Review:
Mosquito Bay, also known as the BahÃa Bioluminiscente, is widely considered to be the most beautiful example of a bioluminescent bay within the United States, designated as one of five National Natural Landmarks within Puerto Rico.
The bay's unique neon blue luminescence is created by populations of the dinoflagellate microorganism Pyrodinium bahamense, which glows brilliantly whenever the bay's waters are disturbed. The small channel that is now most associated with the bay was originally created by Spanish ships attempting to choke the bay during colonial times, as the Spaniards believed that the bioluminescence was the work of the devil. Kayaking is permitted within the bay, with rentals and tours offered from a number of local companies.
