A quiet boat ride
My wife and I were staying near Seven Mile Beach and booked this for something different one evening. Honestly it ended up being one of the highlights of the trip. Quiet boat ride, stars overhead, and glowing blue trails in the water every time you moved your hands. Super relaxing and really unique.

Good Service
At first we almost passed on this because we weren’t sure if it would really look like the photos, but wow… this ended up being one of our favorite nights in Cayman. The boat ride was peaceful and once we reached the bay the water looked almost neon blue around us. Really memorable experience.
O
Highly recommended!
We almost didn’t book because it sounded too good to be true, but the water really does light up. Tiny blue flashes followed every movement in the water and it looked incredible once your eyes adjusted to the dark. Easy pickup from our hotel and everything ran smoothly from start to finish.
B
Efficient, comfortable way to see something truly unique
This was a great trip. They were very efficient a great way to spend a few hours on the sea and observe the bioluminescence phonomenon. It was quite powerful when we went on April 23: They said it is better to during early moon - not half-full or above. (We were just shy of half moon and could see it very well). They offered a pick up service, or in our particular case, we could meet the boat at the dock on the west side and some people were picked up by the boat near rum point.

Very cool experience!
This was a very cool experience. Getting in and swimming and seeing the waters light up glowing blue made it amazing. The guides were very informative about the starfish and jelly fish as well. The whole experience was awesome.
