Bioluminescence in La Parguera, Puerto Rico.

During your visit to Puerto Rico, this is a must-do experience—enjoy this natural phenomenon on a unique Chiliboats Waterbike adventure.

Tiny microorganisms make the water glow at night, creating sparkling light with every movement of your hands or feet.

We will pedal for approximately 25 minutes on our Chiliboats Waterbikes to reach the bioluminescent bay. Unlike traditional kayak tours, this experience offers greater stability, comfort, and smooth pedaling.

This bay is part of a protected natural reserve, where you can enjoy the ecosystem and, on clear nights, a sky full of stars.

All tours are conducted on double Chiliboats. Participants must meet height (54" – 6'5") and weight limits (240 lbs per person / 450 lbs combined).

Join our professional local guides and enjoy one of the most unforgettable nighttime experiences in Puerto Rico.

    There was minimal bioluminescence because of a bright moon, but a very cool experience to pedal out to the mangroves at night. Guides were knowledgeable, friendly, and competent. We are 58 and 64 years old, in decent shape, and we found Chiliboats were easy to pedal.

    This was an amazing experience. We were lucky to be able to book it during a new moon, so no moonlight to interfere with the bioluminescence. There were also almost no clouds, so we were able to see all of the stars since were out away from any city lights. The staff were all friendly and helpful. They'll guide you through how to manage the boats, etc...and the guides are very knowledgeable about the lagoon and the dinoflagellates. Paddling out to the bioluminescent part of bay took maybe 20-ish minutes, and we spent about 20-30 minutes there. It's pretty easy padding, especially with 2 people per "boat." You'll notice the glow in the water around the propeller before you officially arrive. It looks like someone cracked open a glowstick and dumped it in the water, a bit milky and subtle, and it lasts only as long as you agitate the water. You'll also see a few sparkles. In all the pictures I've seen the glow is blue, but for us it was actually white. The guide will tell you the color can vary depending on the environmental conditions. If you want to get away from noise and spend quiet time in the water surrounded by stars and a magical glow in the water, this is it. It was relaxing, tranquil, and fun.

    This activity was a lot more difficult than I was expecting. It would be great for teens/young adults with lots of energy, buy for me, it was a struggle. You have to pedal a long was to get to the bio bay (and back) Unfortunately the conditions on the night we went were not great so we did not see much. (Of course, not Chillboats fault) The guides were great and I learned a lot about bioluminescence.

    Wonderful experience. I was a little iffy about pedaling a floating bicycle boat in the ocean at night, but they made the experience feel very safe. We were able to see the Micro-organisms light up and we went to many different spots in the bay to see them multiple times. Excellent experience. Highly Recommend. I recommend wearing Swim clothes and water shoes, with a change of shoes once you get back. You can lock your stuff in your car as someone is there to watch the cars.

    We drove three hours across the island to do this excursion only to find that my son was over the weight limit. There was no limit in the listing when I booked. We spent a whole half day of our four day trip to come over and do the excursion. Very disappointed.
