✨ Bioluminescence & Natural Conditions Disclaimer

The bioluminescent glow is a natural phenomenon and its intensity varies daily due to environmental conditions beyond our control. Factors such as rainfall, tides, moon phases and brightness, cloud cover, water temperature, seasonal changes, sargassum, water clarity, and other natural events may affect the visibility and brightness of the glow.

While our tour is commonly known as a "Bio Bay Night Kayak Tour," the experience is designed to offer much more than the bioluminescence itself. Guests will enjoy a guided nighttime adventure featuring the peaceful atmosphere of the lagoon, the surrounding ecosystem, the night sky, and the unique experience of kayaking in Puerto Rico after dark.

Because bioluminescence is a naturally occurring phenomenon, we cannot guarantee the intensity of the glow or that it will be visible during your visit. In certain conditions, our guides may provide tarps or other light-blocking materials to help guests better observe any available glow by reducing surrounding light pollution. However, the use of these materials does not guarantee visibility of the bioluminescence.

By choosing to participate in the tour, guests acknowledge and accept that glow intensity may vary or be absent due to natural causes. If the tour operates as scheduled and guests choose to participate, refunds, credits, rescheduling, or compensation will not be provided due to low or absent bioluminescence visibility.

We appreciate your understanding and look forward to sharing this beautiful natural environment and unforgettable nighttime adventure with you.

Since we are not the only operators in this area, there may be more participants in the bay then the maximum number of participants we take per schedule.

    Truly a fun experience! Felix, Onyx, and Emmanuel did such a good job!! Not only did they told us how to kayak but we even got to see of the Bioluminescence in the off season!

  • Don’t do unless you’ve done some homework.

    Be informed, April is worst month for bioluminescence. Wish we were told that ahead of time. We arrived at 5:15 as requested time for a 6:00-8:00 activity. No one was there until 6:05. Then we were told it would start at 6:30. The whole place reeked of rotting seaweed which suffocates the organisms and greatly reduces the bioluminescence. Guide was a nice guy but safety instructions and their photos were taken alongside the rotting seaweed. I was gonna gag. There are warnings about toxic effects of sunscreen and bug spray to the organisms but we were waded out to the kayaks washing off our bug spray and sunscreen into the water. Kayak experience was fun and interesting especially in the dark if you’re up for that. You will get wet, and dirty and DO NOT wear nice sneakers but good water/reef shoes. We saw virtually NO bioluminescence at all. I mean zero and that was after they dropped a wet smelly tarp over us to try to darken things even more. Didn’t help one bit. Will try this again some other time but not near Fajardo and certainly not in March-May.

  • Wear a bathing suit

    You will walk into stinky water, it may be as deep as or deeper than your waist. Plan accordingly. If you do the 8pm tour there is no lighting (although a passing tour guide may temporarily light the way),and you will be navigating under mangrove trees through current. There is two way traffic including kayaks and motor boats, while through narrow passage. Make sure you can paddle 3 miles, have great communication with your partner! You will be smacked by other kayakers, you will get pushed into mangroves and you may get injured. The bioluminescence was significantly over-dated and huddling under a tarp was wet and slightly gross. Although we had a good laugh, we were lucky to have had a change of clothes and good spirits. I would probably have given a better rating had, at any point, someone said that the way into the kayaks was as deep as it was. Granted we could have arrived wearing suits, most folk in our group (of 30, not 12 like the site says there will be) did not and the general consensus was shock and minor upset.

    Amazing, fun and exciting experience. An exciting activity in the dark, plus a challenge of synchronicity and strength.

  • Ok trip but bioluminescence was underwhelming

    We did this trip yesterday and I have to say the bioluminescence was rather underwhelming. The photos made it look like we would see it while paddling. They had us put a giant tarp over our heads in order to see it. The kayaking was fun, but definitely need to be able to do 3 miles. Also, they said they would post pictures of everyone. The photos they posted were very blurry, my family has a good laugh at them after the long night. I would say our guides did a good job.

    Fantastic time and such a different experience. Guides were excellent and we had a great time. Wonderful moments and memories with my daughter.

    This can be a great adventure, but there are some things that would have been helpful to manage expectations. We did the 8:00 pm tour in mid March. I thought the kayaks through mangroves was a great adventure! The others in my group felt unsafe as you genuinely could not tell if you were headed straight into the hard mangroves or were going to get your eye poked. My 8 year old cried a lot. This tour company had friendly guides. This tour company also had the most notably dim lights (others kayaks were much brighter and well marked). The dim lights on our kayaks made it more challenging to keep tabs on kayaks in front of you and awareness of where sides of mangroves were. The bioluminescence was what I was most excited about for my kids to see. (Ages 17,15,13,8). It was neat and the bay itself was beautiful. But the bioluminescence didn’t look anything like the pictures. If you know that ahead of time, you can avoid disappointment. It looked like bubbles in a pool with a light on at night. Also, the tarps they use to try and make it darker were damp and sandy and did not enhance the experience. The stars the guides pointed out in bay were the best part. We enjoyed that! One more note - the directions say to wear something that could get wet. It did not specify that you are walking in waste deep water to reach the kayaks. Had I known that - I could have better prepared my youngest. It was a little spooky. Choppy ocean water at night and you start off the ride soaked from waste down. Again - not a deal breaker but could have helped manage expectations.

  • Fun, but not for everyone.

    It was a great tour. This is not for all experience levels even though it’s advertised that way. Other than that it’s a great adventure.

    Unfortunately your lead instructor did a terrible job keeping our party together. As you know this trip has had its challenges. He easily could have kept my daughter 16 and my wife with my boat who was put with another single rider. I’m not a complainer but I do speak up when efforts are not made to accommodate a paying customer.

  • Good Time!

    The guides were great! Lots of fun. Need to be in good shape to kayak through the mangroves. Everyone throws a big tarp over their heads to really see the bioluminescence because the light pollution from Fajardo makes it hard, but we also saw some as we were kayaking back.
