The Bio Bay trip includes all essential safety equipment, specialized gear, professional guides, water, light snacks, insect repellent, basic kayak lessons, a safety briefing, and plenty of fun! Bring extra clothing and a towel as you are likely to get wet. We will paddle through a mangrove-lined canal, approximately 1 mile long, to reach the bioluminescent lagoon.

For safety reasons, pregnant women cannot participate. (NO EXCEPTIONS)
Our kayaks are tandem kayaks for two people – you are booking per person, not per kayak. If one space is available, it means there is 1 spot on a tandem kayak.
Guests under 18 years of age must be accompanied by an adult.
The owner of a service animal must provide a Coast Guard-licensed life vest for the animal. The animal must be under complete control at all times. Be aware that there will be many people around in the dark.
Guests unable to complete the tour for any reason will not receive any type of refund.
All guests must be able to row their kayaks independently. A requirement is that you can get in and out of the kayak on your own and maneuver it. If you are an inexperienced kayaker, we highly recommend choosing the earlier tour.
If one space is available, it means there is 1 spot (for 1 person) on a tandem kayak (no single kayaks available). You will be paired with another guest on the tour.
All guests must arrive 30 minutes before the start of their tour. We respectfully will not accept or wait for any guest after this time.
If necessary, a tarp (canopy) may be used during the excursion to block light pollution and enhance the experience.
To best appreciate the bioluminescent phenomenon, our tours take place at sunset and early evening. It can get quite dark in the mangrove canal. Therefore, if you are afraid of the dark, a first-time kayaker, or have small children, we strongly suggest taking the earlier, sunset trip. This allows you to see where you are going, acclimate to the environment, and practice your kayaking skills.
Due to the immense popularity of the Bio Bay tour, it can sometimes get crowded. It is not uncommon to encounter other tour groups waiting to access the canal leading to the lagoon. Kayaks may bump into each other along the way.
Please keep in mind that this tour takes place in a natural environment, and while rare, the bioluminescent phenomenon can be observed year-round. The intensity of the glow is unpredictable and can vary suddenly from minimal to very bright.
SPECIAL NOTE: We encourage guests not to book the tour on their arrival day to the island, including travel from Vieques or Culebra. If a flight or ferry is delayed and the guest misses the tour, they will not be entitled to a refund or rescheduling.
TOUR TIMES may change depending on sunset time. If so, we will send a reminder with the updated meeting time.
This tour takes place in the water. Expect to get completely wet. Wear clothes and shoes that can get wet. We recommend bringing a change of clothes and a towel for after the trip.
The tour is not canceled on rainy days. We will get wet anyway ;)
Public restrooms are available on-site, but their condition may vary. Consider stopping at a fast-food restaurant before reaching the meeting site or using restrooms at nearby stores/restaurants, which are sometimes available.
Certain times of the year, large amounts of sargassum (seaweed) arrive on our coasts. This can make paddling feel like a workout. Additionally, the natural decomposition odor might be unpleasant.
Even if the Viator system allows guests to enter a weight over the limit, the weight limit remains 240 lbs.
No expecting mothers allowed.
For safety reasons, children under 6 years old CANNOT participate in the PURE ADVENTURE tour.
Individuals with epilepsy, back problems, claustrophobia, heart conditions, dizziness, recent surgery, or any other condition that could pose a risk to life are not permitted to participate in the PURE ADVENTURE tour.

I think 3 stars is...
Kristina_S, September 2026
I think 3 stars is generous! The guides were great and very knowledgeable. Aside from that, I’m not sure I would do this again or recommend it to others. We saw little to no bioluminescence. The experience looks NOTHING like the pictures! Overall, I feel like we got ripped off!
Response from the operator · PAowner
Hello Kristina_S, Thank you for sharing your feedback. We’re glad to hear that you enjoyed our guides and appreciated their knowledge and professionalism. We’re sorry the bioluminescence was not as visible as you had hoped. We completely understand how disappointing that can be, especially when you’re looking forward to seeing the glowing water. It’s important to note, however, that bioluminescence is a natural phenomenon, and its intensity can vary significantly and sometimes change unexpectedly—even from one night to the next. Unlike a show or attraction, we cannot control or guarantee how much bioluminescence will be visible during a particular tour. The photos commonly used to showcase bioluminescence capture exceptional conditions and are not necessarily representative of every night. We always want our guests to have a memorable experience, and we’re sorry that the conditions during your visit did not meet your expectations. We truly appreciate your kind words about our guides and hope you’ll consider giving us another opportunity to share the magic of Puerto Rico’s natural wonders with you. Cordially, Yolanda Ramos PURE ADVENTURE

Unique experience
Cherayl_P, September 2026
All the guys who took us out on this tour were amazing, especially Javier! We had a couple in our group who were having a tough time navigating the operation of a tandem kayak and Javier was right there to help make sure they made it back swiftly with the rest of the group. We stopped in the lagoon and one of the guys was pointing out star constellations, while others looked at the bioluminescence. Since the moon illuminated, nearly full, We used a canopy to see the bioluminescence but it was still very cool! I would recommend going on a new moon and to make sure you will be comfortable kayaking in the dark. It’s not hard, but Communication and coordination are key in navigating the waterways with your partner on this trip. Thank you to all the guys for your expertise, sense of humor, and especially Javier for helping our group!

Dear Cherayl_P, Thank you so much for your thoughtful review! We’re delighted to hear that you enjoyed the experience and that our guides made you feel supported throughout the tour. We’ll be sure to share your kind words with Javier and the entire team. We truly appreciate your recommendation and hope to welcome you back for another unforgettable night under the stars! Cordially, Yolanda Ramos PURE ADVENTURE

Amazing Experience!
erikhN3454BJ, September 2026
We had an amazing experience with Eli, Javier and Natalia during our 6pm bio bay tour. We were so happy we did this tour and will remember it forever! The mangroves were so tranquil and the bay was beautiful, Javier did a great job explaining the stars at night and Eli kept us all entertained while paddling. Ten stars out of five! -Erik, Mariella, and Robyn
