5-hour kayaking tour of a bioluminescent bay in Puerto Rico
Fully narrated small-group tour
Kid-friendly tour ideal for the adventurous family
Paddle through “Big Lagoon” on a guided evening tour
See the water light up with the natural glow of light-producing organisms
Meet your guide at your hotel in the San Juan, Rio Grande, or Fajardo areas prior to a 3:30 p.m. tour departure time. With your small group and your guide, head to the “Big Lagoon” to begin your kayaking tour of a bioluminescent bay, one of the most popular attractions in Puerto Rico.
Paddle through a mangrove forest and watch the lagoon light up with the natural glow of bioluminescent organisms that produce a blue-green light. Although it is generally too dark for photos, the patterns of light and movement on the water are memorable in their own right. Learn about the organisms as you go from your guide, who will provide narration throughout the tour.
Return to your hotel at the end of the trip.
Please note: This tour is recommended for travelers who feel comfortable paddling about one mile. Visitors who come between November and January may not see as much bioluminescence due to cooler temperatures.
A neat experience. The guides were great. The only issue was the long, long ride there from Old San Juan....about two hours in a super bumpy van. Then we had to wait an hour before the start of the tour. The kayaking was awesome, though. It was a beautiful, peaceful night and we enjoyed all we learned.
This tour was way beyond our expectations. All the staff was really friendly (from our driver Jerry to our tour guy Ivan) and they are really passionate about their jobs. They tried to set expectations to avoid people think that what we were about to experience will be like the pictures, but because of that, it was even more amazing that I can describe. There was new moon, so we can see the light really good and clearly. We were really happy that our 7yo was able to see this marvel. Totally recommended to the point that we will gladly come back.
This is a MUST!!!! Amazing. Wonderful. Had a wonderful time. The staff is very friendly and helpful. I kayak myself so this was an easy trip but several people had no clue on how to kayak even with instructions. Staff was patient but not the safest set up or I would of given 5 stars. THIS TRIP is worth it. JUST GO :)
Unfortunately we visited the PR during the week of full moon, we knew what to expect. First a five star to our driver Jerry, very well communicated ahead of time and picked us up as scheduled. Very knowledgeable, turned the hour bus ride a fun way. Kayaking is awesome, my 6 yrs old and 14 yrs old loved it! Giving the wind and bright moon, our guidance Jay used a tarps cover us so we can see the shines creatures, great experience, definitely worth it.
While the actual bio bay was amazing and beautiful, the tour company was a complete mess. Pickup from the hotel was normal until the driver didn’t have enough seats for all of us in the van, which left me sitting squished with other random travelers in our group for an hour from San Juan.
When we arrived, the instructions were so unclear. Do I put my bathing suit on now? Where am I leaving my bags? What shoes do I wear? They told us to bring all this stuff so I was left completely confused when we got there. Tip: wear your bathing suit with a shirt and flip flops.
We waited about 2 hours watching the tour company slowly bring out life jackets and boats for us. They kept running out of stuff because there were tons of other groups that showed up. It was just an organizational mess.
Finally when we got in a kayak, there were no instructions. So we just played follow the leader but our guide was too fast and we lost him. We were kayaking out in the ocean in the complete dark unknown where we were going for a mile. Luckily we could hear some voices and just hoped we were going the right way. Kayaking in the ocean was completely exhausting and felt like they were trying to make us go faster. We are a fit couple in our 20’s so this shouldn’t have been so difficult. Our tour also had some older ladies who weren’t able to keep up.
When we came ashore, we had to drag our heavy boats across the road into the lagoon where the glowing plankton were. Kayaking in the actual lagoon was AMAZING but it was short and before we knew it, we had to drag our boats again and paddle allllll the way back.
This is where I got really upset... the water droplets off the paddle and waves caused my clothing to be extremely wet (this is normal). They asked us in the tour directions to bring a change of clothes (which I had) but there was no where to change! The restaurant kicked out all tour groups from using the restroom and the guide just sorta shrugged his shoulders. Why wasn’t there a place to change?! After all of us complaining, we stopped in a parking lot where I changed around a towel. Sketchy af.
Recommendation: Take a different tour.
The kayaking was lots of fun and the guides great - that we really enjoyed. As we had quite a moon we didn't see much of the bioluminesence, but that was risk, So if you really want to see just that be sure to pick a day of little or no moon.
What could improve is the trasnport, we were picked up at 3:30 in San Juan, then stayed at a beach for 1h30 we didnt know about the stay so werent prepared. Then sat in the car for 45 minutes as part of the group was late and we just had to wait. We suggest that there should de a late tolerance policy - advised to the passengers and if not respected leave them behind.The actual tour is at 7 PM so very early pick up for a later tour.
But in all very responsible group with great guides in the water.
The Bio Bay was very cool, and I would definitely recommend going. We were picked up from our Airbnb which was really helpful. The drive from San Juan to Fajardo was about an hour. Once you get to Fajardo, you get time to get dinner before kayaking. Make sure to bring extra clothes because you will get wet from kayaking. You can change in the bathrooms in the park next to the marina. You can leave belongings in the van while you are kayaking. It was slightly annoying to try to kayak in the dark with people who had never kayaked before, but if you can get to the front of the group you don't have to worry about people running into you. Our tour guide Jonathan was awesome!!
Very friendly staff and very knowledgeable about the area. We were picked up right on time and given lots of time to get out of our wet bathing suits. It was a lot of fun to paddle through the very dark mangrove area and into the lagoon. The only disappointment was that the bio luminous was not as bright and obvious as what was shown in the advertising. This MAY have been a condition of the waters that night, but I think the pictures posted on the webpage for this tour were greatly enhanced. However still a fun time. Cannot add pictures because it was too dark for photos.
