Bioluminescent Bay Fajardo with the Glass Bottom Tour adventure group…read more Now I can put a check mark on something which claims to be only in 5 locations in the entire world, Puerto Rico boasting of 3 of them- the bioluminescent bay Point 1- and most important point: You should have at least a little bit of kayaking experience, good enough to know steering, its not a mandate no, but if u don't then U will definitely fall way behind the others. Point 2- You Will get wet. Wear clothes you are ok to wet. Don't carry anything important on you which you mind getting wet. There may be mosquitoes time to time, be mentally prepared. You will be knee deep in water, wear appropriate shoes, but you can leave the shoes in the car and go barefoot. Point 3- The darker the night, the better the luminescence. Note: In a certain area, the water illuminates when you dip your hand or anything else in it. Swimming is prohibited there but hands, legs, peddles are all ok. Thats what it is. And to think its all because of a certain plankton, a natural phenomenon, is what makes it all that special. A starlit sky above, a huge expanse of water in the dark where u can only hear one another, your kayaking partner beside you, your team with you, all kayaking, laughing, listening to the night sounds, or catching sight of a sleepy iguana- all these make it a fun experience. And gosh the guides ! They are so helpful and absolutely hilarious, all the while being motivated... if I completed anything and made it through, it was only because of them. Yes, it all exciting, adventurous and fun, but if in your head you have built up a magically lit pond (which, i had), then NO its not that at all. I want to stress on this again - the guides were absolutely wonderful people. They make sure everyone enjoy and keep the whole experience interactive while making sure all the precautions are followed. And if I can put a check mark its only because of they not giving up on us, and they waited, helped and made us not miss the experience however late we were.

He kept yelling at us over and over to follow him as he was dead stopped in the water and he was flush with the group. We went back and forth between being told to speed up or slow down and spent a lot of time just floating rather than kayaking. We were unable to see him at all and all of the yelling was very stressful, I wish we could have just had a dim light to follow like other tours offer. We were supposed to kayak for an hour according to the description but were out of the water by 8:30 and didn't even enter the water until after 7:50. And before you ask, no one was late so we didn't start late. We spent more time rafted together talking about the stars and the constellations than we did enjoying the dinoflagellates. For reference, I have been coming to mosquito bay every few years for nearly 25 years. I have never felt more rushed like cattle and unable to appreciate the beauty of the bay. Additionally we overheard the guides talking about various members of the group behind their backs afterwards. I speak Spanish and heard it all-- never appropriate to do this in front of customers no matter the situation. One other guest within earshot heard them saying the things above and commented to me about it as she could also understand them. Also overheard one joking with another about how they're essentially here for the money grab. Unfortunately I think that his phrase is the best way to sum up the vibes of our tour. Adding a star because the bay is amazing. Even though it's not as bright after Maria it's still such an amazing piece of nature.

I recommend wearing water shoes as you'll have to walk through thigh deep water to get to the kayak. You want to plan your trip as close to a new moon as possible as you want to eliminate as much light as possible to really see the glow. Annoyingly there is a neighborhood above the lagoon with bright spotlights but facing the water way and lingering near the other side of the lagoon the bioluminescence is still very visible and a total blast. The guides even brought us a tiny jellyfish to observe and see how it glowed as it wiggled in our hands. I wouldn't even bother bringing your phone, I highly doubt you'd be able to capture the glow while holding still enough in a kayak. Navigating the mangroves was tricky because the guides blue lights were just bright enough the destroy our night vision and not see the low hanging branches. I would hope in the future that the guides would switch to red lights to make navigating in the low light easier.

