Puerto Rico is home to three of the world’s five bioluminescent bays, where the water literally glows at night thanks to microscopic organisms called dinoflagellates.
It’s like watching the stars shimmer beneath the surface: a rare, almost otherworldly phenomenon that travelers can experience firsthand.
But beyond the magic, these bio bays are also a story of conservation. Thanks to dedicated efforts to protect these fragile ecosystems, Puerto Rico has been able to preserve and sustain these natural wonders for generations to come, giving travelers an experience that goes far beyond the typical beach vacation.
Here’s a quick look at what makes each of Puerto Rico’s bio bays special:
- Mosquito Bay (Vieques) – The brightest bioluminescent bay in the world, according to Guinness World Records. Its glow is incredibly intense due to the high concentration of dinoflagellates, best experienced on a moonless night. No motorized boats are allowed, keeping it pristine.
- Laguna Grande (Fajardo) – The most accessible bio bay, just an hour from San Juan. Kayakers paddle through a mangrove-lined canal before reaching the glowing lagoon, creating an unforgettable tunnel-like journey to the light.
- La Parguera (Lajas) – The only bio bay in Puerto Rico where swimming is allowed! Visitors can take boat tours and jump in to see their movements glow in the water, offering a more interactive experience.
Now is the time to discover how Puerto Rico is leading the way in sustainable tourism while offering visitors an experience they won’t find anywhere else.
