Bioluminescent Bay, Fajardo

3.5
Marvel at an unusual natural phenomenon at Bioluminescent Bay, one of the only locations in the world home to the glowing organisms. The creatures themselves, a type of plankton, emit a glow when disturbed or touched. Join an excursion offered by one of the many tour companies in the area, and you'll make your way through the darkness to the lagoon, passing through mangrove swamps along the way. Keep in mind that conditions may not always be ideal for viewing the glowing critters, and you'll need a reservation with a tour group in order to visit.
