Experience the Magic of Puerto Rico’s Bioluminescent Bays

Puerto Rico is fortunate enough to be home to three of the five bioluminescent bays found in the world; Laguna Grande in Fajardo, La Parguera in Lajas, and Mosquito Bay in Vieques.

Puerto Rico’s bio bays are easily some of the most popular and awe-inspiring destinations on the island. Don’t miss an opportunity to kayak at night and watch the water illuminate in shades of blue, green, and white.

Want to know what makes the water in Puerto Rico’s bio bays sparkle and glow? The bays are populated by millions of microorganisms called dinoflagellates who make their food by photosynthesis, which is the source of this spectacular glow. A little agitation of the water - whether it be by a kayak’s paddle or you hand, and the water lights up with this amazing microorganisms.

If you’re wondering when the best time to see the Bio Bays we’ll help you time your visit accordingly

Regardless of which of the three bays you choose, you won’t forget this amazing experience.

We had an amazing time. I’m so glad that a group cancelled so we got to experience the Bio Bay tour. Guides are very helpful, friendly, and definitely amazing. I still have pending places that I didn’t visit, but planning on going back soon so I can visit them with this tour company.”

“The highlight of our vacation! What a unique experience. It really does glow. You do want some level of fitness to keep up and wouldn't recommend if you are nervous on the water in the dark. We went a few days before a full moon so it was bright out, but we still got to see the glow!”
