Want a glowing and unforgettable night? This Bio-Bay Kayak Tour is what you need!
On this tour, you will cross a canal inside the nature reserve that is surrounded by various types of mangroves. This protects from strong winds and helps you to paddle easily in peaceful waters.
The best part of this tour is to enjoy the incredible glittering water of the "Big Lagoon"! Tiny bioluminescent organisms called "pyrodiniums bahamenses" are the responsible for this wonder of nature. They produce blue-green light from top to bottom of this bay every time you touch or move the water with your kayak!

5.00Had a great time, was glad we took the earlier trip, it was easier to navigate through the mangroves and we still saw the bioluminescence. Had our 6 year old with us and she had a great time. The guides were great!
Just do it

5.00One of a kind experience. Great guides. You will get wet and your clothes will be stinky after, but it is 10000% worth it.
Don’t waste your money!

1.00What an absolute joke. From the rudeness of Maria who couldn’t answer questions about the trip and just pushed to get your money. To the absolute joke of a trip that is Misrepresented completely. Here’s a more accurate description for you to make your own decision: Experience the Magic of Bioluminescence! Join us for an unforgettable evening including more than an hour of aggressive bumper-kayaking through ‘Eau de Porta Potty Lagoon’ Navigate a floating traffic jam of confused tourists, vacation-fighting couples & families, and conservative college kids out past curfew powered by pure adrenaline & a speck of rebellion Absorb mystery splash back aromas directly into your pores Then, at last… witness nature’s wonder!* *By witness, we mean aggressively slapping a 6-inch strip of water while trapped under a construction tarp. Scent of essence of middle school gym mixed with eau de latrine is included at no extra cost.* For one magical moment, someone near you may even see a tiny blue sparkle before morale completely collapses. Bioluminescent Kayak Tour Come for a (potential) view of the Northern Lights of the Ocean. Leave smellin’ like a backed-up porta potty at a southern catfish fry 😜🤣😂

5.00Paddling can be difficult and crowded but it’s quite an adventure. It is operated smoothly & efficiently, with enough charismatic guides for the large group & free water/snacks at the end. Not to mention how cool bioluminescence is.
MMM... not to great

3.00I selected this option... because I thought that since they use KAYAKS to experience the BIOLUMINESCENCE,, I would be able to see it more clearly. Because there are other places in Puerto Rico,,, like in la Parguera.. but there they now are using I believe, electric motors on the boats, because long time ago they were using gas-powered boats,,, and it was affecting the microorganisms. I was disappointed,, the bioluminescence was very dim.. they even used a dark tarp over the people on the KAKAKS in order to be able to see it.
Terrible Company

1.00If I could give negative stars I would. We arrived at 6:45 as our ticket stated and were told that the group organizer messaged us to be there at 6:15. We traveled all the way from NH and we were dying to see this and they wouldn’t let us go on account of showing up at 6:45. They refused to give us a refund as well.
It was a good experience....

4.00It was a good experience. Although it wasn’t bright that night they called ahead and gave us the option to cancel which was very professional. Kayaking back was hard because you’re obviously tired so bring your muscles! I recommend the earlier slot so you can see your way out.
