After Check-in guides gather group for a brief session covering basic kayaking, rules of the road, and the importance of keeping a minimum disturbance of the environment of the bioluminescent lagoon. Then we launch our kayaks and head for a hidden opening in the mangroves in northern end of the beach. Upon entering the mangroves, we follow a channel for a mile leading to Laguna Grande. Once we enter the laguna your guides gather group for an informative talk about: This unique ecosystem, the flora, fauna, and sea life that inhabits the lagoon, and historical notes. Our bay is very delicate as it depends on the ecosystem surrounding it. Due to climate changes and other factors the bioluminescent bay can reduce its fluorescent lights . This means that the glow is not guaranteed . This all depends on natural or human causes that can affect the organisms. Our company is not responsible for these changes as we do our best to provide a unique experience for all who visit the island.

This tour was a disappointment. Our tour guides were not very engaging or knowledgable. The only way to see the bioluminescence was to have a tarp draped over you and to stir the water around with your hands. You could barely see any. I do not recommend this tour- if you really want to see them, chose a different tour on the island. Or better yet, go to Mosquito Bay were they are see much better.

DISREGARD ANY GOOD REVIEW - I genuinely do not understand how anyone has had a good, or safe, experience on this tour. Upon arrival, we smelled the wretched Lagoon water before we even pulled into the parking lot. Little did we know, we would be sitting in a small puddle of this wretched sludge in the seat of our kayak throughout the entire tour. (Ladies, bring a change of bottoms). The kayak experience was incredibly arduous and dangerous, taking place in the pitch darkness, through narrow mangrove tunnels, and little to no guidance. (A suggestion for future tours would be to give a flashlight to each kayak! It was very hard to navigate and see the way in the darkness.) Many crashes took place along the way. I deeply feared for my safety, and the safety of others. It was clear the rest of the group felt that way as well, due to the screaming. As we made our way into the middle of the lagoon, we were not able to see any bioluminescence. It was incredibly underwhelming, and we felt like we had struggled to get there for nothing. The stars were beautiful to look at, I must say! That was the highlight. The guides were very, very nice, and informative, and I do not want to blame them. I think they did a great job with what they had, I just think the overall experience was not a safe one. When we got to our final destination, we were lined up kayak to kayak and given a very large, disgusting, putrid, possibly moldy tarp to drape over everyone. We were told to put our arms into the water, swish it around, and look for traces of bioluminescence on our hands. I felt like someone was playing a sick joke on us. We all just looked at each other in confusion, disappointment, and complete, utter shock. Because what the hell was that? No bioluminescence. And, where were we supposed to dip our hands when we were shoved kayak to kayak? It was brutal and senseless. After we couldn't see the bioluminescence, the guides let us paddle around freely for a short bit of time without any directions on how to return to them, and after a short while of being left to our own devices, many people in the group, my friend and I included, began to panic because we did not know where our guides were or how to return to them or when we could expect to head back. We even called out their names to try to find them, and didn't receive a response. It was very scary. On the way back, there were tarpon splashing in the pitch black darkness, and kayakers were visibly panicked. The kayak back felt long and challenging, and defeating. Overall, I would not recommend this experience. Unless you find it pleasurable to endure trials and tribulations while feeling mildly humiliated and slightly insane. It felt more like a social experiment than an experience. I can not believe I paid for this. It was not a laid back, enjoyable experience. It felt really unsafe and scary and difficult, with seemingly no reward.

Guides put up with my group’s antics and made it fun and educational despite diminishing phytoplankton populations

After going on the Eco Adventures bioluminescent kayaking tour in Fajardo, I feel compelled to warn others—not just about the underwhelming bioluminescence, but about the serious safety concerns that overshadowed the entire experience. This tour takes place in complete darkness, through a very narrow, heavily crowded mangrove tunnel, without any maps, lighting, or clear directional guidance. While the company emphasizes that the darkness is necessary to see the glow, the logistics of the experience were reckless at best. On our return trip, another large group from a separate tour company was entering the tunnel at the same time—coming with the current, at a much faster pace, in the opposite direction. What followed was pure chaos. My husband and I were hit multiple times by other kayakers, many of whom were inexperienced and visibly panicked. There appeared to be no coordination between companies to ensure that one group passed safely before the other entered. This lack of basic communication created an incredibly dangerous and stressful bottleneck. Guests were colliding with each other, scraping against branches, and shouting instructions in the dark with little support from guides who were trying their best to manage the confusion. Despite the company’s claim that this is an “immersive, nature-based tour,” that should not excuse poor planning or a lack of safety protocols. Allowing large numbers of inexperienced kayakers to navigate tight, pitch-black tunnels without structured group management is not immersive—it’s irresponsible. If nature is the draw, then tour operators should respect it enough to limit traffic, reduce overlap between groups, and make the experience safer for everyone. Also worth noting: when customers express disappointment, the company’s response is not to empathize, but to defend themselves. That in itself says a lot. Rather than acknowledging genuine concerns, they double down and imply that guests just didn’t read the fine print. That’s not accountability—it’s deflection. To be clear, the guides were wonderful and clearly doing their best. This review is not about them—it’s about a system that prioritizes volume over safety, and vague disclaimers over transparency. If you’re considering this tour, I urge you to think twice. It’s not just a disappointing experience—it’s a potentially dangerous one. The risks are real, and frankly, not worth the price or the stress.

What a wonderful experience! The company was great to work with for a last minute reservation. I liked that this company takes out smaller groups - which makes the tour more personalized. Safety was a priority for the guides, as well as providing detailed knowledge. I highly recommend (also worth doing right to their site to book).

Me and my daughter were having a hard time as it was our first time. The staff was very helpful and made sure to guide us the whole way through. It was an amazing experience.

This was a really fun night kayak trip and our guide, Chris, was very personable, gave lots of little bits of information, and we loved the tarp strategy to be able to see the glowing dinoflagellates better!!! My partner had been on a different tour years go and they did not do the tarp trick, so this was something that intensified the experience, especially if you don't go on a good night or there is too much light pollution, or they just aren't very bright. The only thing that was not awesome about the trip was that some of the slower, less experienced kayakers did bump into other kayaks and I think it would have been helpful if the tour guide had more experienced kayakers in the front and less experienced in the back to have a little more attention and space.

Experience was great, definitely a little more challenging than I expected but not that bad. Was a lot of fun and the tour guides were very knowledgeable. Most everything was smooth, the only problems were disruptive actions of other participants and parents not controlling their kids - nothing at the fault of the tour company. This basically just made everything take a bit longer so in the long run it was not too bad. Overall the tour company did a great job and I’d recommend this to everyone going to PR.

Oswaldo was great with us, the kayaking part is not that easy and it can be frustrating and stressful. However we did have the support and guidance from the three guides that went with us. Glowing was very subtle, not a good night apparently but they did their best effort to show us the best of it. One complaint that I have is that the guy that makes the check in part is unkind and unfriendly. Sadly, he is the face of the company and the first point of contact. This is a once in a life experience for me, would not be willing to go back at all.
