  • This was a real neat experience. If you can not get in the water, I do not know if it would be worth it, but when in the water it is really awesome. They provide you with full face mask which allows you to get a wonderful view of the organisms as they light up. I think kids would particularly find this fascinating.

  • A must see when at Grand Cayman. Don't take a kayak, take this boat. We'll do it again.

  • I'll try to keep this brief as possible. Our boat had maybe a dozen passengers and the crew: Captain Steve, Debbie, and Alison. Debbie was very nice but clearly was subbing regular personnel and trying to help out. What happened was this: when we dropped anchor, we were supposed to move slowly into the water, a few people at a time. Captain Steve told us to stay on the top of the water as much as possible in order to see the bioluminous effect. The crew was very focused on handing out equipment and it became a little chaotic. Half the people were in the water and half in the boat when the anchor gave way. The boat began to drift and we couldn't see the people in the dark water. Captain Steve began barking orders at Debbie and Alison, it felt out of control. My concern was for the safety of the people in the water, as they might have been hit by the boat or even under it. The situation could have been serious but honestly, it was quickly resolved, but with much disturbance and noise. I mention that because I got in the water after the incident and immediately felt burning all over my body. That's when I understood the real reason the Captain told us to stay on the surface of the water. I, and several others, got stung by jelly fish. All the activity and disturbance brought them to the surface. Here's what I'm mad about: when we emerged from the water, skin on fire, Captain Steve said Oh, yes, that's Sea Itch. It's caused by the very high density of salt in this location. Here, we have some vinegar in this bottle which will fix it right away. First, Sea Itch is a thing, but it has nothing to do with salt, it's jelly fish larvae that get in your clothes and sting you repeatedly. Second, this was just plain old jelly fish stings and rather than admitting that, he insulted our intelligence by making up a lie. I knew something didn't make sense, you don't treat salt with vinegar unless you are a potato chip, but I wasn't sure and I didn't want to cause a scene. Anyway, it was an adventure and it was beautiful, but not letting us know the true nature of risk, lying to us which could be very dangerous if the stings were serious and people didn't seek appropriate care, and barking at the crew made this captain unfit to be responsible for the safety of others. I understand, I probably would not have gone in the water if I'd known it was likely I'd be stung, and probably few others would, and that would ruin the purpose of the tour. I wrote this review because I was the one who booked the tour and I feel like I put my family at risk.

  • Very informative and relaxing tour. You get to see the bioluminous bay and enjoy the scenic sunset and stars on the ride there and back. Highly recommended

  • Super well done. Deb was most personable and shared a lot of information about Cayman Islands and the bioluminescence dinoflagellates. Truly sparkling. Both guides were conscientious about the marine life and environment. Really appreciated that tour was super easy to start from the yatch club.

  • What a magical experience. This was amazing and is a definite must do on a trip to Grand Cayman. The way the water lights up when you swim around is amazing! The only thing this tour would benefit from is a hotel pick up option. However Stephen did take me back to my hotel which was great!

  • This was an awesome tour and I would recommend it to others. Steve and Nikki provided lots of information about the area, culture and the bioluminous creatures. He invited us and the others on the tour to leave a little earlier than scheduled to make a stop at Starfish point which we did. Swimming in the bioluminous waters was very cool and something we will always remember!

  • Excellent trip. Sunset sail followed by a stop at Rum Point, then onto an amazing experience in the bioluminescent bay.

  • This tour was the highlight of our trip to Grand Cayman. My 10 yr old daughter called it the closest thing to magic you actually get to experience and said that she would remember it for the rest of her life. Steve and the crew are incredibly kind and helpful and even pick you up at your hotel. It is a MUST do while in Grand Cayman.

  • Great trip and evening on the water. Viewed from the boat so not as spectacular as being in the water. Slight issue with itching after coming out of water. Staff very professional and nice.
