6Mosquito Bay, Vieques, Puerto Rico

Mosquito Bay in Vieques, Puerto Rico, is often hailed as one of the brightest bioluminescent bays in the world. The bay is home to millions of microscopic dinoflagellates, which emit a stunning blue-green light when agitated.

It is a truly magical experience to kayak through the bay at night, where every stroke of the paddle and every fish darting beneath the surface leaves a trail of sparkling light. The result is a surreal journey through a starry aquatic realm, earning Mosquito Bay its nickname, “Bio Bay.”
