5.00Fun and Unique Experience! This was such a cool tour! The boat ride was smooth, and the crew was super friendly. The water actually glows when you move it, which was really fun to see. We also stopped at Starfish Point, where we got to learn about the sea life. Definitely something different and worth doing in Grand Cayman! Great Tour and Friendly Crew

1.00Travelled with family on 23rd dec night. There was no such bioluminescence in the bay. It was all funny to spend this much money for literally nothing. Crew & staff was very nice but the timings were told to be 6:30pm to 9:30pm. But we were back by 8:00pm lol. Felt like little scammed with this activity specifically
