• 5A unique experience with an amazing crew!

  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.

• 5Amazing experience

  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

• 5Swimming in glowing sea

  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.

• 5An absolute amazing experience

  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.

About Grand Cayman

Grand Cayman is the largest of the three Cayman Islands, a flat Caribbean island known for Seven Mile Beach, coral reefs and shallow sandbar waters.

George Town, the capital, sits on the sheltered west coast of Grand Cayman, a low limestone island ringed by coral. Seven Mile Beach, a long band of pale sand running north from the capital, is lined with hotels, restaurants and dive shops. The Cayman Islands are a British Overseas Territory, and the banking offices of George Town stand beside the cruise piers and the small national museum.
