Great tour. Informative and fun! Tour guide Diego was the best! He helped my 12yr old daughter and I and was so patient and kind. Our experience would not have been the same without him!

I was a bit wary since we booked last minute and all of the other companies were booked up, but Island Kayaking Adventure was fantastic. After a quick safety briefing we climbed into out two man kayaks and headed out into the water. MAKE SURE THAT YOU ARE GOING ON A DARK NIGHT WITH LITTLE MOONLIGHT! It was nearly pitch black, so we followed the glowstick on the kayak in front of us. The path through the mangrove trees was good for a laugh as everyone was bumping into trees and the kayaks around them. About half an hour in, the water began to glow as we paddled. By the time we emerged into the bay, the water around us was bright. You can't get out of the kayak as your body oils are bad for the ecosystem, but you're free to paddle and splash your hands. I'm not a big kayaker, but even when my arms were tired I didn't want to stop paddling because it was so beautiful! read less

If we started late we were able to stay late. The snacks they served between snorkeling the reef and snorkeling with the turtles was homemade and very tasty. We took kayaks out to a reef at Tamarindo Bay and our guides told us about the reef and fish and pointed out interesting animals we might otherwise have missed. They also took pictures of everyone and everything, which they let us download for free. Then we kayaked back to the beach and ate a snack of sandwhiches,drinks , and chips. We then snorkeled out to the turtle side of the bay and saw many turtles eating ,breathing and just being turtles. It is thier nesting season, so you can volunteer to help these animals out if you have time. They train you on what to do. This is an awesome company. read less

It was about an hour drive. We arrived and paid our fees and were suited up and in line for the kayaks. It was all very organized. The guides were helpful if you needed them. I was happy that they let my family of three have a single kayak so we could all ride together. Going to the bay was challenging for the less experiences kayakers. We definitely had to watch out for others as they went all different directions. We all made it through the mangrove tunnel and into the bay safely. We were then lined up and able to stick our hands into the water. The glow is fascinating. We then were instructed it was time to head back. This part is challenging! You pretty much have to follow the glow sticks attached to the kayak in front of you. It was a little scary because it was pitch black and hard to see if you were about to run into the mangroves but isn't that part of the adventure? I am inexperienced with a kayak and I was worried about falling into the water. No one fell in at all and I definitely recommend giving this one a try. It is a memory you will never forget. They also supply you with a picture on their facebook page for free. read less

Hint: wear water shoes and swim suit or clothes you don't mind getting wet. Use mosquito spray.

As the group of about twenty (two person kayaks) got together in the bay, our guide gave us instructions about the path and lights again. Same instructions he gave on land. He gave a quick practice for how to stop, back up, and call what he yells back to others. He told us to watch for outgoing traffic in the narrow mangrove canal that would take us to the open biosphere bay.

We all lined up. Immediately, some had difficulty and we by-passed them. Into the canal we paddled. It grew darker as we progressed. Commands were called. Some were passed back, others we found out about when we sensed or saw the red light of the kayak in front of us stop. We never actually hit.

Finally after about 45 minutes, we were in the open bay. There we regrouped and waited for our guide's instruction.

It was kind of dark in the bay but not as dark as the canal had been. We had seen some glow worms while in the canal. Now, the guide told us we would create our darkness by using a tarp. A tarp was shared over the kayaks as we drew our hands in the waters to see the sparkles--beautiful.

When all had a turn and our second free photo was taken, we lined up again to re-enter the canal.

As we entered, we could barely see. It was pitch black now. And, there was incoming traffic--lots of traffic--including a motorized tour boat. Keeping to the right was essential. It was challenging as we were going against the tide into the large bay where we entered. It felt quite spooky--a little scary--but exciting. At least we knew the length of the canal now.

Upon exiting the canal, our kayak began to rock a bit but we maintained control. The large bay had been calm when we had entered. Now, the bay was choppy and flowing briskly.