WITHOUT A PADDLE…read more Kayaking during the day proving too easy?  How about kayaking at night...through a mangrove forest. As my wife and I planned our second trip to Puerto Rico, we agreed that a bio bay kayak tour should be on the list.  Only 5 biobays exist in the world, 3 of which are in PR (in Vieques, La Parguera, and here on the far northeast corner of the island).  There's a few kayaking tour companies in the area, each offering a similar bioluminescent excursion. Hang on, biolu-what?  I'll skip the TED talk--all you need to know is that a certain kind of marine plankton makes the water in extra salty lagoons glow blue.  It's the same science that gives jellyfish, fireflies, and deep-sea anglerfish their special ability to produce light. When we arrived around 8pm, tour guides gave our group of 15-20 life vests and provided instructions, like what to do if your ass falls out of the kayak.  Our goal was Laguna Grande (literally "big lagoon"), roughly 1 mile from our starting point on the shores of Fajardo. So......getting to Laguna Grande is not easy.  Along with a partner, you'll paddle your way through a narrow channel surrounded on all sides by thick mangroves, including an overhead canopy.  This is tricky during daylight hours, but at night the difficulty ramps up.  Keep in mind that visibility in these thick mangrove patches drops to near-zero at times. You might (probably will) have to avoid other kayak groups and (possibly) motorboats as you make your way to the lagoon, all while trying not to crash into the person in front of you, fall too far behind, or be knocked unconscious/impaled by low branches.  The outbound trip was not super chill, thankfully coming back was less stressful. Having an experienced partner is CRUCIAL. Bio bay tours are very much like whale watching, in that your visit is based almost entirely on luck.  A lot needs to go right in order to see magic stuff in the water, like the moon being in its 'new' phase (full moon casts too bright of a reflection) and no recent rainfall (rain comes down as fresh water, decreasing the lagoon's salinity). Under ideal circumstances, the microorganisms appear as florescent blue swirls when you move your hand/paddle through the water.  What we saw were closer to electrical 'sparks', still cool but not vibrant.  Capturing what little bio-presence we saw on camera would've been impossible, so we smartly kept our phones in the car. Oddly enough, mosquitos weren't a problem. * TL;DR * For me, this was more about the journey than the destination. If I'd hung all of my hopes on seeing tons of bioluminescent activity, I would've been disappointed.  I was focused more on trying not to capsize while also listening to the symphony of 'coqui' (the local island tree frog). It can be romantic with a spouse/partner, assuming they're not yelling at you the whole time. Wear comfy clothes (swim trunks aren't a bad idea) and be aware that parts of your outfit will be crunchy the next day, due to the lagoon water being twice as salty as the ocean. Mangroves play a critical role in the tropical ecosystem, but they stink! Would definitely recommend this to anyone over the age of 18; it's an awesome late-night adventure and one of the most unique things you can do while in Puerto Rico.

Once on site, we had a few minutes in the Margarita Bar to take a bathroom break, grab water or snack, etc. Then we went to another area to get our gear put on and then headed to the first line. Before getting started one of the guides gave instructions on what not to do with the gear, how to hold on and how to pull yourself in if you don't make it all of the way to the next platform. Next the adventure began. I don't recall the description saying that there were open-slated wooden bridges to cross or slightly steep and possibly slippery hills to climb. I can say that my nerves, glutes and hamstrings got an intense workout. lol. The last line ends back at the Margarita Bar, perfect for if you need a shot after.

I brought my kids back in July 2026 hoping to share that same experience, but the bioluminescence has faded dramatically. What was once a stunning light show is now barely a flicker. Tour operators still run the same trips at the same price without setting proper expectations -- understandable since it's their business, but disappointing for visitors. Practical tip: don't bother waiting for a later evening tour hoping for better glow. At this point it's just a regular kayak trip -- the only difference later at night is that you're paddling in the dark instead of at dusk. If you want a nice kayak outing, it's fine. If you're chasing the bioluminescent magic this place is famous for, temper your expectations.

The independent owner/tour guide's name is Erik, and no matter what I can always count on him to give the hotel guests the type of excursion they are looking for. Professionally, Erik is reliable and always communicative with important details such as pricing, pick-up time, things to bring and appropriate dress. A huge FYI to visiting tourists, many tour guides are NOT certified! If you have the opportunity of meeting Erik by booking a tour, you will see his certifications on his official badge. This is very important to how your experience will play out while on a tour. A knowledgable guide is better than one wasted money on. You can contact him through either phone, text or email and are guaranteed a response in no more than 30 minutes tops. Wow! What a breath of fresh air in comparison to other companies I have tried calling 10+ times in the past while trying to book a guest! An extra invisible 6th star for his nifty, live online booking featured on his website. By far, the easiest and most efficient way of booking on the island. If you already know which tour you are interested in booking (such as the Bio Bay. Who doesn't already have the expectation of visiting the bay?), then that is your immediate opportunity to get set up. Since I'm using the Bio Bay as a reference, I will also note that this excursion is almost (..almost!) impossible to book without a 2 week in advance reservation. However, Erik always has 14 spots pre-reserved and available EVERY NIGHT for the bio bay. People, if you are debating between companies, look no further. You have found a goldmine! Enjoy! And other concierge, meet your dream-come-true, hassle-free, easy-to-book tour company. At last!
