Experience a truly out-of-this-world experience in the summer months of the Space Coast. From June to October, the waters of the Indian, Banana, and Mosquito Lagoon come alive with one of the world’s natural phenomena.
Every year, visitors worldwide see pulsing Comb Jellies and glittering dinoflagellates that create mystical light shows. While its function isn’t known for all animals, bioluminescence is typically used to evade or warn predators.
Visitors embark on an inexplicable experience on kayak excursions from many guided bioluminescence tours on the Florida coast. Waters come alive with bioluminescence, shining like stars in the night.
Florida has many beautiful places where visitors can see glowing algae and other sea creatures, including the Banana River and the Indian River, also known as Florida’s “Bioluminescent Bay.”
Some popular places visitors can see bioluminescence in Florida include:
Bioluminescence is the light produced by a chemical reaction in living organisms. While relatively rare on land, it’s a very common phenomenon in the ocean. Every stroke of the puddle and move made by the mullet and manatees below the surface shows a mesmerizing spectacle that can only be experienced in a few places worldwide.
Bioluminescence season typically begins in late May or June. However, July and September are usually the peak of the bioluminescence season. We encourage visitors to book a tour with A Day Away Kayak Tours during a new moon, which amplifies the shimmering stars and glittering water. Other factors that may affect bioluminescence glow are rain and storms. Our guides will always do their best to take visitors to where it’s most brilliant.
Bioluminescence only occurs in animal species that contain luciferin. Depending on the animal, this molecule produces greenish-blue light when it reacts to oxygen. Some organisms produce luciferase, which catalyzes luciferin oxidation, causing them to glow.
Interestingly, some animals can control when they light up and glow by regulating their brain and chemistry. Bioluminescent animals do this depending on their immediate needs, such as eating or mating.
Many marine organisms are bioluminescent, including bacteria, algae, jellyfish, sea stars, worms, fish, sharks, and crustaceans. Some animals also ingest bacteria and other bioluminescent organisms, allowing them to light up and glow.
Dinoflagellates are single-celled organisms found in rivers, streams, freshwater ponds, and oceans. They’re commonly called algae and have nearly 2,000 recorded living species. What makes dinoflagellates remarkable is that they can glow in the dark.
These interesting facts about dinoflagellates will astound even the avid adventurers:
Because moonlight affects how visitors can see the glowing bioluminescent plankton and other luminous sea creatures, we recommend picking a pitch-dark night with as little moonlight as possible or no moon (no glare of the moon on the water’s surface).
The best seasons to book a bioluminescent kayaking tour are May and September. July and August are often the peak seasons for kayaking, as dinoflagellates also appear bright every night. October to April is Glowing Jellies season. There’s nothing more awe-inspiring than when nature is stranger than fiction.
A Day Away Kayak Tours offers nature’s safest and most enchanting bioluminescent experience, no wishing required. We select the best tour times that coincide with the peak of bioluminescence, ensuring every customer gets the most out of their adventure.
Comb jellies are oval-shaped creatures that get their name from comb-like plates they use to propel themselves in water. These plates diffract and reflect light, giving a shimmering effect. They’re a spectacle for many visitors kayaking in Cocoa Beach, Florida.
However, many people don’t know much about Comb Jellies; some have never heard of it. Here are some fun facts about these amazing creatures to keep in mind:

EXCELLENT Based on 10 reviews Gergely Halász2025-06-02Trustindex verifies that the original source of the review is Google. Fantastic experience. (Bioluminescence night kayaking) Wonderful tour guide, with entertaining fun facts and real care for safety. Even after 7 night cruise, this was the highlight of our journey. Literally to touch nature as your hands and paddles sparkles diamonds in the night water. Paddling next to sleeping manatees. If you have a free night in this area and you don’t mind getting bit wet you must try this! Ashley Corcoran - West2025-05-30Trustindex verifies that the original source of the review is Google. This was such an awesome experience!! It rained so we were a little delayed but weather cleared in time to do the tour by about 10:30 pm. Matthew was extremely friendly and a VERY knowledgeable guide. We saw so much bioluminescense. The bioluminescent jellies were beautiful! I even finally caught one! I 100% will do this again!!! Lisa Loo2025-05-25Trustindex verifies that the original source of the review is Google. What a fun and memorable experience! Drew & Jorge were the best guides and the entire trip was fun, informative, calming and simply perfection. Jill Connolly2025-02-04Trustindex verifies that the original source of the review is Google. We had a great time kayaking and experienced the comb jellies during the bioluminescence tour. Aiden was very knowledgeable and friendly! Would highly recommend. Easy to find based on instructions provided Helen B2024-12-21Trustindex verifies that the original source of the review is Google. We had a great tour last night. Wish a many many manatees, many dolphins and alligator tons of cum jellies even a little bioluminescent phytoplankton. Our guide Gabe was delightful. A very young man but incredibly knowledgeable well spoken, friendly and helpful.a the launch area was out in a national preserve with dirt roads and unreliable GPS. So make sure you know where you’re going before you get to the preserve and lose GPS signal. Cole Wong2024-11-29Trustindex verifies that the original source of the review is Google. Our tour guide Amy was knowledgeable with finding good spots to see bioluminescence. Make sure to book your tour on warmer days to increase your chances. It's also more common in the summer but we were able to catch it in late November especially with no moon. FYI the building is the one with a blue rooftop and amongst the grass. Might be hard to spot at night. Adél S (ChuckNorris28)2024-11-15Trustindex verifies that the original source of the review is Google. I booked a tour with my girlfriend to see bioluminescence. The house wasn't easy to find in the dark, but some candles helped. It also turned out we were the only ones who booked this tour - and yet it still wasn't cancelled. Our guide, her name was Madison, was very welcoming and open-hearted. She basically made an exclusive tour for us. We got life jackets and a short introduction how to paddle and how to react in possible incidents. We did another kayak tour couple of days before in Crystal river and didn't get any of this. However, due to unsettled water we couldn't get to the better parts of Banana river to see bio, and light pollution and moon shining basically eliminated any chances to see it anyways. We still had a great time with Madison and had fun chatting with a local and learn about Florida, especially since we are from Germany. I would recommend this tour, but pay attention to moon phases. It's also easier to see bio in warmer months (May to August). Island2024-09-29Trustindex verifies that the original source of the review is Google. I went a couple months ago tour was amazing saw lots of bio.
