Grand Cayman Bioluminescent Bay Tours
We offer the most exciting and convenient bioluminescence tour in the Cayman Islands. Our tour departs from the Cayman Islands Yacht Club, which is a 5 minute drive from Seven Mile Beach and saves you over an hour journey driving to North Side.
The visibility of the bioluminescence is literally 10x better when viewed in the water with a mask. Most people think that the kayak tour is more interactive, but this couldn’t be further from the truth. Only on the boat tour do you have the option to go into the water with a snorkel and mask. If you stay on the boat, the visibility of the bioluminescence is the exact same as if you were on a kayak, but when you are in the water with a mask, it is a whole different level. The water is only 4 feet deep, they are no sharks, it is not cold, there are no waves/currents, and we have life jackets.

Our tour is on a comfortable 30 foot boat, which can hold up to 12 people. We limit the tour size to allow people to have a more enjoyable and peaceful experience. The boat is a modern speed boat, which is frequently maintained and safe for your friends and family. We offer optional life vests for everyone, in particular for children while we are on the boat. We depart from the Yacht Club and cruise to the Bio Bay where it is possible to see it. The boat is very comfortable with padded seats and space. We offer complementary drinks during the trip with ice so that everyone can stay hydrated. The boat trip takes approximately 20 minutes each way and then we allow everyone to have a sufficient time swimming in the bay before we return to the Yacht Club. The sea is warm all year round and we provide towels at the end so that people can dry off before they head back to their hotel.
This phenomenon is caused by millions of tiny single-celled organisms known as “dinoflagellates”. Movement of the dinoflagellates caused by your hand, body, or the boat results in the whole bay erupting in bright light. We offer the opportunity for people on the tour to swim in the bay to enhance the experience. With a snorkel and mask one can see the plankton very clearly and it is like swimming through the stars in the night sky. The dinoflagellates light up like millions of diamonds and contrasting this sight with the darkness of the water makes our tour an unforgettable experience. This tour is enjoyable for everyone and we offer complimentary life vests and wet suits. For those who are not comfortable swimmers, it is possible to see the gentle glow from the boat when everyone else swims in the water. There is no danger swimming at night because the bay is sheltered from the barrier reef and the water is only 15 foot deep.
It is not possible to experience this spectacle everywhere on Grand Cayman, therefore one needs to take a tour to arrive at the Bio Bay. The bay is shallow and sheltered, which makes it the perfect habitat for dinoflagellates. These plankton are not dangerous and you cannot feel them when you swim with them. The extraordinary light which they produce can seen perfectly when there is little or no moon in the sky. Therefore, our tour is dependent on the moon and the weather, so we can avoid light pollution and see the phenomenon well throughout the tour.
Another benefit of this tour is that you will have the opportunity to gaze at the stunning night sky and absorb the beauty of the stars. The stunning contrast of the view of the stars from Grand Cayman, which is away from city lights compared to larger metropolis areas is truly remarkable. If you are lucky, you may also be able to make a wish on a shooting star. It is incredible to experience the sensation of swimming through the sparkles, which is like swimming through the stars, and then looking up and seeing the stunning stars above you.
The location of our tour makes it unrivaled in convenience and offers the best value for money, on top of great customer service. During our Grand Cayman bioluminescence tour, our crew enjoys sharing their wisdom about the island. We can collect you from your hotel or condo and take you to the docks and this service is complimentary to the tour. Other companies on island, do not provide this free pick up service and are not located at a convenient location from Seven Mile Beach, thus making our tour the best option. Our primary aim is to provide a quality service and enrich everyone’s understanding of the Cayman Islands ecosystem, while having a fantastic experience on the water.
Seeing this is a once in a lifetime opportunity and not many people have been fortunate enough to see this amazing phenomenon. This activity is perfect for family and friends who want to do something safe, accessible to everyone and unforgettable. There is nothing more exhilarating then swimming at night through millions of bright sparkles and this activity is consistently viewed as one of the top must do activities in Grand Cayman.
