What Is a Bioluminescent Bay?
Bioluminescence is the natural light produced by microscopic organisms called dinoflagellates. When disturbed—like by paddling through water or running your hands across the surface—they emit a neon-blue glow. It’s like nature’s very own magic show, and Fajardo Bio Bay Puerto Rico is one of the few places in the world to witness it.
Puerto Rico is home to three bioluminescent bays: Mosquito Bay in Vieques, La Parguera in Lajas, and Laguna Grande in Fajardo. The one in Fajardo Bio Bay Puerto Rico is the most accessible, especially for those staying in San Juan or the east coast.
Where Is the Fajardo Bio Bay Puerto Rico?
Fajardo Bio Bay Puerto Rico is located in Laguna Grande, inside the protected Las Cabezas de San Juan Nature Reserve. The area is lush with mangroves, winding canals, and a sense of untouched Caribbean serenity.
From San Juan, it's roughly a one-hour drive, making it a perfect day or evening trip. If you're staying nearby in Luquillo, Rio Grande, or Fajardo, it’s even closer.

What Should You Bring to Fajardo Bio Bay Puerto Rico?
-
Water shoes or sandals (you will get wet)
-
Dry bag for valuables
-
Change of clothes for after the tour
-
Bug spray (reef-safe if possible)
-
No flash photography (it ruins your night vision and affects the experience)
Pro Tip: Don’t wear white clothing—it glows from the dinoflagellates and may stain during your Fajardo Bio Bay Puerto Rico adventure.
Why Choose Fajardo Bio Bay Puerto Rico Over the Others?
While Vieques’ Mosquito Bay is the brightest, it requires a ferry or flight, and Lajas’ bay allows motorboats, which reduce the magic. Fajardo Bio Bay Puerto Rico is easily accessible, eco-friendly, and family-friendly.