We paddled as fast as we could in the darkness across anchor lines to the boat slip--our exit point. We felt exhausted but pleased to have experienced this unique adventure. read less

It was still daylight when we set out into the mangroves and waited for dark to arrive in the lagoon. Peaceful settings. Several guides accompany each group. Staff was very friendly and informative.
The visual bioluminescent effect is stunning. You just want to keep putting your hands in the water to see the effect over and over again.
Paddling back was a little bit more of a challenge. It is pitch black and your paddles will inadvertently pick up sea weed and drop it on you, making you believe it is something else entirely. But not to worry, it is very safe. The guides all have flash lights and will shine a light on whatever raises a concern.
The only derogatory point I can make is not against this outfit, but rather against another provider that offers the tour on a powered boat. Having to make room for these glass bottom boats was a pain. Besides, nothing beats a hand on experience. read less

Magical The bay exceeded my expectations and the float through the mangroves was magical. It was challenging paddling against the current on the return trip but the guides made us feel safe.

Well worth it! Very friendly staff that shared a lot of knowledge about the area. Was a great experience and would definitely recommend!

The bio bay is amazing. It's as if it could be something out of a movie. The sun was setting as we went into the mangrove channel, which is very narrow, and that was hard enough. It was frustrating because there are many people that have never kayaked before and therefore get in the way, hold people up, paddle in the wrong direction, cause chaos as they argue and disagree with each other, etc. It was completely dark on the way back. This was significantly harder not only because there was no light and it was hard to see, but because there were tours trying to go into the channel as we were coming out.

The bio bay was worth seeing, however, I would not do this again. read less

Great Experience They let us do kayaking next day. Great staff, patiently guided us to lagoon.
Wish they could have taken few more pics, but still thanks to them.

The staff and equipment were excellent. It is very dark and you really need to know how to kayak at least a "little". I felt sorry for the guides who had to deal with novices who slowed the whole group down. My only complaint is that the whole mangrove and bay is TOO crowded because local authorities have licensed too many tour groups. You have to stay on your toes to stat with your guide and group and not get confused by other kayaks in the channel with our tour groups doing the same thing. Kayaking at night in the mangroves and bay is cool but it is crowded. read less

There was work involved with two people per kayak and traveling through the pitch dark Mango groves. As long as the two of you work together as instructed it was not that difficult. My friend and I are 64 and 69 years old and we managed just fine. It was fun kayaking (our first time) through the darkness of the trees and challenging to follow the tiny blue light attached to the kayak in front of you. Lots of laughter and "I'm sorry" and you banged into each other and ran into the branches of the trees. When you put your hands into the water, it lights up all around your hand. In the bay, we even saw some falling stars. The guides were all extremely helpful, knowledgeable and very friendly. When we got back to base camp, we were given a light snack and bottled water. read less

Los monitores estuvieron muy pendientes de nosotros todo el rato y nos instruyeron en cada momento. El viaje hasta la laguna fue muy divertido, y una vez allí, nos contaron acerca de la fauna y flora de la zona. Nos hicieron un truco de magia, donde vimos el agua brillar (algo que realmente nunca había visto anteriormente y fue una experiencia mágica...)

La vuelta es contra corriente y a oscuras: Se requiere un poco de fuerza en los brazos, pero los monitores siguen estando muy encima tuyo, sin dejar que te pierdas.

No es para nada peligroso y ellos te van iluminando el camino.

Volvería a repetirlo sin duda! read less

Everyone has been talking about it with awe and excitement since! There were a few who had never kayaked before, and they were shown extra care and attention and were so proud they concurred fears and had the opportunity to experience overcoming fears with someone by their side. The bioluminescent bay was exciting to see and looked like glitter and sparks in the water. It was interesting to hear about the impact of hurricane Maria and the effects on the bioluminescent bay plankton.

You have to learn to communicate well with your kayak partner and was a great team building experience for us.

