5.00We were fortunate to be on the island during a new moon. We were picked up by Mikel who I believe had said he was the owner at our hotel and were also dropped back off after the tour was complete. Boat was great- we all had skin suits & boots to wear in the water. Was amazing to be in the water and also to look up at the star filled sky, it was simply amazing.
Amazing experience

5.00We had a blast on this tour. It’s a really unique experience and we’re happy we chose it. The boat ride to and fro was very nice and the guides very knowledgeable. Be prepared to snorkel (we didn’t know/pay attention), and bring a towel (we forgot that too).

5.00Spectacular bioluminescent snorkeling tour. The light show under the water was wonderful and the guides were excellent. It was also a clear dark sky night with wonderful stargazing. The boat was fast and comfortable.

5.00I have been on a bioluminescent tour before. I should call it "bioluminescent". Because the first one I went on was baloney. This one is the REAL DEAL. George's Watersports was a fantastic outfitter. We used them for Stingray City earlier in the day as well. Great guys and boats. With George's, you get into the water and snorkel to best see the glowing plankton and boy, it is 10x better than viewing from above the water. Not. Even. Close. Bursts of sparkles flings from your fingertips when you are looking into the water. It is downright magical. Can't even believe that was real. The tour gives you a stretchy body suit and rubber swim shoes. You go into the water with a pool noodle. Why? Because it's only 5 feet deep and you are not to touch the bottom. Partly because the upside down jellyfish live down there and you don't want to mess with them (although it sounds like they're not all that bad) but also to keep the sediment in place. The shoes will protect you if you happen to graze the bottom. The jellyfish do not swim around you. They are not a big deal at all. The guides will take your picture from above and those look kinda cool. But again, a picture above the water simply does not do this experience justice. Viewing in the water is breathtaking. You stay right next to the boat so it's not scary or dangerous. The plankton are exceedingly numerous and never run out of energy. This was the best of our many adventures on Grand Cayman.
Great experience!
