5.00This was the last night for good visibility at the Bioluminescent bay. George’s was very up front about this and stated that they won’t consider going out for the 2 following weeks when the visibility is not as good. I appreciated their honesty about this and knowing the information up front helped us plan our trip so much better. George’s was responsive, and booking was easy. (George’s had been recommended by a close friend.) The excursion itself was wonderful. The crew had a great sense of humor and attentiveness to everyone. We appreciated the skin suits they provided, and the music was great. Of course the best part was the experience itself. Our family, which includes teen and pre-teen daughters, soaked up every second of being in the water and seeing the dazzling plankton. This is a do not miss experience if you can make it during a time of good visibility. Highly recommend both the tour and using George’s.
Must do!

5.00Snorkeling in the Biolumenscence Bay was a once in a lifetime experience. David and the rest of the crew were wonderful. They offered to take photos with our cell phones and made sure we all had plenty of time in the water. The small group of 15 guests made the experience even better. One family had a toddler who stayed on board with her Grandma. The crew collected some water in a bucket so the toddler could also see the plankton glow and also enjoy the experience. We highly recommend booking this tour with George's Sports early, because it sells out.
Very cool experience to...

5.00Very cool experience to end the day. We were not sure what to expect, but the crew provided all supplies and instructions. They took pictures using our phones, which turned out very well. Highly recommend, especially if you’ve never experienced bioluminescence before!
Definitely don’t skip on this!

5.00This is a bucket list experience! If you have the opportunity, I highly recommend you do it! The staff was friendly and knowledgeable about all the questions we had. We were able to spend plenty of time in the bay swimming and snorkeling around.

5.00George’s Watersports gave us one of the most unforgettable experiences we’ve ever had as a family. From the start, everything felt organized, welcoming, and most importantly—safe. Traveling with kids, that matters a lot, and their crew went above and beyond to make sure we were comfortable every step of the way. The highlight was the bioluminescence tour—and instead of kayaking, we actually got in the water and swam… which made it even more incredible. The moment you move in the water, it lights up around you in this glowing, electric blue—it’s hard to even describe how surreal it feels. Every kick, every splash, even just waving your hands creates this magical shimmer all around your body. It honestly felt like swimming in stars. Seeing the kids’ reactions made it even better—it’s one of those rare experiences where everyone is just in awe at the same time. What really stood out was how safe and well-managed everything was, even while swimming at night. The team stayed close, gave clear guidance, and made sure everyone felt confident in the water. That allowed us to fully relax and just enjoy the moment as a family. If you’re heading to the Cayman Islands, this is a must-do. Swimming in the bioluminescence is something you truly have to experience to believe—it’s magical, unforgettable, and something our family will be talking about for years. 🌊✨
Amazing
