Puerto Rico is home to three bioluminescent bays.
One of these bio bays is the brightest in the world.
I’ve been living in Puerto Rico for 14 years and have been fortunate to have experienced this magical phenomenon.
In this article, I will cover the 11 best bioluminescence tours in Puerto Rico:
Eco Actions Tours is located in Fajardo and takes you on a magical tour of the mangrove channels of Laguna Grande.
The 2-hour tour duration is perfect for beginners and for the family.
However, it is important to note that this bay is significantly less bright than Mosquito Bay on Vieques, the brightest bio bay in the world.
This includes kayaking safety and orientation upon going on this tour.
