5.00The bioluminescence tour was one of the best activities of the entire trip. Truly magical. The crew was friendly and organized. Pictures don't do the experience justice...my favorite was seeing the glow underwater. The ride to the site was smooth. They provided snorkels/masks and wet suits to protect against the jellyfish. I also liked how the suits were dark so didn't take away from the luminescence. Bring a black/dark wetsuit if bringing your own. Water and sodas were also included. 100% recommend this tour with this company.
Excellent experience

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.
