Meet your Captain on this unique tour. He has the knowledge, experience, and passion for his work. He will explain how the bioluminescent bays glow, and you will see your friends and yourself glitter in a spectacular way. He will also talk about the history of La Parguera. La Parguera is very interesting and special; it’s one of three bioluminescent bays found along Puerto Rico’s coastline. The bay’s glowing effect is made possible by micro-organisms called dinoflagellates, which emit a short burst of light when the water is agitated. La Parguera is the only Puerto Rico bio bay tour that actually allows you to go swimming in a bioluminescent bay. For this reason, it’s very unique.
