There are only a handful of destinations where you can experience the Bioluminescence phenomenon and Cayman is fortunate enough to be one of them!
Bioluminescence is the emission of light from the extremely high concentrations of bioluminescent phytoplankton that live in the water. When disturbed, they emit a burst of light flash lasting a fraction of a second. This light emission is used as protection to scare predators.
The Bioluminescent Bay is located on the North Side of Grand Cayman. It is a 10-15 minute kayak from Rum Point, Starfish Point and Kaibo, and approximately a 45 minute ride by boat from Seven Mile Beach.
In order to experience the full Bioluminescence phenomenon, this tour requires a dark sky in order for the bioluminescence to be seen properly. Therefore most tours only operate this tour at certain times of the moon cycle. Usually the week before and the week after the New Moon.
Bear in mind that many other factors will affect the visibility of the glow level and brightness. These factors include temperature, weather and tides.
During the summer months, the Bioluminescent Bay is generally packed with small jellyfish that may sting you if they are disturbed.
