The Bioluminescent Bay (also known as Puerto Mosquito, Mosquito Bay, or "The Bio Bay"), is considered the best example of a bioluminescent bay in the United States and is listed as a national natural landmark, one of five in Puerto Rico. The luminescence in the bay is caused by a micro-organism, the dinoflagellate Pyrodinium bahamense, which glows whenever the water is disturbed, leaving a trail of neon blue.
Kayaking is permitted in the bay and we are one of a few local vendors authorized to do so with small groups. We can take you there. Book one of our tours now!
