We booked both the Stingray City eco tour and the Bioluminescent Bay tour with George's Watersports for our trip. We had them booked on different days (Friday and Monday) to avoid overcrowding our schedule. Before we arrived on the island, they contacted me to let me know that they had to conduct boat maintenance and had to cancel our tour on Monday. But they handled it as professionally as possible. They rescheduled us for the Bioluminescent Bay tour on Friday night instead and issued us a refund without asking. The bio bay tour itself was fantastic. Swimming clear warm water in the dark with these microscopic organisms is exciting and hard to describe. The boat is new, clean, well maintained (of course), and comfortable. Michael and Val took great care of everyone. They are experienced and take real pride in what they do. George's went out of their way to make our experience memorable. I'd book with them again without hesitation.
Thank you for doing the bioluminescence snorkel tour with us, we're glad that you enjoyed the experience and we hope to see you again next time you visit Grand Cayman!
I went with my 2 daughters ages 18 and 14 we had a great time, Tour was on time. Boat had water/soda. we were given wet suits to protect against jelly fish and noodles to help us float so feet didnt touch to disturb jelly fish. water was 5 - 6" deep. the experience was great. in the water they told us diff things to do for diff effects. they also took our phones to take pictures but some phones are better than others. It was expensive but worth it. How many chances do you get to see something like this. Tour operators were great, friendly, gave us all the instructions we needed and we felt safe in the water and that they were watching. Location was easy to find and plenty of parking. we used this same company for the stingrays and we were not disappointed with either
Thank you for doing our bioluminescence snorkel tour in the Bio Bay, we're glad that you had a great experience, and we hope to see you next time you visit Grand Cayman!
Quite an amazing tour experience. The bioluminescent organisms are very bright under the water. If you've been to the bio bay in Vieques, Puerto Rico, this is very different. It's going to be worth the trip. You'll be swimming in the glowing sea. The glow is right in your face and at your finger tips. The water is warm, clean and still. The tour was very well organized. Get on the roof of the boat if you're not afraid of height.
This is a must do! I was a little skeptical, wasn’t sure what to expect. The pictures you see online don’t do it justice, it was an amazing experience. The boat is new and very comfortable, the 2 crew members were friendly and helpful. It’s a 2 hour total trip with about 40 minutes in the water. At first we thought that was too long, but it flew by and we could have spent so much longer enjoying it. Don’t do a kayak only trip, you must get in the water and snorkel. It’s simple, easy and completely safe. One of our best ever excursions and experience.
Thank you for the review, we appreciate it!
Great experience in Cayman Islands with great crew - really enjoyed it.
Thank you for doing our bioluminescence snorkel tour in the Bioluminescent Bay, we hope to see you again next time you visit Grand Cayman!
This is a very cool experience. The boat ride out to the cove was fun and then you experience the bio lighting up.
Absolutely loved it! They were very professional, friendly, and knowledgeable about what they do. The boat ride out to the bay was an extra bonus. Highly recommend.
The excursion was for two hours but the first hour was just to pick up other people and make time until night. When we actually got there, we were expecting something more spectacular, but it is a different experience, for sure. Anyway, it was a nice night boat ride.
Thank you for doing our bioluminescence snorkel tour, we appreciate it! The concentration of the plankton in the Bio Bay can vary frm week to week, since factors like tide, wind direction and weather impacts it. We hope to see you again next time you visit the island!
THE BEST thing we did in Grand Cayman. A once in a lifetime experience. I am so glad we got to experience this.