For those looking for details: yes you get wet from waist down. Bring a towel and change of clothes. If you go at sunset, bring bug spray - we used bug spray and no one came away with bites. Yes, it can be tiring paddling back, but you will be proud of what you can accomplish. Nestor and his crew will take good care of you! read less

They gave us custom driving directions from our hotel and the woman that checked us in was very nice and offered to lock up our wallets, etc. so we didn't have to leave them in the car. Our guides were also very nice and informative (I think our lead guide was Miguel, my apologies if I am wrong). There was a young woman in our group who had some trouble kayaking and they gave her extra attention and ended up connecting her kayak to one of the guides to help her out. Since you shouldn't bring a non-waterproof camera, they even take your picture and then post it on their Facebook page so you can download it for free. Once you get to the lagoon, they pull out a big tarp to put over all the kayaks to make it extra dark so you can see the glow better (it's really more like sparkles in the water). Overall, it was a great experience and I'd recommend them. Just don't believe the pictures on their website and brochures. I highly doubt the glow is ever that intense. read less

There are 5 or 6 operators that do these tours and they all seem to have same equipment, same prices and same schedule. Island Kayaking Adventure is one of them, I guess as good as any. Everything was well organized, on time, guides were informative, friendly and very helpful. My wife and second kid were having troubles paddling their kayak so one of the guides hooked them up to his boat and pretty much dragged them in and out all the way, which was great help. I strongly recommend the first tour so at least you have some light on your way in and don't have to bump into other boats that go in opposite direction. Return can be spooky for small kids because by then you would be paddling in almost complete darkness and bumping into trees branches and other boats. But considering how amazing this glowing water is - it's totally worth the money and effort. read less

There are multiple companies doing the same thing at the same time so it can be overwhelming at times. Our group had 4 guides with 15 kayaks. We went at 6pm, but the best time to go is the 8pm option because the darker the better.
Warning: this isn't a relaxing experience! You have to actively paddle your kayak (it's a double seater) for a solid 45 minutes (one way) in an extremely narrow canal in darkness. Each company's kayak has a colored light at the tail end so you can identify where your groups is. And with so many companies going at the same time, it gets chaotic, especially since you can't see anything. I was disappointed to see that there is a company with boats that go up and down the canal with the kayaks- very dangerous! Once we reached the lagoon, we all floated together holding on to each other's kayaks until it was dark enough to see the lights in the water.
The lights cannot be caught on camera, perhaps video. One of our group members lost his go pro so try not to bring anything! In order for the lights to show, you have to wiggle your hands/foot/paddle in the water. The way back would have been cool if we weren't stuck behind a boat with it's back light on, meaning the lights in the water couldn't be seen. This is something you had to do in Puerto Rico because I'm pretty sure its unique to this island, but I wasn't too impressed.
At the end of the tour, they have snacks and water. They take two pictures, which they post online for free.
You will get very wet so bring a change of clothes. The women's restroom only has 2 stalls (never any toilet paper) so be prepared for a long line. read less

I choose the right evening as the moon was small, so seeing the light of those flagellates was amazing. I also lucked out in being by myself that i had the pleasure of being in the first kayak, first seat on the venture to the bay. Thank you Miguel for making me feel so comfortable...i had kayaked before so I'm thinking i did most of the paddling while he was busy coralling the group. The guides remained professional and kind, especially to the inexperienced paddlers. Their patience to try to ensure all have a memorable time is to be congratulated! Thank you again!

Pretty Cool This experience was good. Didn’t see much light in the water. But kayaking down the canal was pretty cool. I highly recommend long sleeve and pants….. and BUG SPRAY!! My whole group got a lot of bug bits!

Amamos Passeio imperdivel para quem visita Puerto Rico. Muito lindo e mágico.
O passeio é muito bem organizado e o guia explica tudo sobre esse espetaculo da natureza.

Amazing experience The guides were clear and always on top of everything. The Fajardo Bioluminescent Bay tour lasted a long time but I only wished we had stayed in the bay more since we had very little time to play around in it.

Awesome! Awesome adventure. It was fun.
Easy paddle and just enough distance/time to enjoy biobay.
The guides were very knowledgeable in answering our questions.
Do not pass this unique experience.

It is pretty well organised but it could be said that the group was too large with some inexperienced kayakers causing confusion. The guides are good and friendly and thye bay is well worth visiting. However, most of your trip is spent paddling to and from the bay along a narrow canal with over-hanging mangrove trees. Not for the faint hearted! If you trust yourself in the water, take a camera (or take a water-proof one); the guide takes a photo of you but it is not great quality. read less
