This 2-hour adventure begins with a short scenic 10 minute boat ride from Great Bay to Little Bay, where over 300 sculptures transform the seafloor into a breathtaking gallery teeming with marine life.

It’s one of a kind. And the history of how they created those sculpture was very interesting. The guys are nice and friendly and knowledgeable.

Short and informative tour. The guides, Tyrell and Daves, were awesome! The water was calm today and the fish were very colorful. We even saw a turtle. I highly recommend

Beautiful, fun, amazing. We were well taken care of by the crew. Clear and extensive introduction about sea life and the sculptures - made it even more engaging. Also clear instructions on safety, but no problems at all. Good captain, caring host (and calm sea; probably helped too).

Great crew, about 45 min snorkel time. I was not expecting much, but it was actually an amazing time. The 300 underwater statues were really cool, lots of fish.

This was an amazing excursion. We loved having the underwater park to ourselves so you didn’t have a lot of snorkelers crowding you like some of the other tours. Our guides were absolutely fantastic!! The history of the underwater park was so neat! Best excursion of our cruise!

The experience was new and captivating. Although I typically avoid deep waters, the helpful captain encouraged me to participate. My son and I saw many types of fish and even turtles. The statues play a vital role in creating homes and food for marine life, and I appreciate what they do for the ocean. Everyone should have the chance to enjoy such an adventure..
