Phosphorescent Bay (Bahía Mosquito), Vieques

Good forOutdoor lovers

The water moves and the water glows. Bahía Mosquito, off the southern coast of Vieques, holds one of the highest concentrations of bioluminescent dinoflagellates on earth — microscopic organisms that produce chemical light when disturbed. The bay is best experienced on a moonless night, when the darkness makes the biology impossible to argue with.
