About these ratings

This south Vieques beach might not sound like much, but it's one of travelers' favorite experiences in Puerto Rico.

During the day, Mosquito Bay is your stereotypical Caribbean hideout-- but at night, the sky and waters emit a bluish glow from the half-plant, half-animal microorganisms that live there. According to the bay's website, there are more than 700,000 bioluminescent dinoflagellates in each gallon of bay water, and recent travelers that have swum amongst them are amazed by just how much visibility these tiny creatures provide. Avoid visiting the bay during a full moon; the microorganisms aren't as visible then.

Though you can visit Mosquito Bay unaccompanied, most suggest you spring for a tour of the area. Mosquito Bay's official site offers tips on the best nights to visit and lunar calendar information, as well as details on eco-friendly tours.
