Explore the Natural Bioluminescence in La Parguera! On your tour of the Bioluminescent Bay in La Parguera, you will be amazed by a truly unique natural spectacle: **Bioluminescent Display:** As you enter the bay, the water will glow with a magical light. This phenomenon is caused by dinoflagellates, microscopic organisms that emit light when disturbed, creating a brilliant and magical blue-green glow. **Luminescent Effects:** You will see how every movement in the water triggers a radiant effect that spreads and shines around you, creating a fascinating light show that appears to float on the surface. The glow from the dinoflagellates reflects and amplifies, offering an impressive visual experience that you won't find anywhere else. This tour provides an unparalleled opportunity to witness and experience one of the world’s most extraordinary natural phenomena in its purest and most magical form.

Such a fun experience! The water bikes were surprisingly easy to ride (not too strenuous), having that experience alone was really amazing! Mariemma and her team were extremely knowledgeable, prioritized safety, find the best spot for bioluminescence, and implement actions to preserve the bioluminescent bay. It was the best part of our trip! Thank you Mariemma and team!

Had a great time! Our guides were very knowledgeable and let us experience this to the fullest. We went out before the full moon and we still got to see the glowing effect. The stars were beautiful as well.

The meeting point is at the end of a street by the water. Wear shorts or pants you don’t care to get wet. Make sure to stretch and take pain medication if you have pain in your legs you will be pedaling a lot.

This is an amazing experience. At first it will appear difficult, but the tour guides (Mary and Waldie) were very helpful and provide a lot guidance to calm your nerves. Once you get into the pedal boat and began pedaling across the water, it is like riding a bicycle across the ocean. It is peaceful! You will get a good workout pedaling across the ocean to the lagoon, but it is better than taking a boat - great exercise. My wife was so excited and loved kicking her feet in the water, watching fish light up the water when they passed by us. The water was warm and peaceful. There were fish jumping around us in the water and swimming by, one fish brushed against my wife’s feet. Mary shared a lot of scientific information about the species that creates the light in the water, it was beautiful! I would do it again.

A really cool experience. The boats were very stable and my husband who gets motion sick very easily was totally ok. Pedaling doesn’t require much force and the guides are very respectful of nature.

The bioluminescence was an experience. The travel by chiliboat was even a good time. The tranquil nature at night makes you enjoy it even more.

Had an amazing time with La Parguera by Caribbean Chillboats! It was our first time trying the biking kayak and it was a lot of fun. We saw plenty of the blue bioluminescent light, which was incredible. I also appreciated how much they cared about preserving the space so future generations can enjoy it too. Highly recommend! — Jorge
