Bioluminescence in Mosquito Bay
United States
The brightest bioluminescent bay ever recorded, glowing blue-green with every movement in the water.

On the Raa Atoll island of Vaadhoo, plankton blooms can make the waves glow electric blue as they break on the beach. Photographs of this sea of stars made the island famous, and similar glowing shores appear on nearby islands.
In season: Jun–Dec · Peak: Aug–Nov
A natural phenomenon that is never guaranteed, best on dark nights, with warm water and quiet island stays. Resorts nearby arrange night walks.
Stay in Raa Atoll and ask locally about recent blooms. Walk the beach after dark on moonless nights, keeping lights off.
