A private tour is the way to go! There was 4 of us and we had a wonderful time with Jordan. This was the highlight of our trip!! Highly recommend and we would definitely book with them again.





There are only a handful of bioluminescence or bioluminescent bays in the Caribbean, and not many more than that in the world. They only occur in certain places because they only happen naturally under very specific conditions. The water in Bio Bay is very warm and salty with an abundance of nutrients and seagrass, the perfect environment for special microscopic plankton. These plankton occur all over the island, and all over the Caribbean, but the concentration we find in Bio Bay is what makes for a fantastic experience. Because of these plankton “bioluminescence,” it produces a very short burst of light when stimulated by movement. The Bio Bay is best viewed by floating in the water. With snorkeling gear, you’ll float in this magical bay mesmerized as your movements create trails of light in the water. This shimmering light show is awesome, and if the timing and conditions are right, you might even see the mating glow worms which occur two to three days after the full moon.

Such an amazing experience! One of the main highlights of our trip for our kids. The pictures can’t do it justice. The boat ride itself was enjoyable as well. Would definitely recommend!
It was fantastic. We went with a five year-old and were a little worried when we booked it. Turns out she did great. The snorkeling was great. She had a life vest and was able to stay close to me. The whole family loved the stingrays and we got great pics with the starfish. I would highly recommend going with Captain Charles.
The Bio tour was great! Highly recommend! The weather was bad the night we were supposed to go and they kindly moved us to the next night!
This experience was amazing. Jordan was the very best guide! He was wonderful with our 3 kids under 5 and told us all about the area. The boat ride was so much fun, we cranked up “Under the Sea” and “I am Moans” on the Bluetooth. We saw the beautiful sunset from the boat ! We were amazed at the Bioluminescent Bay and the water show from the plankton. The 3 year old made the glowing water shoot out like Elsa did in the movie Frozen. Our son really got the water glowing with his fast movements..This was a sight everyone show see and this is the company to trust!! Thanks Jordan!!
Very nice experience! I would highly recommend
Amazing way to see the bioluminescent bay in small, modern and lovely boat. So few of these bays in the world and the ability to snorkel at night and see the luminescence was amazing. Justin, our captain, was kind and knowledgeable. Definitely recommend!
Our whole group loved this excursion! Our captain Jordan was informative and kind (we had 4 children in our group) and we loved the bioluminescence experience! Would definitely recommend the private tour, our group of 8 was very happy.
Great tour and boat ride. Jordan was informative and very helpful with the kids. The family had a wonderful time.
Thank you for your feedback! So happy you enjoyed the trip!!
We are a group of 4, on a girls trip. We looked at all the options for the bioluminescent bay tour but most were very expensive just to be on a large crowded boat. The 4 of us were able to book a beautiful and private charter boat with an awesome tour guide and split the overall cost for the same as we would have individually paid with other group charters. The experience was a once in a lifetime and worth every penny. The bioluminescence was so bright and beautiful! I highly recommend this tour. I will be bringing my whole family back to see this and will most definitely use this company again!
Thank you so much for sharing your feedback. We are so happy to hear you enjoyed your experience with us. We look forward to hosting you again in the future!
