which I wouldn’t want any one to have the experience we had

Booked through Sandals. Trevis was a great captain. I can't imagine going with a better captain. Visited a beach only accessible by boat. Rum punch and banana bread on the beach. What could be better Water was a little cloudy due to storm the previous day, but not their fault. Sunken ship was really neat to see only a few feet below the surface.

I went on this tour on my birthday with friends and the team made my day very special. My friends and I had such a good time on the tour. What I loved the most was that the team prioritized safety and ensured we had fun in the safest way. I highly recommend.

The tour guide team was highly professional and well-informed about the island, sharing relevant details to enhance our understanding of Antigua's history. The captain was a engaging speaker with a calm demeanor, making the experience enjoyable. The transparency of the boat allowed us to observe the stunning ocean depths below, which was truly magnificent.
